摘要:
大跨度斜拉桥在自然环境中会受到风荷载的作用,而且风对斜拉桥产生的抖振影响不容忽视.通常在分析桥梁抖振前,要计算出风环境状况.本文以斜拉桥为示例,基于经验公式计算分析了主梁尺寸变化对静力风荷载的影响及不同风速下的静力风荷载,并借助Davenport脉动风功率谱,应用谐波合成法模拟计算了斜拉桥在一定风速下的脉动风场.
Abstract:
Long-span cable-stayed bridge will be subjected to wind load in natural environment,and the buffeting effect of wind on cable-stayed bridge can not be ignored.The wind environment conditions are usually calculated before buffeting analysis of bridges.Taken cable-stayed bridge as an example,the influence of main beam size change on static wind load and the static wind load under different wind speeds were calculated and analyzed based on empirical formula,and with help of the Davenport fluctuating wind power spectrum,the fluctuating wind field of cable-stayed bridge under certain wind speed was simulated and calculated by using harmonic synthesis method.
