Nonlinear structural system identification using shaking table test data of five-story model building

Abstract

The purpose of this paper is to develop an application implementable to a laptop computer by which we can evaluate a structural system from its responses in situ. To show applicability of the application, we analyze the data obtained by a shaking table experiment of a five-story building model. Four Lead Rubber Bearings (LRBs) are placed at the four corner of 1st and 3rd stories of the model building instead of columns to set a clear nonlinear behavior of the structure. Using the test data and the developed application, we identify the dynamic characteristics of five-story building model.
