基于Park恢复力模型,对一榀由角钢混凝土柱和型钢混凝土梁组合而成的单层单跨型钢混凝土框架进行滞回全过程分析,并与试验结果对比。在此基础上对影响此类框架力学性能的主要参数进行考察。结果表明,采用平面非线性程序IDARC-2D能较好的模拟型钢混凝土框架在低周往复荷载作用下的受力全过程,为此类框架的滞回性能模拟提供了合适的方法。
Based on the Park restoring force model, a single-span single-span steel reinforced concrete (SRC) frame composed of SRC columns and steel reinforced concrete beams is analyzed for the entire hysteretic process and compared with the experimental results. On this basis, the main parameters that affect the mechanical properties of such frames are investigated. The results show that using the planar non-linear program IDARC-2D can simulate the whole process of the steel-reinforced concrete frame subjected to low-cycle reciprocating loads, which provides a suitable method for simulating the hysteretic behavior of such frames.
