摘要
结构响应的随机性主要有两个原因:一是载荷的随机性,这是通常的随机响应分析;二是结构参数的随机性。为了保证结构设计的可靠性,设计工程师必须知道结构参数的随机性对结构响应的影响。本文提出计算一类随机参数结构响应的统计特性(均值与标准差)的一种有效的方法,并给出了数值例子来说明此方法的实际应用。
The randomness in the response of structures is due to two primary factors.One is the randomness in the load,which has been discussed extensively in the past.The other is the randomness associated with structural parameters.To insure reliability of a design,design engineers need to know the effect of the randomness in the structure on the response.In this paper,a practical and effective method to calculate the response statistics,mean values and standard deviations of random structures,is presented.As the application of this method,a numerical example is presented.
