【摘要】 在结构方案和结构荷载确定后,影响框架柱截面尺寸的控制因素主要为轴压比限值、层间位移角限值和剪压比限值。在结构设计中,可先进行框架柱截面尺寸估算,并判定框架结构抗震等级,然后通过PKPM软件试算,根据相应的控制因素限值进行框架柱截面尺寸修正,可取得更佳的技术经济指标。更多还原

【Abstract】 The controlling factors of section size of frame columns are axial compression ratio and story drift angle and shear compression ratio. In the design process,section size of frame columns should be estimated and aseismic grade of the frame structure should be determined firstly. And trial calculation is performed by PKPM. And then section size of frame columns are updated according to the corresponding limited value of controlling factors. By above method,better technical and economic indexes are obtained.更多还原
