# 不同荷载形式下HCW耦连比计算Calculation of the Coupling Ratio under Different Load Form of Hybrid Coupled Walls

Abstract: 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.
