Efficient viscous energy dissipation prestressed frame
The invention discloses an efficient viscous energy dissipation prestressed frame. Two sets of frame columns are vertically arranged in parallel; the prefabricated upper frame beam and the prefabricated lower frame beam are arranged between the two groups of frame columns in parallel up and down; the prestressed tendons are arranged in the prefabricated upper frame beam and the prefabricated lower frame beam respectively, the two ends of each prestressed tendon penetrate out of the corresponding frame columns respectively, and the two sets of frame columns are tightly pressed at the two ends of the prefabricated upper frame beam and the two ends of the prefabricated lower frame beam. The lower wall plate and the viscous energy dissipater are mounted on the top surface of the prefabricated lower frame beam; the top end of the rigid lever is hinged to the center of the bottom of the prefabricated upper frame beam through an upper pin shaft, the middle of the rigid lever is hinged to the upper middle portion of the lower wall plate through a middle pin shaft, and the bottom of the rigid lever is hinged to the output end of the viscous energy dissipation device through a connecting rod. The displacement magnification times of the viscous energy dissipaters can be flexibly adjusted by changing the position relation of the upper pin shafts, the middle pin shafts and the connecting rods, and the viscous damping force can be adjusted by increasing or decreasing the number of the viscous energy dissipaters.
本发明公开了一种高效粘滞消能预应力框架，框架柱具有两组，竖直平行布设；预制上框架梁和预制下框架梁上下平行布设在两组框架柱之间；预应力筋分别内置在预制上框架梁和预制下框架梁中，且每根预应力筋的两端分别从对应框架柱中穿出，将两组框架柱压紧在预制上框架梁和预制下框架梁的两端；下墙板和粘滞消能器安装在预制下框架梁的顶面；刚性杠杆的顶端与预制上框架梁的底部中心经上销轴相铰接，刚性杠杆的中部与下墙板的中上部经中销轴相铰接，刚性杠杆的底部与粘滞消能器的输出端经连接杆相铰接，通过改变上销轴、中销轴、连接杆的位置关系可灵活调整粘滞消能器的位移放大倍数，通过增减粘滞消能器的数量，可调整粘滞阻尼力的大小。
