[摘要]  由于鋼筋混凝土異形柱截面幾何性質(zhì)的獨(dú)特性，需要考慮不同地震作用下結(jié)構(gòu)的反應(yīng)。運(yùn)用大型有限元分析軟件ANSYS，對(duì)一棟12層小高層住宅在0°角和45°角的水平地震作用下進(jìn)行模態(tài)分析、反應(yīng)譜分析以及設(shè)防烈度下的時(shí)程分析，研究了鋼筋混凝土異形柱-短肢剪力墻結(jié)構(gòu)的動(dòng)力特性和抗震能力。結(jié)果表明，異形柱方向性較強(qiáng)，在不同的地震作用方向下的受力有較大差異，在一定的剪力墻剛度保證下，結(jié)構(gòu)依舊能在設(shè)防烈度下處于彈性工作階段。

Abstract: Due to the particularity of geometric property of reinforced concrete special-shaped cross-section, structure response in different horizontal seismic directions should be taken into account. The dynamic characteristics and earthquake resistant abilities of the RC frame of short-pier shear wall structure with special-shaped columns in a 12-storey small high-rise residential building under the horizontal seismic loading in the directions of 0 degree and 45 degree are studied in this paper by making modal analysis, response spectrum analysis and time-history through finite-element method analytical software ANSYS. The results show that, the special-column has strong direction, different columns under the different loading direction have a obvious difference，on condition of the enough stiffness of shear-wall, structure can still work in the elastic stage under the fortification intensity.

Keywords: special-shaped column; short-limb shear wall; ANSYS finite-element analysis; horizontal seismic loading
