摘要:
通过3个理想化模型(理想弹脆性模型、理想弹塑性模型和理想软化模型),对新近提出的一种计算混凝土韧性的方法——裂后强度方法(Post Crack Strength method, PCSm method)进行了讨论,阐述了PCSm方法合理的一面,同时也说明了PCSm方法的不足之处,并针对其缺点提出了2种改进方法.
Abstract:
Through three idealized model (ideal elastic-brittle model, ideal elastic-plastic model and ideal softening model), Post Crack Strength method, which is a measure of energy absorption capacity of concrete, was discussed. This paper expounds the rationality of PCSm method and point out its limitations. At the same time, the paper also proposes two alternate techniques for discussion.
