梯形波纹钢腹板的剪切强度

波纹腹板用于提高钢梁腹板剪切稳定性,同时避免横向加劲。研究梯形波纹钢腹板的剪切强度,总结了以往梯形钢腹板的剪切强度公式及相应理论。提出新的剪切强度公式,考虑不同剪切失效模式的相互影响。根据相关试验的试件参数,对100多个试验结果进行整理和分析。大多数试验条件都与剪切强度公式中的理论条件假定不一致。将这些公式与试验进行对比,结果表明:新公式更精确。

Shear Strength of Trapezoidal Corrugated Steel Webs

Corrugated webs are used to increase the shear stability of the steel webs of beams and girders and to eliminate the need for transverse stiffeners. This paper focuses on the shear strength of corrugated steel webs with trapezoidal corrugations. Previously developed formulas for predicting the shear strength of steel trapezoidal corrugated webs, along with the corresponding theory, are summarized. A new formula is developed, which considers interaction among the various shear failure modes. More than 100 te...
