Abstract:

This paper introduces a harmful drift angle transfer storey. Based on numerous sample analyses of to control the lateral stiffness of high-rise structures with high-rise buildings with transfer storey and by considering the effects of various different kinds of structures and different shear wall thicknesses, an appropriate harmful drift angle ratio of no more than 0.9 is put forward as the control criterion of the lateral stiffness of high-rise buildings with transfer storey. Moreover, by employing a finite element model, the influences of such factors as the inter-storey shear wall stiffness, the transfer beam stiffness and the storey height on the harmful drift angle calculated by the link model are analyzed. Thus, a modified harmful drift angle ratio method is obtained. Some suggestions are also made for engineering applications.

Key words: transfer storey, high-rise building, lateral stiffness, harmful drift angle
