From July 15 to August 5, we participated in ‘‘2018 Asia-Pacific-Euro Summer School on Smart Structures Technology (APESS-2018)’’, which was held at Qingdao University of Technology (July 15 - 27) and Harbin Institute of Technology (July 28 - August 5). During July 23 to 25, we also attended the 7th World Conference on Structural Control and Monitoring (7WCSCM), where 17 keynote sessions and more than 500 conference presentations were delivered, including two of them from our lab given by Dr. GOI Yoshinao and M2 student MA Xinda.
The theme of the summer school consists of ‘Knowledge’, ‘Practice’, ‘Culture’, and ‘Friendship’. We were given lectures about the state-of-art techniques of smart structure, took technical visits to long-span bridges and high-speed railway vehicle workshop, joined sightseeing to places of interests in the two cities (we even watched Peking Opera rehearsal in Harbin), conducted experiments of on-site vibration test and system identification, active control, and also acoustic wave emission; furthermore, we managed to complete a group project of crack detection based on computer vision technique. Altogether, more than 35 lectures were given by experts in structural dynamics, active and passive control, machine learning, and other cutting-edge structural health monitoring techniques, from which we learned a lot about the latest research; also thanks to the arrangement of technical visits (e.g. subway construction site) and sightseeing in Qingdao and Harbin, which enable us to experience the culture and development of civil engineering in China in an immersive way.
During the last three weeks, we spent quite a lot of time with members in the summer school (especially those in our group), who were from different countries around the world: America, China, Ecuador, Egypt, Germany, Italy, Japan, Korea, Mexico, Mongolia, Vietnam and Saudi Arabia, etc. They were all so kind and we indeed had a great time together. This is one of the most precious experiences in the summer school.
Thanks to the lab, we really appreciate that we were given the opportunity to join such a meaningful activity, in which we broadened our horizon of the development in our area, communicated with our peer from both academic institutes and the industry around the world, and last but not least, such experience simply made us more motivated in research and our lives.

Report of Attendance and Presentation in IABMAS2018. Melbourne, Australia
Author: Takuya MIMASU (M2)
Date: July 9th~13th, 2018
Venue: “Melbourne Convention and Exhibition Centre”. Melbourne, Australia
IABMAS2018 is the 9th International Conference on Bridge Maintenance, Safety and Management. In this conference, researchers and engineers in the field of bridge maintenance and management discuss their various topics and enhance each other. I presented a research entitled “System identification of a bridge by a sparse-like system matrix”. In this session, a great discussion in a part of Q&A was done by experts having high knowledge and motivation, so that it was a great learning opportunity. However, I could not answer exactly as I thought in the session. I again realized enough my inadequate English skill, but fortunately during lunch time after the session, some experts and Ph.D. candidates came to me to discuss my research topic, so I could discuss with them and obtain some feedbacks and suggestions regarding my study.
To attend this international conference was a very good experience for me. I was excited and motivated by great presentations and great discussions. I would like to appreciate prof. Kim and our laboratory giving a good opportunity and support to me. Also, I would like to make my effort to do my research very hard!!

D1 Student Lu Xuzhao attended the 2017 Asia-Pacific-Euro Summer School on Smart Structures Technology (APESS)
Author: Xuzhao Lu (D1)
Date: July 17-Aug 4, 2017
Venue: Yokohama National University, Japan
This summer I attended the APESS program held in Yokohama National University. The summer school invited excellent experts in civil engineering, structural dynamics and control, smart structures technology, and structural health monitoring from all over the world to give lectures about their research progress. Besides, I also took part in the ANCRiSST held at University of Tokyo. This workshop aims to develop synergies among researchers in various disciplines that will facilitate joint research projects. The workshop provided activities including five keynote lectures by prominent leaders in the field, a discussion session to deliberate on future activities, and parallel sessions for more than 75 papers on various topics.
As for my own research field, Prof. Fujino and Prof. Su’s research expended my knowledge in vehicle-bridge interaction system. Another research that left me strong impression was Prof. Soga’s advanced sensor. His team used optical fiber to examine the change of spectrums to detect the structure condition. Besides, this sensor can automatically exclude temperature influence. What’s more, image recognition technology and robots have been tested widely in other scholars’ research. It seems that the traditional bridge engineering tends to become an interdisciplinary which combines artificial intelligence, big data processing and powerful inspection technology.
I feel so lucky to get this opportunity to get in touch with such a grand catalog at this stage. Lectures and meetings help me understand some basic knowledge in other research fields and inspire new ideas for my own research. I also learn a lot from my eminent teammates from other countries in the final group project. Collision of acute minds developed perfect work. Our cooperation won the second prize in the competition. This is absolutely an unforgiven experience in my research career.

