不同荷载形式下HCW耦连比计算

Abstract

混合连肢剪力墙(HCW)是采用钢连梁代替传统钢筋混凝土连梁的一种结构。文章提出了通用于双肢和多肢剪力墙的耦连比概念，即耦连比表示连梁剪力产生的总约束弯矩与结构外部水平荷载产生的倾覆力矩的比值。文章推导出了均布荷载、倒三角形荷载和顶点集中荷载形式下耦连比的计算公式。实际工程计算表明，与传统方法相比，该计算方法更加简便、准确，为后续研究提供了基本参考。 Hybrid Coupled Walls use steel coupling beams instead of the traditional reinforced concrete beams. We put forward the general concept about coupling ratio in both double shear walls and multiple shear walls. It presents the proportion of system overturning moment produced by the structural external load resisted by the total constraint bending moment produced by shear forces of coupling beams. We also deduced the calculation formula of coupling ratio under uniform load, reverse triangle load and concentrated load. Actual engineering calculation showed that, compared with the traditional method, this calculation formula is more simple and accurate. This study provides a basic reference for subsequent research.
