【摘要】 预应力叠合结构集装配式与现浇式结构优点于一体，对这种体系的研究我国从20世纪60年代就开始了，至20世纪90年代，对叠合框架结构在竖向单调荷载下的性能研究取得了许多成果，得到了有益的结论。但预应力叠合框架结构在水平反复荷载下的性能研究还没有，这自然是个空缺。本次研究正是针对这个原因，采用对比试验分析的方法，探讨了两榀预应力叠合框架和一榀对比现浇框架在水平低周荷载下的抗震性能，证实了预应力叠合框架与现浇框架的抗震性能相当，极限承载力也接近，也分析了叠合框架柱不同于整浇框架柱受力变形特征的原因，并提出了有效的构造措施。同时，为落实科学研究成果要尽快转化为生产力的要求，我们在湖南省建设厅的支持下，首次在湖南把预应力叠合楼盖技术应用到工程实际中(长沙天龙大酒店，22层)，取得了可喜的经济效益和社会效益，本文将设计施工中的要点与方法也一并整理，对高效预应力叠合技术的推广应用具有重要意义。更多还原

【Abstract】 Since 1960s prestressed concrete composite structures that have advantages of both assembly and cast-in structure have been researched. By 1990s composite frame under vertical monotonous load has been studied, and corresponding results have been concluded. But, if any, little study has been fulfilled on the seructure under lateral low-cyclic and reverse loading. In this paper experimental study on seismic behavior of the frame is conducted using the contrast tests including two models for prestressed composite frames and one for reinforced concrete frame. Based on the test results, the seismic behavior of performance concrete composite and reinforced concrete frames is studied. Effective construction measurements of the structure are provided as well. In order to have the research results applied to real projects, in some proposals about the design and construction for this kind structure have been presented.更多还原
