【提要】  對鋼筋混凝土異形柱框架結(jié)構(gòu)抗震性能的研究尚未形成一致的結(jié)論。通過對現(xiàn)有研究成果的比較可以發(fā)現(xiàn)，這類結(jié)構(gòu)的變形能力介于鋼筋混凝土矩形柱結(jié)構(gòu)和剪力墻結(jié)構(gòu)之間，其彈性層間位移角限值應(yīng)以控制填充墻的墻面裂縫貫通為判斷標(biāo)準(zhǔn)，彈塑性層間位移角的取值應(yīng)當(dāng)既有一定的保證率，又要符合工程實際，建議取1/75比較合適。
【關(guān)鍵詞】  異形柱  框架結(jié)構(gòu)  層間位移角限值
Study on Allowable Values of Story Drift for RC Frame Structure with Special Shaped Columns/Zhang Wei1,Liang Xingwen2(1 Hongkong Huayi Designing Consultants Ltd.,Shenzhen 518045,China; 2 Xi'an University of Architecture & Technology,Xi'an 710055,China)
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.
Keywords:special shaped column;frame structure;allowable value;story drift
