摘要
分析了K. J. Willam等提出的五参数混凝土破坏准则存在的问题,提出了一个改进了的五参数混凝土破坏准则.这个准则克服了K. J. Willam等的准则的主要缺点,简化了偏斜截面的表达式.准则包含的参数确定方便,与实验数据符合良好,是一个比较合理的适合钢筋混凝土有限元分析采用的混凝土破坏准则.
The five-parameter failure criterion of Willam and Warnke is analyzed. Based on the results. an improved five-parameter failure criterion for concrete is presented. This new criterion has the advantages of W-W criterion, while avoiding its disadvantages. The expression of the deviatoric section is greatly simplified. The parameters in this criterion are easy to be determined and good agreement exists between this criterion and experimental results. Therefore, it is a good failure criterion to be used in finite element analysis of reinforced concrete.
