摘要
本文讨论了随机有限元方法近二十年的进展。全文分为独立的两篇，本文为第一篇，其中讨论了随机场的离散，改进的模拟法，随机有限元方程的建立及随机反应各阶矩的计算．
The developments in stochastic finite element methods in recent 2 decades are reviewed in the paper.The paper consists of 2 parts. The part I includes discretization of random fields,improved simulation techniques, formulation of stochastic finite element methods, and computation of moments of structural responses.
