摘要
为研究钢结构连廊在人致荷载下的动力特性,文中以洛阳理工学院九都校区钢结构连廊为研究对象,采用Midas Gen有限元软件以4种不同的工况对连廊结构进行时程分析,以舒适度双控标准对结构的动力响应进行评价。结果表明连廊的竖向自振频率大于3 Hz,4种工况下的峰值加速度均小于0.15 m/s^(2),满足规范限值要求。研究为设计者提供了一种评价结构舒适度的方法,也为类似工程结构的舒适度分析提供参考。
A steel structure corridor is taken to investigates the dynamic features of the corridor under human-in⁃duced loads.Midas Gen finite element software is utilized to perform time course analysis of the structure under four distinct work conditions.Furthermore,the structure's dynamic response is assessed via the dual-control criterion of comfort degree.The results indicate that the corridor's vertical self-oscillation frequency exceeds 3 Hz,and the peak acceleration remains below 0.15 m/s^(2) under all four working conditions,thereby satisfying the prescribed limits.This assessment method equips designers with a means to evaluate the structural comfort and serves as a reference point for similar engineering undertakings.