Activity Report of field experiment on a long span arch bridge in Myanmar
Yadanarpon Bridge
Author：Takuya MIMASU(M1)
Date：Jun. 19th ～ 22nd, 2017
Place：Mandalay in Myanmar
Member：Prof. Kim, Mimasu (M1), *Hayashi (D2), *Oshiro (M1) *Structural Mechanics Lab.
The vibration test was conducted on a long steel arch bridge in Myanmar so as to develop structural health monitoring techniques. In this field experiment, 3 teams consisting of vibration team, bolt team and floor beam team conducted each target experiment, and we were in charge of the vibration team. The main objective of this experiment is to measure the ambient vibrations from accelerometers installed on the bridge. The cables for sensors were installed on Jun. 19th to 20th. After that, the measurement of accelerations was conducted until in the evening on Jun. 21st. The sensors and cables were collected and the experiment was finished on Jun. 22nd. Since we obtain some sets of vibration data, we will enjoy analyzing these data.
Through this field experiment, I recognized the necessity of wireless sensors again because wiring took too much time and effort. The field experiment in a developing country was very rewarding and gave me a great stimulus. In addition, we collaborated with teachers and students from Mandalay Technological University and this experience became not only exciting but also valuable for me. I would like to make use of this experience in my research activity from now on.
I would like to appreciate Prof. Kim and our laboratory for this precious opportunity.

Author: Oscar Sergio Luna Vera (D2)
Date: June 5th – 8th, 2017
Venue: “Universidad Politécnica de Madrid”, Madrid, Spain
This June I made a presentation about my research entitled “Energy Capacity Influence on Modal Parameters of Prestressed Concrete Box Girders” in SMART 2017. This was a joint conference that hosted two simultaneous parallel Conferences, the 8th Thematic Conference on Smart Structures and the 6th International Conference on Smart Materials and Nanotechnology in Engineering. Many researchers and engineers gathered from all around the world. For that reason, I had the chance to hear interesting researches not only from my field, civil and structural engineering, but also from different background such as mechanical and aeronautical engineering. This helped me to have a broader sense in my research purpose. After the conference, I had the chance to experience Spanish food for the very first time and became captivated with “Tapas” and “Cañas”. Moving around the university and the city of Madrid was easy since my native tongue is also Spanish. At the end of the trip, I felt grateful with my laboratory and university for the amazing opportunities and support they give me.

16th World Conference on Earthquake Engineering (16th WCEE): Report of attendance
Author: Laurensia Marcelina Anggraini (M1)
Date: January 9-13, 2017
Venue: CasaPiedra Convention Center, Santiago, Chile
I got the chance to participate in the 16th World Conference on Earthquake Engineering, one of the largest conference in the field of earthquake engineering. More than 4000 papers were submitted to this conference, more than half were presented in posters while the rest were done orally. I orally presented my paper with the title: Seismic Response Analysis of Urban Highway Viaducts under Multiple Vehicles Subjected to Strong Earthquakes. It was under 99SS session related to Non-linear Dynamics and Wave propagation. The conference lasted for 5 days, but I only attended it for 1 day due to time limitation. On each day, the conference started with a keynote lecture. Unfortunately I could not really focus on the lecture due to jet lag (there is 12-hour difference between Chile and Japan). My presentation was at 7 p.m. and by that time I did not feel any jetlag, I felt lucky that my session was done at evening. On the discussion time after my presentation, I got some feedbacks and suggestions regarding my study. One interesting suggestion by Prof. Colin Taylor of University of Bristol was regarding old light-weight bridges in European countries, on which the mass ratio of the vehicle to the bridge are relatively large. After the conference, we met Professor Kim’s friend, Prof. Fernando of University of Concepcion who also attended the conference. We had dinner at a Chilean food restaurant. The food was delicious, but we could not finish our food because the portion was too big for us.
Attending this conference is a good experience for me, 16th WCEE was the largest conference that I ever attended, I got feedbacks and suggestions from other researchers, also I got the chance to eat Chilean food and do some sightseeing in Santiago.

