本文提出了一种新型耗能支撑。静力试验表明,耗能支撑能耗散大量地震输入能,它的恢复力特性曲线是弹塑性曲线,并且支撑中应力始终保持在弹性范围内。它能反复加载很多次。动力试验表明,由于耗能支撑滑动荷载不变,它的顶点最大加速度反应同地震大小及其频率特性无关。这种支撑能经受1.53g水平振动而不坏,并能安全通过共振区10秒钟以上。它的动力反应比普通支撑小很多,因此该耗能支撑是比较理想的抗震结构。
This paper proposes a new type of energy-consuming support. The static test shows that the energy-consuming support energy dissipates a large amount of seismic input energy, and its recovery force characteristic curve is an elastic-plastic curve, and the stress in the support is always kept within the elastic range. It can be loaded repeatedly many times. The dynamic test shows that the peak acceleration response of the apex is independent of the size and frequency characteristics of the earthquake because of the constant energy consumption supporting the sliding load. This support can withstand 1.53g horizontal vibration without damage, and can safely pass through the resonance zone for more than 10 seconds. Its dynamic response is much smaller than ordinary support, so this energy-consuming support is an ideal seismic structure.
