基于一较完善的大跨屋盖结构有限元模型，采用扰动法、拉丁超立方抽样（LHS）方法进行了多种设计参数对结构自振频率的敏感度分析，并进行了两种方法的比较．结果表明：两方法分析的6种设计参数对结构自振频率的影响规律基本一致．LHS方法考虑参数间的耦合，所得的分析结果较为真实，具有一定的参考价值．

Based on the baseline finite element model of a long-span roof,the perturbation method and Latin Hypercube Sampling （LHS） have been adopted for conducting sensitivity analysis of some key design parameters on natural frequency, and a comparison was made between these two methods. The analyzed results show that the impact law of six design parameters on natural frequency using these two methods are broadly consistent. Coupling between parameters was taken into account in LHS method, the analyzed results obtained from this method are more realistic and have some reference value.
