- Synopsis:
- A simplified procedure for single-story asymmetric building subjected to bi-directional ground motion is proposed. In this procedure, their responses are predicted through a nonlinear static analysis of MDOF model considering the effect of bi-directional excitations and an estimation of the nonlinear response of equivalent SDOF model. The results obtained by the proposed procedure are compared with the results obtained by the nonlinear dynamic analysis performed for simultaneous bi-directional ground motions. Their results are compared with the nonlinear dynamic analysis results, and satisfactory prediction can be found in nonlinear response of single-story asymmetric buildings.
