［摘要］为研究钢筋混凝土连梁的变形能力，在已有的连梁试验的基础上，通过理论分析，推导了钢筋混凝土连梁极限位移角与跨高比、剪压比和剪箍比之间的关系，提出了连梁变形能力设计方法。并通过试验结果进行验证，说明了该方法的可靠性。

Abstract: In order to study the deformation capacity of RC coupled beam, base on the coupled beam test, the relationship between drift ratio and span-to-depth ration, shear-compression ratio and ratio of shear to shear resitance were theoretic deduced. A drift-based deformation capacity design method was proposed for coupled beam. The reliability of the method was verified through the test results.

Keywords: coupled beam; deformation capacity; drift ratio; span-to-depth; shear-compression ratio
