摘　　要：风荷载对高层建筑动力特性具有较大影响，对于人造脉动风荷载的模拟，现已发展出多种计算方法。本文根据随机振动理论，按照M．Shinozuka方法运用Matlab软件对某一高层建筑顺风向脉动风荷载进行模拟，并编写了风荷载计算程序，由此验证了此种仿真计算方法可以得到未建工程结构风荷载的时程样本曲线，为其凤振控制研究奠定基础，其仿真分析方法具有一定的工程实际意义。There has a great influence on the dynamic characteristics of high-rise building by wind load, and a variety of calculation methods has been developed now for the simulation of artificial fluctuating wind load. In this paper, the along wind fluctuating wind load of a high-rise building is simulated by Matlab software according to M. Shinozuka method on the basis of random vibration theory, andthe wind load calculation program is wrote, which proves that the time history sample curve of the unbuilt engineering structural wind load can be obtained by such simulation calculation method, and which lays the foundation for the wind vibration control research, the simulation analysis method has a certain actual engineering significance.
