By using the finite element method with consideration of time factor, the vertical differential shortening and member internal forces of steel frame-reinforced concrete corewall structures were analyzed. The studies show that the amount and the involvement time of concrete shrinkage and creep are determined by the time parameters in construction scheme, which change the effect of concrete shrinkage and creep obviously. To reduce the effect of shrinkage and creep, it is a good method to appropriately increase the number of floors of concrete corewall before the steel frame is constructed.
