摘要

摘要: 为研究转动摩擦阻尼器对钢框架的抗震性能的影响,利用有限元软件ABAQUS建立转动摩擦阻尼器有限元计算模型,对结构的抗震机理进行了分析,提出带有转动摩擦阻尼器钢框架结构的恢复力模型,研究了带有转动摩擦阻尼器钢框架结构在单调和低周往复荷载作用下结构的应力分布、破坏模式以及高强螺栓预紧力、摩擦片的摩擦系数对结构抗震性能的影响规律。结果表明,带有转动摩擦阻尼器钢框架的初始刚度及承载力与普通钢框架相比,均得到显著提高,阻尼器达到最大转动量程后与结构协同工作并提供一定刚度;通过增大转动摩擦阻尼器高强螺栓预紧力、摩擦片的摩擦系数可提高结构的初始刚度,但对结构的极限荷载和滑移刚度无明显影响;带有转动摩擦阻尼器钢框架模型的滞回曲线饱满,具有良好的延性和耗能能力。

Abstract: In order to study the seismic performance of steel frame with rotational friction damper parameters, the finite element calculation model of rotational friction damper was established by using ABAQUS. The seismic mechanism of the structure was analyzed, and the restoring force model of steel frame with rotational friction damper was proposed. The stress distribution and failure mode of steel frame structures with rotational friction damper under monotonic and quasi-static load were studied, as well as the influence of high-strength bolt preload and friction coefficient of friction plate on the seismic performance of the structure. The results showed that the initial stiffness and bearing capacity of the steel frame with rotational friction damper were significantly improved compared with the ordinary steel frame. When the damper reached the maximum rotational range, it worked with the structure and provided a certain stiffness; by increasing the preload of high-strength bolts and friction coefficient of friction plate, the initial stiffness of the structure could be improved, but there was no obvious effect on the ultimate load and sliding stiffness of the structure; the hysteretic curve of the steel frame model with rotational friction damper was full and had good ductility and energy dissipation capacity.
