摘要:
为了明确单斜杆偏心支撑框架结构体系的传力路径和内力分配,便于计算层间侧移和耗能连梁转角,采用结构力学方法给出了单斜杆偏心支撑框架结构在侧向力作用下的耗能连梁剪力和支撑轴力表达式,依据小变形假定和胡克定律,推导出了单斜杆偏心支撑的弹性抗侧刚度,通过30个算例分析表明:弹性抗侧刚度计算公式误差仅为10%左右;耗能连梁剪力和支撑轴力计算公式具有较高的精度,可用来确定构件的弹性内力,并提出了支撑斜杆的简化设计方法
Abstract:
In order to identify loading path and internal force distribution of single sway rod eccentrically braced steel frames(‘SSR-EBF’
in brief)andcompute story driftsand link rotationsconveniently, the formulas of elastic axial forces of brace and shear force of link
subjected to lateral loads have been proposed based on the fundamental assumption of structural mechanics, and then the elastic lateral
stiffness formula of SSR-EBF is put forward on the basis of the small deformation assumption and Hooke’s law. The analysis
results of 30 examples indicate that, the error of elastic lateral stiffness formula is approximate 10%, and the accuracy of formulas of
internal force is sufficiently. The simplified design method of brace rod is suggested.