香港の香港科学技術大学で学会発表を行った．修士2回生を中心として，張先生を含めた5人での出張である．会場となる香港科学技術大学は海に面しており，時より流れてくる海風は心地よく，また周辺に広がる森林と相まって，長閑な雰囲気を味わうことができた．他の学生の発表は時間と会場が別だったため，聞くことができなかったが，概ねうまくいったと聞いている．個人的にも発表，特に質疑に関しては込み入ったものではなく，基本的なものだったのでうまく対処できた．同セクションでは，他に韓国，シンガポール，台湾，中国の学生が出席しておりそれぞれ特徴があって非常に興味深かった．印象としては「日本，中国，韓国」「シンガポール，台湾」に分けられ，後者はより発表に対する慣れを感じた．
食事は飲茶(点心)を堪能した．特に蒸料理は食材の旨みが凝縮されており，とても美味しかった．街では，人が多く夜になると，其処等じゅうでダンス，歌などの宴が行われておりエネルギッシュな雰囲気がとてもよかった．
以上が香港学会での報告になります．総括すると「静」の日本，「動」の香港といった感じでした．残念ながら金研の学生は最優秀発表賞を取る事はできませんでしたが，また来年に期待したいと思います．ありがとうございました．

Report of summer stay in Queens University Belfast
Author: Souichirou HASEGAWA(M2)
Date: Aug. 8-31, 2016
Place: Belfast, UK
【背景】
近年，橋梁や道路の健全度評価において走行車両から得られる情報を利用する間接的手法の研究が進められている．直接道路や橋梁に多くのセンサーを設置するコストや労力の削減につながるためである．今回私は，クイーンズ大学ベルファスト校にて間接的手法の研究を行っているDr. McGetrickのもとで，走行車両を使用した加速度計測実験を行った．
【目的】
本ベルファスト訪問の一番の目的は車両走行実験であるが，その他にも英語力の向上，外国人学生との交流，国際学会の公聴といった目的もある．
【実験手法】
実験用車両の後軸上に加速度計を取り付け，車両上部にGPS計測用のアンテナを設置する．これらとは別にスマートフォンを使用して加速度と位置情報を計測し，加速度計，GPS計測器との精度比較を行う．車両フロントガラスからの動画も撮影し，位置情報の補助として使用する．継ぎ手が三ヶ所ある短橋梁上を走行し，継ぎ手部分を正しく検知できるかを確認する．
【実験結果概要】
加速度波形から継ぎ手部で加速度が大きくなっていることが確認され，精度は粗いもののGPSで場所を確認することができた．（Fig.1）
加速度に関しては加速度計の方がスマートフォンに比べて圧倒的に精度が良く，ノイズも少なかった．一方GPSに関してはGPS計測器では計測が途切れることが多かったのに対し，スマートフォンでは一度も途切れることがなかった．これは道路周囲の木々に衛星との通信を邪魔されているからだと考えられる．スマートフォンで計測が切れないのは，GPSだけではなくWi-Fiも利用して位置情報計測の精度を上げているからだと考えられる．
【学生との交流】
クイーンズ大学の研究部屋には，他の様々な国からPhDを取得しに来た学生が在籍していた．彼らから研究内容だけでなく母国の文化の話を聞くことは，貴重な体験となった．また，英語を使わざるを得ない状況下に置かれることで，英語を練習する良い機会となった．Fig.2は現地学生との写真，Fig.3は現地で大変お世話になったDr. McGetrickとの写真である．

Author: Su Danna (D3)
Date: July 24th – July 29th, 2016
Venue: Coex Convention & Exhibition Center, Seoul, Korea
It was a very good opportunity for me to participate in
WCCM XII & APCOM VI (The 12th World Congress on Computational Mechanics & The 6th Asia-Pacific Congress on Computational Mechanics)
held in Korea, and presented my research in a big international scientific meeting.
About 2000 researchers and students from all over the world
with different academic background gathered in the conference.
The title of my presentation was
“Dynamic responses of an urban highway viaduct considering vehicle-bridge interaction under strong earthquakes ”
and presented in the session of “Vehicle-bridge Interaction and Applications”.
The session was chaired by Prof.Yeong-Bin Yang (National Taiwan University/Chongqing University, Taiwan)
and Prof.Zhihai Xiang (Tsinghua University).
After my presentation I have received vital comments and suggestions from prominent researchers in the field.
It is a good feedback for my research and I was motivated by the comment I have received.
I have attended many sessions, plenary lectures during conferences
and had a very good chance to communicate and discuss with excellent students and professors from other countries.
I am very happy to say that it expands my knowledge in the field.
Also I attended the Wiley Workshop,
learned how to select a suitable journal for article publication,
refine paper to increase chances of success, submit a manuscript and survive peer review,
and apply practical techniques to increase the visibility of article after it has been published.
What’s more, I joined Female Researchers Networking Forum,
had a discussion with many female excellent researchers about gender balance in research group,
and how to gain the balance between family and work, and so on.
I would like to appreciate the professors and laboratory

