放大型黏滞阻尼墙的力学性能与试验研究
|
摘要
该文提出一种多杠杆并联的放大型黏滞阻尼墙,根据放大型黏滞阻尼墙的构造和受力特点,分析了放大装置的竖向提拉效应,提出了普通型和放大型黏滞阻尼墙的阻尼力及耗能理论公式,并对装置的变形和耗能进行了分析。设计制作3倍位移放大型装置黏滞阻尼墙和普通黏滞阻尼墙的试验模型,并在正弦波的作用下进行往复加载试验,分析不同试验工况下黏滞阻尼墙的滞回耗能曲线,并将理论曲线与试验曲线进行了对比,验证了力学模型的正确性。在相同位移下,放大型黏滞阻尼墙比普通阻尼墙滞回曲线更加饱满、耗能更为显著。最后以三层混凝土框架结构为计算模型进行减震分析,确认了考虑竖向提拉效应的放大型黏滞阻尼墙的减震效果。
An amplified multi-lever parallel viscous damping wall was proposed. Given its structure and force characteristics, vertical pulling effect, the damping force and energy dissipation theoretical formulas of both common and magnified viscous damping walls were analyzed, as well as its deformation and energy dissipation.An experimental model of both common and magnified viscous damping walls with triple displacements was designed to carry out a reciprocating loading test under the action of a sine wave. The hysteresis curve of viscous damping wall was verified by the comparison between a theoretical curve and the experimental curve under different experimental conditions. Furthermore, the hysteretic curve of the amplified viscous damping wall was rounder than that of a normal damping wall, and the energy dissipation was more significant under the same displacements. Therefore, the three-storey concrete frame structure was used as the calculation model for seismic analysis, which confirms the influence of vertical pulling was effective to the structure of a magnified viscous damping wall.
