摘　　要：提出了一种模糊输入特征的楼面反应谱计算方法。文章主要由以下三部分组成:(1) 建立考虑设计地震(震中烈度、影响烈度和震中距离)和场地(土层剖面和场地类别)特征模糊性的模糊地震输入;(2) 以具有模糊参数的平稳随机过程为基础,利用振型分解法求解楼面反应谱;(3) 用例题展示了所建议方法的计算过程。A randomized calculation method of floor response spectrum in consideration of fuzzy characteristics of input motion is presented in this paper. The contents of this paper are composed of three parts: 1. Establish random seismic input in which the fuzziness of the design earthquake (epicentral intensity, felt intensity and epicentral distance) and site condition (soil layer characteristics and site category) are incorporated; 2. Search the solution of floor response spectrum by using of mode superposition method based on the stationary random with fuzzy parameters; 3. Illustrate the computation procedure of the suggested method by examples.
