| 摘 要： | 本文处理一类重要的工程问题：不确定性结构的弹塑性分析，分析模型包含了一类分片线性的硬化法则，这包含了大范围实际观察所得的材料特性。我们所处理的不确定性是由荷载及材料参数引起的。本文先把问题转化为一个随机非线性规划问题，然后用逼近技术给出一个简单的求解方法。

| Abstract: | This paper deals with an important engineering problem, namely the elastoplastic analysis of structures under uncertainty.The analysis model incorporates a class of piecewise linear hardening laws that are sufficiently general to encompass a wide range of practically observed material behavior. The uncertainty we deal with is due to both loads and material parameters. We first formulate the problem as a stochastic nonlinear programming problem and then propose a new simple method for solving it via some approximation techniques. |
