In order to represent an actual process of structural damage in an actual seismic event and provide a calibration test for numerical studies, a shake table collapse test of a typical multi-story RC frame structural model, which is scaled from a nearly collapsed building in the 2010 Ms 7.1 Yushu earthquake in China, was performed.
Earthquake Shaking Table Structurally, the table may be considered as a 1′ thick diaphragm, stiffened by heavy central transverse ribs that extend below its bottom …
model to predict the real behavior of the damage. NIED use a big scale shaking table facility as in Figure 1.8 to test their ready-made full-scale model. Some of the specifications of the shaking table facilities are; Shaking table type : 3D Full scale earthquake testing facility Payload : 1200 ton Shaking table size : 20m x 15m
Boundary conditions can significantly affect a slope's behavior under strong earthquakes. To evaluate the importance of boundary conditions for finite element (FE) simulations of a shake-table experiment on the slope response, a validated three-dimensional (3D) nonlinear FE model is presented, and the numerical and experimental …
This paper introduces a large scale shake table experimental program on bridge structures using E-Defense. The program was formulated as one of the US-Japan cooperative research programs based on NEES and E-Defense collaboration. Component model (C1 model) and system model (C2 model) are included in the program.
A previously designed and fabricated friction damper with four piezoelectric actuators was installed on the first storey of a quarter-scale, three-storey building model mounted on a shake table. The performance of the damper and a simple semi-active control strategy were evaluated both numerically and experimentally under four modified ...
