为研究LRB消能墙设置在高层框架结构中的隔震、消能与减震的效果,采用有限元分析软件ETABS对LRB消能墙高层框架结构的实际工程进行三维结构模型建模,同时对相同规模的框架剪力墙结构进行三维结构模型建模,在2组实际强震地震波El-Centro波和Taft波以及1组人工波作用下,对上述2种结构形式的三维结构模型进行动力性能分析并作比较。结果表明,相对于传统的框架剪力墙结构,LRB消能墙高层框架结构的自振周期能有效延长,LRB消能墙高层框架结构的楼层加速度、楼层剪力最大值以及层间位移得到明显的降低,并使楼层加速度和层间位移变得平缓均匀,从而达到隔震、消能与减震的目的。
In order to study the effect of isolation, dissipation and damping of LRB energy dissipating wall set in high-rise frame structure, the three-dimensional structural model of LRB energy dissipation wall high-rise frame structure was modeled by using finite element analysis software ETABS, The three-dimensional structural model was modeled with the same size of frame-shear wall structure. Two groups of three-dimensional structural models with the above structural forms were subjected to dynamic performance under the action of El-Centro waves, Taft waves and 1 set of artificial waves. Analyze and compare. The results show that the natural period of high-rise frame structure of LRB energy dissipation wall can be prolonged effectively compared with the traditional frame-shear wall structure. The acceleration of floor, the maximum value of shear force and the displacement between floors of high-rise frame structure of LRB energy dissipation wall are obviously And make the floor acceleration and layer displacement become even and even, so as to achieve the purpose of isolation, energy dissipation and damping.
