摘　　要：本文基于SATWE软件,针对实际工程中一个多层RC框架结构的斜交异形构件,分别采用等效柱截面方法(C法)和抗震墙方法(W法)建立结构模型,进行整体结构抗震计算和对比分析。分析表明,对于斜交多层RC框架结构,可采用SATWE软件综合考虑C法和W法对结构进行包络设计,并根据结构位移曲线及底层框架的剪力和倾覆力矩的比例等指标综合判定结构类型。若结构属于少墙框架结构,除斜交异形构件外的其余构件的内力及配筋,宜采用C法的计算结果;对于斜交异形构件,可按抗震墙对其进行截面设计。Aiming at a specially shaped oblique component of a multi-storey RC frame structure,based on SATWE software,equivalent column section method and seismic wall method are respectively adopted to establish the structural model,and the seismic calculations and comparatively analysis of the overall structure are carried out. The analysis shows that in terms of oblique multi-layer RC frame structure,the SATWE software should be employed to envelope-design the structure by equivalent column section method and seismic wall method,and the structure types can be determined based on structural displacement curve and some indicators of underlying framework like the ratio of shear force and overturning moment. When the structure is a less wall frame,equivalent column section method should be used to calculate reinforcement and internal force of models except specially shaped oblique component,while the specially shaped oblique component can be properly designed as seismic wall by equivalent column section method.
