高震区框架结构的薄弱层变形验算

Discussion on the check computations of deformation of frail layer of frame structure in high vibration areas

针对现行结构设计规范中没有明确给出高震区框架结构薄弱层验算具体方法的情况,从规范给定的条件入手,通过对大、小地震下弹性、弹塑性位移角限值关系的推导和对比,提出了在高震区框架结构薄弱层验算中进行参数修正的方法。

Aimed at the present code of structure design without the specific method of frail- layer check computations of frame structures in high vibration areas, this article provides the parameter modifying method for the checking according to different regulations of earthquake parameter and by deducing and contrasting the relation of elasticity and plasticity displacement angle limitation of several earthquakes from the given conditions of present code.
