The dual seismic resistant structure system is proposed, and its design strategy is discussed. A practical example of dual resistant system building endured in the 1995 Kobe earthquake is introduced. Experimental researches of a new type shear wall, designed according to the dual seismic resistant concept, is undertaken to make out detail seismic behaviors. Based on nonlinear dynamic analysis of single degree freedom system, the design parameters are studied.
Keywords: dual seismic resistant structure; design strategy; earthquake; nonlinear dynamic analysis