Asia-Pacific-Euro Summer School on Smart Structures Technology (APESS 2016):
Report of attendance
Author: Oscar Sergio Luna Vera (D1)
Date: June 24th – July 13th, 2016
Venue: University of Cambridge, United Kingdom
This year I had the privileged to attend the APESS program
that was held for the first time in the University of Cambridge.
The summer school aims to keep updated engineering graduate students
with the latest advances in smart structure technology and its applications.
Besides, collecting real-time information of structures through sensors
was taught by top-notch professors from around the world
in order to assess the health condition and future management of infrastructure.
I was able to experience the rich academic culture that only Cambridge can offer.
Studying in the place where great minds
like Newton, Darwin, Hawking and many others have been,
keep me motivated to take advantage of the summer program.
In addition, along not only the coursework and laboratory exercises,
but also the trips and social activities carried out,
I had the opportunity to meet several outstanding participants
that at the end of the program became good friends
and with whom I am sure we will follow international collaborative research.

「橋梁の維持管理 実践と方法論」講習会についての報告
文責：五井良直
１． 日時・会場
日時：2016年6月17日（金）13:00～17:00
会場：土木学会 講堂
２． 参加者
五井（D2），河邊（M2），徐（M2），王（M2），三増（B4）
３． 内容
本講習会では主に冊子『橋梁の維持管理 実践と方法論』の趣旨説明が行われた．発表の概略を以下に示す．
13:10-13:25 序論（第I編）
橋梁の維持管理における課題が示され，本講習会の概要が示された．
13:25-14:25 長寿命化修繕計画の実践（第II編）
限られた予算や人材のなかで厳しい状況が続くと考えられる橋梁維持管理の現状について，実態調査の結果が報告された．それらの一例として，本講習会では新潟県および岐阜県における維持管理の取り組みが紹介された．アンケート調査の結果，橋梁管理に携わる職員が他の業務を兼任していることから維持管理に割ける時間が非常に少ない現状などが明らかになった．また，住民が道路施設の不具合を報告できる仕組みづくりなど，効果的な維持管理のための取り組みの事例が紹介された．
13:10-13:25 橋梁点検の実践（第III編）
各事業者が保有する点検マニュアルが収集・分析され，既存のマニュアルの問題点や盛り込むべき技術的内容について検討がなされた．全ての橋梁を画一的に管理するための点検マニュアルを作成することが困難であることが再確認された一方で，点検作業後の診断・評価との繋がりを意識すべきであるなど，点検マニュアルを作成するうえでの包括的な指針が示された．
13:10-13:25 橋梁の維持管理の方法論（第IV編）
Working Groupでの検討結果を踏まえ,ライフサイクルマネジメントの再定義がなされた．また，性能設計の概念に着目してライフサイクルの在り方について検討がなされ，要求性能をその構造物特有の条件に応じて柔軟に対応させる「性能明示型設計」のコンセプトが示された．ライフサイクルマネジメントの事例として，羽田空港のエプロン整備，首都高の大規模更新，長野県におけるライフサイクルマネジメント事例がそれぞれ紹介された．

Asia-Pacific Summer School on Smart Structures Technology (APSS2015) 参加報告書
執筆者...M2河邊大剛
Date: July 26th - August 14th, 2015
Venue: University of Illinois at Urbana-Champaign, United States.
2015年7月26日から8月14日にアメリカのイリノイ大学で
開催されたアジア太平洋スマート構造物サマースクール
（Asia-Pacific Summer School on Smart Structures Technology (APSS2015)）に参加しました．
APSS2015は，世界各国の学生が集いスマート構造技術を学ぶ3週間の
サマースクールプログラムに当研究室から毎年学生が参加しています．
当プログラムに参加し，構造振動制御や先進的センサ技術に関する知見を得ることができました．
それだけでなく言葉の壁と各国の学生のやる気の違いに苦しみながらも
世界中の優秀な学生達と意見を交わしあい発表しあうという経験は，
閉塞的になりがちな普段の研究生活からは決して得られない貴重なものとなり，
自身の研究と将来を考えるうえで重要なものとなりました．
