Structural Time History Response Analysis of Bidirectional Seismic Input

Abstract:

In this paper, 6 eccentric structural models are selected as examples, a great many elastic earthquake response analyses are carried out. The biggest action effect which an earthquake brings about when acting in one direction along certain angle is found out, and is defined as a normal value. Simultaneously, the present two commonly used methods using bidirectional horizontal earthquake input, with identical horizontal component earthquake waves, are used to calculate effect value. The results are compared, and they indicate that it's suitable for the proportion of the two component earthquake acceleration peak values to be adjusted to 1:0.3，when carrying out the bidirectional horizontal earthquake input with the same earthquake wave.
