摘　　要：网壳空间结构广泛应用于大型公共建筑中,它具有柔性大、质量轻、阻尼小、自振频率低的特点,属风敏感结构,因此对此结构进行风振响应分析很有实际意义。现有的风振响应分析方法大致分为三种,时域法、频域法以及随机振动法。通过对某一网壳工程应用各种不同的分析方法进行算例分析,计算中心各杆件的轴力和位移来比较各种方法的优缺点,为以后的计算选择提供参考。Space reticulated shell structures are widely used in large public buildings. It shares the characteristics of weak stiffness,light weight, small damping and low frequencies. This kind of structure is sensitive to the fluctuating wind. so it is of great practical significance to study wind vibration response of this structure. The analysis method of wind-induced response can be divided into three kinds, the time domain method, frequency domain method and the random vibration method. An example is given through the analysis of different methods of a shell engineering, axial force and displacement of bar members are calculated, advantages and disadvantages of various methods are compared, so the reference can be provided for the calculation for the future engineering design.
