摘要

采用ANSYS软件,对比研究了异形柱框架结构与矩形柱框架结构的动力特性及在水平地震作用下的弹性地震反应。分析认为,异形柱框架结构与矩形柱框架结构的动力特性差别小;L形柱与对应矩形柱的杆端剪力差别大,而T形、十形柱杆端剪力与对应的矩形柱相差不大;异形柱框架结构的楼层角位移比矩形柱框架结构的楼层角位移略大,但异形柱的扭矩比对应的矩形柱的扭矩要小得多。
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.
