中文摘要：
该文首先对PFD-SMA支撑体系的滞回性能进行试验研究,分别研究形状记忆合金长度、Pall型摩擦阻尼器的摩擦力（即滑动螺栓预紧力）对其耗能能力的影响,试验结果表明该体系具有较好的耗能能力,支撑长度、摩擦力对其性能有影响：形状记忆合金支撑长度越短、摩擦力越大,越容易发挥形状记忆合金的超弹性性能。然后将其应用于导管架式海洋平台隔震结构,利用有限元分析软件ANSYS分析平台在地震波下的减震效果,结果表明这种体系具有良好滞回性能,能够消耗较多的能量,能满足安全和稳定性的要求。
英文摘要：
The experimental research on the hysteretic behavior of a Pall-typed frictional damper with shape memory alloy（PFD-SMA） brace system is done. The influence of length of SMA brace and the slip force of the Pall-typed damper are analyzed, and the test results show that the PFD-SMA brace system has better energy dissipation ability, the shorter of the length of SMA and the greater of the slip friction force, the better superelasticity of SMA is showed. Then the PFD-SMA brace system is put in jacket offshore platform isolation layer, the vibration effect of the platform is analyzed subjected to earthquake wave with the finite element analysis software ANSYS. The results show that the system has a good hysteretic behavior, and is able to consume more energy to meet the requirements of security and stability.
