Seismic analysis of coupled shear wall systems using probability and random vibration concepts

In modern earthquake engineering, the response spectrum plays a vital role in commonly used methods of analysis for the coupled shear wall systems. Based on the free vibration analysis of coupled shear walls and the mode superposition method of dynamic analysis of coupled shear walls, an approach is presented in this paper for seismic analysis of coupled shear wall systems with the contribution of response spectrum using probability and random vibration concepts. The modified probabilistic and random vibration concepts are employed to determine the mean and standard deviation of the peak response for a coupled shear wall system subjected to earthquake excitation.
