[摘要]鋼筋混凝土連梁為耗能構(gòu)件,我國規(guī)范要求樓面梁不宜支承在連梁上。在實際工程中為了避開連梁,通常需要將樓蓋梁布置成斜梁,導(dǎo)致施工不便,不利于房間分割及設(shè)備布置。然而工程中存在連梁支承樓面梁的需求。為解決這一難題,提出一種新型可支承樓面梁的分段式鋼筋混凝土連梁,兼具承重和耗能雙重功能。結(jié)合工程實例,對直梁方案和斜梁方案進(jìn)行綜合比選,并利用ABAQUS對分段式連梁的抗震性能進(jìn)行詳細(xì)分析。分析結(jié)果表明,在地震作用下,采用分段式連梁可以兼具承重與耗能的雙重功能。

Abstract: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.
Keywords:frame-corewall structure; segmentation coupling beam; energy dissipation and bearing; seismic performance
