Research On The Seismic Design Of Transfer-Storey Structures Based On Philosophy Of Capacity Design Under Severe Earthquake
Jack CHEANG Han Xiaolei  Tang JianQiu   Chen Xuewei

ABSTRACT :
Both theoretical analysis and engineering applications of the transfer-storey structures are mostly limited in elastic stage under frequent earthquakes; the structural behavior after yielding under severe earthquake need to be studied by elastic-plastic analysis. And there is no specific and quantitative method to ensure that transfer structures can “resist severe earthquake without collapse”.  In this paper, the philosophy of capacity design is introduced into the design of transfer-storey structures and a practical design method for transfer structures under severe earthquake is presented. Through push-over analysis, various limit states of coupled shear walls are disclosed. Parameters that influence significantly the structure behavior such as integer coefficient of coupled shear walls, reinforcement ratio of coupling beams and height-width ratio of shear walls are highlighted. The shear overstrength of the coupling beams under the ideal limit state is reduced with reduction coefficient K. Overstrength of shear walls is derived by ultimate state analysis, which considers the axial forces increment of shear walls caused by shear overstrength of coupling beams. On this basis, mechanical characteristics and capacity based seismic design method of transfer storey under severe earthquake are studied by elastic-plastic analysis. A series of nonlinear dynamic time-history analysis has been completed, which considers the influence of varied parameters including the stiffness and mass of transfer structures, seismic protected intensity and the position of transfer storey. Moreover, the simplified formulas and the detail procedure for capacity design of transfer structures are presented.
