摘　　要：　根据墙肢和连系梁之间的变形协调条件,用能量法研究了高层建筑结构双肢变厚度剪力墙的整体稳定问题.所提出的临界荷载计算公式简单,易于应用,可适用于墙厚和连系梁高度均发生变化的各种情况.算例分析表明,计算结果和其他方法的计算结果吻合较好.According to the deformed coordination of walls and coupling or connecting beams,the method of energy is applied to study the gravity buckling loads of coupled shear wall in tall buildings. Approximate formulas established for the buckling loads are rather simple and can be applied to walls with changes in thickness and to coupling beams in varions heights. Numerical examples are compared with results obtained by other methods and their good agreement is demonstrated in the paper.
