钢与混凝土连续组合梁的横向抗剪强度

Transverse Shear Strength of Continuous Composite Beams of Steel and Concrete

本文讨论的是钢与混凝土连续组合梁在负弯矩区段横向抗剪强度,考虑混凝土参加横向抗剪作用,提出一个较合理的横向抗剪强度计算公式,公式的计算结果与实验数据较符合,并认为忽略混凝土参加抗剪作用并非都是偏于安全的。

This paper studies the transverse shear strength in negative-moment regions of continuous composite beams, and prorides a moreresonable strength formula of transverse shear resistance after taking account of the contribution of concrete. The calculation result of this formula shows good agreement with the data of experiments. The study also shows that a neg-lect of the contribution of concrete in the transverse shear strength does not incline to the safe sidc.
