Buffeting Analysis for Concrete-Filled Tubular Arch Bridge in Time Domain

摘要: 探讨了利用非平稳随机过程理论和少量的实际风速记录模拟自然风,并以此作为桥址处的自然风用时 域抖振分析方法对某系杆拱桥进行抖振时域分析。通过将计算结果与风洞试验结果的比较,发现二者误差不 大。Abstract: The method using the theory of nonstationary random process and a few real wind-velocity records to simulate natural wind is discussed. Then by taking the simulation results as the natural wind in the bridge address, the buffeting analysis in time domain is carried out for an arch bridge of linking pole. A comparison of the calculated results with those obtained by wind tunnel tests shows little difference between them.
