| 摘 要： | 实腹式型钢混凝土短柱是型钢混凝土组合结构的主要承重构件。目前,我国规程依据试验统计建立实腹式型钢混凝土短柱的受剪承载力计算公式,往往不考虑型钢翼缘的影响。本文采用桁架-拱模型理论对实腹式型钢混凝土短柱的受剪承载力进行了分析,将实腹式型钢混凝土短柱分为钢筋混凝土与型钢两部分考虑,然后将两部分叠加从而求得。分析钢筋混凝土部分的受剪承载力时,采用桁架-拱模型,考虑了型钢腹板和翼缘的影响;型钢部分的受剪承载力取Va=(0.58f_at_wf_w)/(λ-0.2)。本文计算结果与试验结果吻合较好。

| Abstract: | The solid-webbed steel reinforced concrete short column is the main load-bearing part of steel reinforced concrete composite structure.In China,the related formula is built on the experimental results,often without taking the impact of steel shape flange into account.This paper explored the shear bearing capacity of solid-webbed steel reinforced concrete short column based on trussed arch model,in which solid-webbed steel reinforced concrete short column includes steel reinforced concrete and steel shape.Th... |
