新型球型钢支座耗能减震元件试验研究与数值模拟

open access: yesJianzhu Gangjiegou Jinzhan
在万向减震球型钢支座的基础上对其弹簧元件进行耗能设计,提出了一种新型耗能减震球型钢支座,采用钢板弹簧叠加耗能钢作为耗能减震元件。通过单调拉伸加载试验和循环拉伸加载试验,研究了Q295钢材的耗能能力,采用拟静力试验和数值分析相结合的方法,分析了支座耗能减震元件的滞回性能和自复位性能;将该新型球型钢支座应用于网架结构中,考察其耗能减震能力。研究结果表明,Q295钢材的滞回曲线饱满,具有一定的耗能能力;减震元件的耗能减震性能较好,并且具有一定的复位能力;相较于一般的弹性减震支座 ...
