Center of Structural Monitoring and Control

SHMC is sharing a benchmark problem based on a real bridge with the SHM community. This benchmark problem has completed recently. The data used in this problem were collected by an in-situ structural health monitoring system implemented into a full-scale cable-stayed bridge before and after the bridge was damaged, which is very rare in structural health monitoring field.

With Prof. Hui Li’s gracious invitation, Prof. Tadanobu Sato, an Emeritus Professor of Kyoto University, now is a professor of Southeast University, will visit the Center of Structural Monitoring and Control (SMC), School of Civil Engineering at HIT from Apr 16th to 18th. He will make a presentation at Dec 17th. We sincerely welcome the interested faculties and students to join in the seminar activities.

Topic of “Physical meaning of earthquake motion phase and its modeling to simulate response spectrum compatible design earthquake motions” by Prof. Tadanobu Sato

Tuesday, Apr 17th, 2013

14:30-16:30

Room: 402, School of Civil Engineering

Abstract:

Performance Based Seismic Design is the seismic design methodology with a rather new concept. Performance Based Seismic Design allows the design team to work together to determine the appropriate levels of ground motion and Performance Objectives for the infrastructures in order to meet the owner’s expectations. Almost all current seismic design codes, such as not only U.S. and Japanese but also other international ones, only have recommended using typical observed earthquake motion phases to check seismic performance of the designed structure. And almost all researches have paid attention only to the non-stationary characteristics of amplitude spectrum and less interest in the phase spectrum. The importance of earthquake motion phase has been pointed out many times bur so far no proper modeling of earthquake motion phase has been proposed yet. We has been studying to develop a method to simulate design earthquake motion for more than two decade, and has also contributed to model the phase spectrum using fractal characteristics of the Fractional Wiener Process (FWP) and group delay time recently. Through this we will develop a new and innovative simulation method of non-stationary time history such as the design earthquake motion using the fractal characteristic of earthquake motion phase based on FWP.

Prof. Tadanobu Sato is an Emeritus Professor of Kyoto University. Now he is a professor in the International Institute for Urban System Engineering at Southeast University. He earned his bachelor's and master's degrees, as well as Ph.D., in Civil Engineering from Kyoto University. His primary research interests include dynamic constitutive relationship of soil (1978-1986), non-linear soil-structure interaction problem (1971-2005),  non-linear seismic response of surface ground (1975-2005),  seismic response analysis of surface ground with irregular soil profile (1977-2005), identification and simulation of earthquake motion  (1979-), damage estimation of lifeline systems (1980-), optimal control of seismic response of structural systems (1988-2001), health monitoring of structure systems (1986-), simulation and modeling of earthquake motion for design code  (1972-), education on disaster mitigation (2006-), quantification of socio-disaster problems (2006-).

On December 31st, 2012, SMC held a banquet to celebrate the coming of new year. Among the 100 plus attended the banquet were faculty members, their families and students. Prof. Hui LI made 2013 New Year's Speech and extended the SMC’s heartfelt festivity greetings and best wishes to all faculty members, their families and students.
