|Prof. Koju Ikago‘s visit |
On September 20, 2018, Prof. Ikago of Tohoku University visited the Department of Civil Engineering in Tsinghua University, and gave a presentation about tuned viscous mass damper .Prof. Ikago and Prof. Ji introduced their latest research about TVMD. In the end, Prof. Ji discussed his research plan about TVMD with Prof. Ikago and other audience.
|Dr. Rolands Kromanis‘s visit |
On September 3, 2018, Dr. Rolands of Nottingham Trent University visited the Department of Civil Engineering of Tsinghua University, and gave a presentation titled "Characterizing and interpreting thermal response of bridges and Measuring structural deformations using smartphones". Professors Xiaodong Ji, Zhang chonghou, Zhao zuozhou and postgraduates of the Department of Civil Engineering of Tsinghua University participated in this presentation and discussed the related contents with Dr. Rolands. The lecture is comprised of two parts, and Dr. Rolands introduced us to some of his achievements in the field of structural health monitoring. In the first part, based on the nonlinear regression model, Dr. Rolands proposed the regression-based thermal response prediction methodology of bridge structure. The effectiveness of the method is verified by experiments. The application is demonstrated in multi-span continuous beam bridge for damage detection. The second part of the lecture focused on the displacement measurement method based on smartphone images and videos. Examples of the method on static, quasi-static and dynamic tests are presented, and application of real-world bridges for displacement monitoring is illustrated. In addition, a study of multi-epoch imaging approach to collect accurately structural displacements when capturing images of a structure from different positions is introduced.
|Prof. Carlos Molina Hutt‘s visit |
Prof. Carlos Molina Hutt from the University of British Columbia visited Prof, Ji’s research group on July 11th 2018. Prof. Carlos Molina Hutt gave a presentation based on his research about the evaluation of post-earthquake recovery ability for structures. The contents about how to quantify expected seismic performance, evaluate strategies for enhanced seismic performance and benchmark performance against modern designs were introduced. And a possible extend framework beyond individual building evaluations was discussed. Prof. Ji’s group members introduced their latest research, discussed with Prof. Carlos Molina Hutt and got many valuable suggestions.
|Workshop of Advancement & New Technologies in Earthquake Engineering |
An international symposium was held to introduce the recent advancement and new technologies in earthquake engineering developed by each individual presenter. The main objective of this symposium is to enable the project members to be familiar with each other, to understand the ongoing research for each other, and to expand future broad collaboration. Approximately 40 researchers and students from Tsinghua University and IEM participated in this symposium. Adequate discussions were observed among the presenters and audiences. The workshop was held successfully in achieving its objective.
|Prof. Okazaki, Prof. Takahashi, Prof. Marino's visit |
A seminar was held to introduce the ongoing research of Prof. Ji's group. Three research topics were presented. 1) Mr. Xiaowei Cheng (Ph.D. student) and Mr. Mengchao Xu (master student) presented the complicated behavior of RC shear walls subjected to combined tension, bending and shear loads. 2) Mr. Junshan Zhang (master student) and Mr. Yuhao Cheng (Ph.D. student) presented the development of an innovative shear wall system for enhanced seismic resiliency of high-rise buildings. The new system is named tuned viscous mass damper (TVMD) coupled wall system. 3) Dr. Sanjukta Chakraborty (postdoctoral researcher) shared her latest work on development of control algorithms for substructure shaking table tests. During the seminar, Prof. Okazaki, Prof. Takahashi and Prof. Marino kindly delivered their comments and suggestions to the presenters for these ongoing studies.
|Seminar of image processing & performance evaluation |
The team members from both China and Japan sides held a technical discussion with the theme of "Rapid Post-Quake Estimation of Structural Damage and Performance Based on Modern Image Processing Technology". The key words of the meeting were image processing and performance evaluation. Mr. Zenghui Miao (a Ph.D. student of Prof. Ji) presented his work on “Damage evaluation of RC structural components based on modern image processing and deep learning”. Dr. Xiaoting Wang (a postdoctoral researcher in Prof. Pan’s group) presented the latest work on new Chinese code drafting on resilience assessment of buildings, including assessment procedure and the software for calculation of repair cost and time. Prof. Takahashi gave a brief introduction on the researches of his group. Afterwards, the participants discussed research ideas and technical difficulties of the imaging processing, crack quantification, damage identification and performance evaluation. The PEER-Hub competition of imaging-based damage identification was discussed as well.
|Doctor Rick Henry's visit |
Doc. Rick Henry from the University of Auckland visited the Department of Civil Engineering, Tsinghua University on April 18, 2018. He gave a comprehensive and wonderful presentation titled “Design of Seismic Resilient Concrete Buildings in New Zealand”. The presentation provided an overview of recent earthquakes in New Zealand and key lessons from these earthquakes. This talk also presented test research and design practice to achieve low-damage concrete buildings (e.g. Post-tensioned rocking wall). At last, Prof. Rick Henry shared the design details of Post-tensioned rocking wall (e.g. wall-to-floor connection, wall-to-column connection). Doc. Rick Henry will take part in Prof. Ji's reasearch on the axial tesion-shear coupled behavior of RC shear walls in the future.
