集中荷载两对边支承钢筋混凝土板的抗剪强度

Shear Strength of Two-Side Supported Reinforced Concrete Slabs with Local Concentrated Load

本文根据93块板的试验资料,建立了板的抗剪强度计算公式.其形式简单,符合性良好,包括了主要影响因素,适用于各种支承形式(简支的、约束的和连续的).文中还对板的剪力破坏形态和工作宽度进行了论述.

According to the experimental data of 93 reinforced concrete slabs, the authors propose a formula for the calculation of shear strength of slabs. The formula is simple, it considers the main factors, the result is in good agreement with the experimental data, and it may be used for various supports (simple, restrained, and continuous). In this paper, the failure modes of shear and working breadth for shear are discoursed.
