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.
