为研究密柱框筒结构中全装配式桁架梁组合楼盖的平面内刚性性能,设计并制作了4个单筒结构的1/3缩尺结构模型(单层、两层框筒模型各两个),通过楼盖平面内单向加载试验,研究了该类装配式楼盖在平行于及垂直于拼装板缝方向受力时楼盖平面内受力变形性能、裂缝开展形态、水平荷载的分配与传递性能、楼盖的平面内刚度及整体变形性能。研究结果表明:在相应于7度罕遇地震的楼层水平力作用下,该组合楼盖在平行于及垂直于拼装板缝方向受力时均处于弹性工作状态;楼盖在平行于拼装板缝方向受力时,受力变形性能与深梁类似,而在垂直于拼装板缝方向受力时,楼盖平面内呈各装配板单元的各自受弯状态,楼盖体系在平...

In order to research the in-plane stiffness performance of a kind of truss beam assembly composite floor (ACF) used in multi-columns bundle tubes structure, four frame models of single-tube with scale of 1/3 were designed (two models for single-story and two-story respectively). Based on the in-plane uniaxial loading experimental study, the in-plane mechanical and deformation performance, development of crack, distribution-transmission performance for floor level force, in-plane stiffness and overall deformation behavior of each floor were discussed and analyzed respectively in the direction o...
