【摘要】 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。更多还原

【Abstract】 This paper suggests a new type energy dissipating bracing (EDB). Static test shows that EDB can dissipate a great deal of earthquake input, energy and its restoring force is an elastoplastic one. Besides, the stresses of the bracing are always within the elastic range. It can be repeatedly loaded many times. Vibration test shows that the maximum acceleration response at the bracing top is not related to earthquake magnitude and its frequency characteristics since its sliding force remains unchanged. It has endured 1.53s base horizontal vibration without any damage and can pass resonance zone safely for more than ten seconds. Its dynamic responses are much less than those of ordinary bracings, and therefore EDB is a rather ideal earthquake resistant structure.更多还原
