摘要

通过对三根小跨高比剪力墙连梁在低周反复荷载作用下的试验,了解了严格按《高层建筑混凝土结构技术规程》(JGJ3-2002)设计的连梁具有的抗震性能,研究了采取增大连梁配箍量同时加强纵向构造筋的方案对抗震性能的影响,并进一步对新的配筋形式的连梁进行了探讨,了解了在连梁梁端配置多排交叉斜筋方案对连梁抗震性能的改善。通过对试验现象的观察和量测结果的分析,最后得出结论。
In this paper, based on the experiments of three short coupling beams under the reversed long cyclic loading, the seismic ductility of the coupling beams which are strictly designed by the code of Technical specification for concrete structures of tall building(JGJ 3-2002), was found out and the influence of the increase in stirrups besides the strengthening of longitudinal detailing reinforcement on the coupling beams was studied. Then the coupling beams with new reinforcement layout were further delved, and the improvement on the seismic behavior of coupling beams diagonally reinforced with a few rows in end regions was found out. At last, based on the observation of the experimental phenomena and the analysis of the measurement results, a conclusion is presented.
