Abstract:

Both engineering applications and theoretical analysis of the transfer-storey structures are generally limited in elastic stage under frequent earthquakes; the structural behavior after yielding under serious earthquake need to be studied by elastic-plastic analysis. And there is no specific method which confirms that transfer structures can “resist serious earthquake without collapse”. In this research, the doctrine of capacity design is show the design of transfer-storey structures and a method of practical design for transfer structures under serious earthquake. By push-over analysis, many limit states of coupled shear walls are disclosed. Parameters that possess significantly the structure behavior such as integer coefficient of coupled shear walls, height-width ratio of shear walls and reinforcement ratio of coupling beams are highlighted. The shear overstrength of the coupling beams under limit state is decrease with the reduction of K coefficient. Overstrength of shear walls is born by ultimate state analysis, which considers the axial forces increment of shear walls caused by overstrength of coupling beams. On this condition, capacity based seismic design method of transfer storey under serious earthquake are analyzed by elastic-plastic analysis. The simplified formulas and the detail procedure for capacity design of transfer structures are described in brief.
