本文在充分利用钢板屈服耗能器性质稳定、耐久性好等优点的基础上,针对 X形钢板屈服耗能器中存在的薄膜效应,结合 Pall摩擦耗能器独特的构造特点,提出了工程可用的组合钢板屈服耗能器,并进行了这种耗能器的滞回特性试验和疲劳性能试验。试验结果表明,组合钢板屈服耗能器与消除了薄膜效应的 X形钢板屈服耗能器的性能相似。最后通过地震模拟振动台进行了高层钢结构模型的减振试验,试验结果表明组合钢板屈服耗能器对地震位移反应有良好的控制效果,对加速度反应也有一定的控制作用。
In this paper, based on the advantages of stable performance and good durability of the yield insulator of the steel plate, in view of the thin film effect existing in the yield insulator of the X-shaped steel plate and the unique structural features of the Pall frictional energy absorber, Of the combined steel yielding energy device, and the hysteresis characteristics of the energy dissipater and fatigue properties of the test. The experimental results show that the performance of the composite steel yielding energy dissipater is similar to that of the X-shaped steel yielding energy dissipater with no film effect. Finally, the vibration test of the high-rise steel structure model is carried out by the seismic simulation shaking table. The experimental results show that the yield energy dissipator of the composite steel plate has good control effect on the seismic displacement response and also has a certain control effect on the acceleration response.
