等面积异形柱与矩形柱多层框架的结构性能对比分析
Contrast analysis on structure performance of multi-story frames with equal-area special shaped columns or rectangular columns
摘要
Abstract
In order to study the effect of using special-shaped column and rectangular column on the structure performance under the condition of equal cross section area of columns,combined with a six layer frame residential buildings,the structure design software SATWE is used for the structure design of special-shaped column frame structure and rectangular columns frame structure.In the two kinds of structure,section area of both special-shaped column and rectangular column in the same location is equal.The seismic performances of the two kinds of structures under seismic load are analyzed,such as interlayer displacement angle,floor maximum displacement,floor shear,shear-weight ratio,natural vibration period,vibration mode, etc.According to the specification,three seismic waves are chosen for elastic and elastic-plastic time history analysis of the two kinds of structure respectively using software SATWE and EPDA.The economy is also analyzed from the perspective of the amount of reinforcement steel bar.Analysis results show that when section area of frame column is equal,special-shaped column frame structure has better seismic performance than rectangular columns frame structure,but the economy is a bit poor.The study results provide theoretical reference for the special-shaped column and rectangular column selection under different conditions.关键词
