Failure Dependence of High-Rise Frame Shear-Wall Structures under Frequently Occurred Earthquakes and Its Application

Junfeng Zhu, Yifan Li, Qun Mei


In order to simplify calculation of structural system reliability, it is necessary to study failure dependence of structure. In this paper, failure dependence of high-rise frame shear-wall structure is studied based on interstory deformation under frequently occurred earthquakes. From the analytical results, some useful laws of failure dependence are obtained. The failure between the layers of high-rise frame shear-wall structure is neither fully independent, nor entirely relevant under frequently occurred earthquakes. The failure relevant number accounts for half the total number of high-rise frame shear-wall structure. The failure relevant layers concentrate on the upper part of high-rise frame shear-wall structure. Structural system reliability is calculated base on failure dependence. It is feasible to calculate structural system reliability considering the failure of interstory deformation as main failure modes, and the calculation of structural system reliability can be greatly simplified.
