| 摘 要： | 为了简便计算带加劲肋的圆孔蜂窝组合梁的强度,应用空腹桁架理论,推导了计入加劲肋影响的圆孔蜂窝钢 - 混凝土组合梁强度简化计算公式.通过算例与ANSYS进行验证,结果表明本文的分析方法是正确的,并建议对剪力分布大的梁段混凝土板内配置受拉钢筋.将计算结果与没有加劲肋的算例梁计算结果进行比较,结果表明,加劲肋可以通过增加计算截面面积来提高蜂窝组合梁承载力.

| Abstract: | In order to conveniently compute the strength of circular hole castellated composite beams with stiffened webs,its simplified formulas were deduced based on the vierendeel truss theory.Then,an illustration was presented.Compared with the results of ANSYS software,the formulas proposed in this article were proved to be correct.This paper further proposed that tensioning steel bars should be collocated in the concrete slab located in the big shear force area.Finally,a comparison was made with the results of c... |
