随着建筑结构及抗震技术的发展,逐渐由传统的方法过渡到针对建筑物的承载和使用能力丧失的可能形式而进行有目的的设计。其实质是试图预见和估计在强震时建筑物承载和使用能力的丧失形式,从 With the development of building structure and seismic technology, the traditional method has been gradually transitioned to a purposeful design aiming at the possible forms of building’s bearing and loss of use capacity. The essence of this is to try to anticipate and estimate the loss of the building’s capacity to bear and use during strong earthquakes.
