| Abstract: | In dynamic analysis of complicated structure, critical angle of seismic wave is corresponding to critical response of structure. In this paper, based upon superposition principle , the determination of seismic wave critical angle for complicated structures is discussed in detail by using the response spectrum method . An example of the interchange engineering is introduced in this paper. By comparison, the calculating results under different input directions make the seismic responses quite different. |
