摘要
在海洋平台摇摆墙体系基础上,在摇摆墙底部的铰接点处安装一粘弹性转角阻尼器,进行被动消能结构振动控制,利用ANSYS进行地震荷载作用下的抗震性能验算,并对阻尼器的刚度和阻尼参数进行了分析。结果表明,在摇摆墙底部施加的转角阻尼器能显著降低结构的地震反应。
Based on the offshore platform-rocking wall system,we installed a viscoelastic rotary damper in the hinge point at the bottom of the rocking-wall for passive energy dissipation and structure vibration control.The seismic performances are calculated by using ANSYS software under the earthquake load,and the stiffness and damping parameters of damper are analyzed and compared.The results show that the rotary damper is installed at the bottom hinge of the wall can significantly reduce the seismic response of structures.
