STUDY ON SEISMIC BEHAVIOR OF COMPOSITE FRAME WITH SRC COLUMNS AND STEEL BEAM
-
摘要: 通过2榀钢骨混凝土柱-钢梁框架的低周反复荷载试验,对钢骨混凝土组合框架的滞回性能、延性、耗能性能、刚度衰减等抗震性能进行研究。并依据JGJ 1382001《型钢混凝土组合结构技术规程》及YB 90822006《钢骨混凝土结构技术规程》计算组合框架的极限承载力。结果表明,钢骨混凝土柱-钢梁框架结构具有良好的抗震性能,两部规程的计算方法均有较高的精度。Abstract: Based on experiment of two pieces of frames with SRC columns and steel beam umder low-reversed cyclic loading,hysteresis behavior,ductility,energy dissipation and rigidity degeneration are studied. The ultimate loading capacity of the composite frame is calculated,by the provisions in JGJ 1382001 Technical Specification for Steel Reinforced Concrete Composite Structures and YB 90822006 Technical Specification of Steel-Reinforced Concrete Structures. The study results show that the frame with SRC columns and steel beam has better seismic performance and accurate results can be got by the methods of the two specifications.
