Dynamic Collapse Analysis of the Six-Story Full-Scale Wall-Frame Building

In order to simulate the collapse process of a six-story full-scale wall-frame building tested at E-Defense in January 2006, analytical studies were carried out before and after test. In the preliminary analysis, the effects of analytical model characteristics, shear-span to depth ratio of short column and torsional response on seismic behavior of a specimen were investigated. And after test, numerical simulation of the experimental response was conducted by modeling the behavior of each frame with different kinds of models, which are characterized by the capability of simulating strength degradation. Simulated results showed that the observed strength-degrading feature in post-peak region could be reproduced from the analytical models employed in shear critical members such as short column and shear wall.
