摘要
根据结构可靠性优化中概率约束函数的不同类型，分别提出了将概率约束等价显式化处理的３ 种方法：分布函数法、可靠性安全系数法和分离函数法．通过等价显式化处理，使原可靠性约束从形式上转变为常规约束，为基于可靠性的结构优化设计提供了方便．两个实例表明了这种方法的可行性和有效性．
According to the function types of probability constraint in structural optimization based on reliability, three equivalent treatment approaches by displaying probability constraints are proposed. Through the equivalent treatment, the original probability constraints are changed into conventional constraints in form. Two examples show that these proposed approaches are feasible and efficient.
