摘要
在2个短肢剪力墙无粘结预应力楼盖子空间结构模型的低周反复加载试验研究基础之上,通过有限元分析,补充研究这类结构顶层端节点在不同水平配箍量条件下的受力性能,及梁端竖向箍筋部分进入节点区的受力性能,并对顶层端节点的水平箍筋用量,提出了设计建议。
In this paper, bassed on revered cycle loading tests on the two specimens of concrete structures with short shear wall and unbonded tendons prestressed slab, it analyzes the behavior of this concrete structure system under cyclic loading by finite element analysis. At first it studies mainly the bearing seismic capacity under different level stirrup, rate and beam stirrup in four top story knee joints for the concrete structure system. At last, it brings forward the quantity of level stirrup for top story knee joint.
