| 摘 要： | 完成了6个跨高比分别为1.0、1.5、2.0和2.5对角斜筋连梁试件的低周反复加载试验,分析了该类连梁的裂缝发育及破坏、延性、刚度退化以及滞回耗能性能等。结果表明,适当配筋的对角斜筋连梁具有比普通配筋连梁更好的抗震性能,可在剪压比为0.20的条件下达到不低于3.5的弦转角延性以及良好的耗能性能。在经试验识别的受力性能基础上提出了小跨高比对角斜筋连梁以主斜拉杆-压杆模型和箍筋桁架模型作为主要传力体系的受力机理。

| Abstract: | Low frequency cyclic loading experiments are carried out with six diagonally crossing reinforced coupling beams.The ratio of the span to depth is 1.0,1.5,2.0 and 2.5.The paper analyzes the behavior of crack development,failure mode,ductility,stiffness degeneration,hysteretic and energy dissipation of these specimens.The results show that the aseismatic behavior of properly reinforced diagonally cross reinforced coupling beams is better than conventionally reinforced coupling beams,and this kind coupling bea... |
