摘　　要： 钢筋混凝土连梁为耗能构件,我国规范要求楼面梁不宜支承在连梁上。在实际工程中为了避开连梁,通常需要将楼盖梁布置成斜梁,导致施工不便,不利于房间分割及设备布置。然而工程中存在连梁支承楼面梁的需求。为解决这一难题,提出一种新型可支承楼面梁的分段式钢筋混凝土连梁,兼具承重和耗能双重功能。结合工程实例,对直梁方案和斜梁方案进行综合比选,并利用ABAQUS对分段式连梁的抗震性能进行详细分析。分析结果表明,在地震作用下,采用分段式连梁可以兼具承重与耗能的双重功能。 Reinforced concrete coupling beams are energy dissipation members. According to Chinese code,coupling beams are not suitable for supporting floor beam in engineering. However,inclined beam floor structure is usually used to avoid coupling beam,which also has some problems,such as inconvenience of construction,room segmentation and equipment layout. Actually,demand of coupling beam for supporting floor beam is abundant in engineering. In order to solve this difficult problem,a new segmentation reinforced concrete coupling beams for supporting floor beam was proposed with double functions as energy dissipation and bearing. Combined with practical engineering,straight beam scheme and inclined beam scheme were compared and seismic performance of segmentation coupling beams was analyzed in detail by ABAQUS. The results show that segmentation coupling beam has double functions as energy dissipation and bearing under the earthquake.
