【摘要】 本文通过对2块灌芯混凝土纤维增强石膏板与8个节点构件在低周反复荷载下的抗震性能试验,研究了构件的抗剪承载能力、构件的延性、恢复力特性、耗能能力和破坏特征等特性;通过实测试点工程结构的动力反应,获得结构的自振频率、振型和阻尼比等模态参数。研究表明,该结构在抗震方面具有良好的性能。更多还原

【Abstract】 In this paper,through the experiments of two fiber-reinforced plasterboards filled with concrete and the tests of 8 joints specimens under low cyclic loading,the behaviour of these boards,such as the capacity of shearing force,the ductility features,the hysteretic characteristics,the energy-dissipating capacity and the damage state etc are studied.The natural frequencies,modal shapes and modal damping ratios of the typical structural system are got by dynamic behaviour measurement.It is shown that the structural system has excellent seismic behaviour.更多还原
