摘要:

基于停车需要,提出了隔层耗能桁架抗侧式立体停车结构,并用有限元法对其中隔层耗能桁架式抗侧力体系在低周往复荷载作用下的性能进行了研究,分析了桁架耗能梁段长度对抗侧力体系的刚度、承载力、延性、耗能性能等的影响。结果表明:随着耗能梁段长度的不断增大,隔层耗能桁架式抗侧力体系的刚度、承载力、延性和耗能性能都存在一定程度的减小和退化; 剪切屈服型隔层耗能桁架式抗侧力体系的耗能性能比弯曲屈服型的要好,但剪切屈服型的耗能梁段也不能设计得太短,否则会影响体系耗能性能的充分发挥。

Abstract:

Based on the requirement of parking, the three-dimensional parking structure with the alternation story-height energy dissipation truss lateral-load-resisting system was presented. The behaviors of the alternation story-height energy dissipation truss lateral-load-resisting system under low cyclic loading were studied by finite element method. Effects of the length of energy dissipation beam within the truss on lateral stiffness, load-carrying capacity, ductility and energy dissipation capacity of the lateral-load-resisting system were investigated. The results indicate that the lateral stiffness, load-carrying capacity, ductility, and energy dissipation capacities will decrease with increase of the lengths of energy dissipation beams. The energy dissipation capacity of shear-yield-typed energy dissipation truss is superior to that of bending-yield-typed one. However, the energy dissipation beam of shear-yield-typed energy dissipation truss should not be too short; otherwise, its energy dissipation capacity will be confined.
