【提要】  采用ANSYS軟件，對(duì)比研究了異形柱框架結(jié)構(gòu)與矩形柱框架結(jié)構(gòu)的動(dòng)力特性及在水平地震作用下的彈性地震反應(yīng)。分析認(rèn)為，異形柱框架結(jié)構(gòu)與矩形柱框架結(jié)構(gòu)的動(dòng)力特性差別?。籐形柱與對(duì)應(yīng)矩形柱的桿端剪力差別大，而T形、十形柱桿端剪力與對(duì)應(yīng)的矩形柱相差不大；異形柱框架結(jié)構(gòu)的樓層角位移比矩形柱框架結(jié)構(gòu)的樓層角位移略大，但異形柱的扭矩比對(duì)應(yīng)的矩形柱的扭矩要小得多。

Contrastive Analysis of Mechanics Characteristic Between Specialshaped and Rectangular Column Frame Structures/Ke Jiang, Gao Duixian(Xi'an University of  Technology,Xi'an 710048,China)
Abstract:The dynamical characteristic  and elastic seismic response   of specialshaped column frame structure and rectangular column frame structure  under horizontal earthquake action are contrastively analyzed   through  ANSYS program.Some conclusions are reached: there is little difference in the dynamical characteristic between the two frame structures，and great difference is existed in poleend shearingforce between Lshaped column and rectangular column.However, the poleend shearingforce of Tshaped column and crisscross shape column is not discrepant comparing to corresponding rectangular column. The floor angular displacement in specialshaped column frame structure is larger than that in rectangular column frame structure, while the torsion moment in specialshaped column is much less than that in rectangular column.
Keywords:specialshaped colomn; frame structure; dynamical characteristic; earthquake response
