针对某高层建筑结构,利用ETABS有限元分析软件建立计算模型,探讨原结构和设置黏滞阻尼器的减震结构在多遇地震作用下的抗震性能,通过进行五种黏滞阻尼器布设方案下结构响应的比较,以不同的控制函数为目标,进而优化黏滞阻尼器的布设位置。结果表明,黏滞阻尼器在保证不增加结构刚度的基础上,通过提供附加阻尼,能有效协助结构耗散地震输入的能量,降低了结构的动力响应,起到了很好的减震效果。同时,在考虑黏滞阻尼器的布设位置时,应根据结构的实际动力响应和变形特性综合确定,并且考虑结构的功能需求以获得最佳的减震效果。
Aiming at the high-rise building structure, the calculation model is established by using ETABS finite element analysis software to study the seismic performance of the original structure and the viscous damper with damping structure under the action of the earthquake. By means of five viscous damper layout schemes The comparison of the structure response, with different control functions as the goal, optimizes the layout of the viscous damper. The results show that the viscous damper can effectively assist the structure to dissipate the input energy of the earthquake and reduce the dynamic response of the structure by providing additional damping on the basis of not increasing the structural rigidity, thus achieving a good damping effect. At the same time, taking into account the layout of the viscous damper should be based on the actual structure of the dynamic response and deformation characteristics of a comprehensive determination, and consider the functional requirements of the structure in order to obtain the best damping effect.
