摘　　要：以轻骨料混凝土梁体为主要研究对象,系统试验了梁体在震源下的受力情况、破坏机制、滞回曲线、刚度退化、骨架曲线等能力,同时利用有限元ABAQUS建立模型,并模拟计算出上述各个机制的模拟结果,通过结果计算对比得出试验计算得到的滞回曲线、破坏形态等和有限元分析计算的结果基本吻合,同时也证明了轻骨料混凝土梁体结构可以在低周期反复荷载作用下工作。Based on the lightweight aggregate concrete beam as the main research object,system test the force of the beam body under the source,the failure mechanism,hysteresis curve and stiffness degradation.Skeleton curves such as ability,at the same time,using the finite element model of ABAQUS,and calculate the various mechanisms of simulation results,through comparing analysis of the results,it is concluded that the finite element simulation of hysteresis curves,and the failure pattern,were in good agreement with the test results,but also proved that the lightweight aggregate concrete beam structure can work under low cycle load.
