摘　　要：连梁在剪力墙结构或核心筒结构中通常被设计成抵抗地震的第一道防线,因此在工程中应避免将连梁设计成脆性破坏。然而在实际工程中,由于需要满足建筑结构的功能需求,常常将连梁设计成小跨高比连梁,小跨高比连梁的抗剪承载力低,在强震中容易发生剪切破坏,本文将就小跨高比连梁的抗震性能的优化方案进行讨论,为设计及研究人员提供参考。Coupling beams are always designed as the first line of defense against earthquake in shear wall structure or core tube structure.Therefore,the coupling beams should not be designed to the brittle failure in engineering.However,in practical engineering,because of the need to meet the functional requirements of building structure,coupling beams often designed to small span-to-depth ratio.The small span-to-depth ratio coupling beams have low bearing capacity of shear,they are easy to be shear damaged in strong earthquake.This paper will discuss the aseismic performance optimization scheme of small span-to-depth ratio coupling beam,and provide reference for the designer and researcher.
