| 摘 要： | 首先借鉴传统的基于频域分析的方法,建立从风速谱到风荷载谱的直接关系,通过Monte-Carlo随机变量模拟技术生成高斯模型风荷载.提出了另外一种非高斯模型风荷载模拟方法,并通过实例对两种流程进行了比较,最后依据风洞试验实测数据,对两种流程的适用范围进行了评价. |
| 关 键 词： | 风模拟技术 Monte-Carlo方法 高斯模型 非高斯模型 |

| Abstract: | When using computer to analyze the dynamic response of structure,the method to treat random wind loading is very important,Monte-Carlo method can be used to simulate the random wind loading.With the classic frequency method,the relation between PSD of wind velocity with PSD of wind load is firstly built in this paper and then a series of simulated wind quasi static loading using Monte Carlo method is produces.At the same time,another non gauss method is offered and the two ways are compared.Finally,based on the wind tunnel test,the two models of wind loading are appraised. |
| Keywords: | wind-loading simulation monte carlo method gaussian wind loading non gaussian wind loading |
