摘　　要：中高层生态复合墙混合结构体系是一种生态环保、节能节地、耗能减震、能够快速建造的新型建筑结构体系,主要由预制的生态复合墙板、混凝土竖向约束构件、暗梁及楼板装配现浇而成。以带边框墙体的抗震性能试验研究为基础,分析得出墙体具有多道抗震防线即"砌块—框格—竖向约束构件";并利用数值软件ABAQUS对各道防线影响因素进行扩展分析,分别研究:第1道防线不同内填砌块对其的影响;第2道抗震防线中肋梁尺寸、肋柱尺寸、肋梁配筋、肋柱配筋对其的影响;第3道防线中竖向约束构件配筋对其的影响。研究表明:砌块、框格结构及竖向约束构件三道不同防线之间相对强度、相对刚度的匹配是三道抗震设防实现的有效保证;中高层生态复合墙混合结构三道防线的具体形式可以根据结构不同性能水准的高低,或者具体设计要求因地制宜地选择,满足使用者的个性化要求。As a new kind of structure system, middle-high ecological hybrid composite wall structure is ecological, environmental, energy-saving, and has the advantage of energy dissipation and vibration reduction.Besides, it can be built rapidly.The system is mainly composed of prefabricated concrete vertical constraint components, hidden beam and assembly cast-in-place floor slab.The results indicated that under horizontal load, block, sash and frame could interact, and bear loads together.They played a role in turn in elastic stage, elastic-plastic stage and failure stage of the test.This made the middle-high ecological composite wall end up with multiple seismic lines “block-sash-vertical constraint component”.On the basis of experimental study, the finite element software was used to analyze the influence factors of each line of defense, the effect of block strength for the first defense line, the size of the rib beam and frame column, the reinforcement of rib beam and rib column for the second defense line, the reinforcement of vertical constraint component for the third defense line.According to numerical analysis the influence rules of different factors were summarized which provided theory support for the later engineering practice.Studies showed that the matching between the relative strength and relative stiffness of different defense blocks, grid structures and three vertical restraint members was the effective guaranteed to realize three seismic lines.The seismic design method of the middle-high ecological composite wall hybrid structure on the basis of three seismic lines could satisfy the personalized requirements of the performance goals design in structure.
