Thus a full scale collapse test of a 4-story steel structure was conducted at the world's largest shake table at the E-Defense facility [2,3]. These tests indicated that it is possible for steel structures to collapse with a first story collapse mechanism when subjected to severe earthquake shaking since columns are not typically
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a ...
