【提要】  对钢筋混凝土异形柱框架结构抗震性能的研究尚未形成一致的结论。通过对现有研究成果的比较可以发现，这类结构的变形能力介于钢筋混凝土矩形柱结构和剪力墙结构之间，其弹性层间位移角限值应以控制填充墙的墙面裂缝贯通为判断标准，弹塑性层间位移角的取值应当既有一定的保证率，又要符合工程实际，建议取1/75比较合适。

Abstract:No unified conclusion about the seismic performance of RC frame structure with special shaped column is chieved.Based on the analysis of all present researches,it shows that the deformation capacity of the RC frame structure with special shaped column is higher than that of the shear wall structure while lower than the RC frame structure.The elastic allowable deformation value is determined based on the norm that the cracks interpenetration of the filled wall should be controlled.The elastoplastic allowable deformation value should accord with the practical engineering,and the value of 1/75 is suggested.
