[摘要] 在研究含模糊参数的网架结构随机地震反应分析中，对于模糊参数的表达是通过模糊集的分解定理或扩张原理来进行的，这种传统的方法比较复杂。本文采用信息熵理论，将模糊结构转化为随机结构进行动力分析，给出了一种新的研究模糊网架结构的随机地震反应分析方法。实例证明，采用信息熵方法分析模糊网架结构的随机地震反应是可行的。

Abstract: The method of fuzzy truss structures dynamic problem is given. In study random earthquake analysis of fuzzy truss, it ever hardly described fuzzy equation because its theory is based on decomposition theorem and extension principle. The way of information entropy and transform the fuzz to random problem is used, and it is possible to solve the random earthquake of the fuzzy truss through this method.
