摘要
基于中国《公路桥梁抗风设计规范》,采用谐波合成法并考虑了桥梁风场的空间相关性,结合M atlab语言编制了谐波合成法程序,模拟了一大跨悬索桥梁的脉动风场,其模拟结果与目标谱之间拟合较好,说明了谐波合成法对该桥梁风场模拟的有效性。
Based on the Wind-resistant Design Specification for Highway Bridge of China,the harmonic synthesis program is prepared by combining with Matlab language and a stochastic fluctuating wind field of a long-span suspension bridge is simulated by harmonic synthesis method with the consideration of spatial correlation of the bridge wind field.Its simulated result is well fit to the target spectrum,which proves that the effectiveness of harmonic synthesis method to the wind field simulation of this bridge.
