More efficient and industrialised construction methods are both necessary for
thecompetitiveness of in-situ concrete and essential if the construction industry is to …

An analytical model to predict the effective fracture toughness KICs of concrete was
proposed based on the fictitious crack model. Firstly, the equilibrium equations of forces in …

A simple asymptotic analysis dealing with the influence of specimen boundaries on quasi‐
brittle fracture of brittle heterogenous materials is presented. The influence of crack …

Mortar is one of the most widely used civil infrastructure materials, where the mortar fracture
properties will significantly affect the structure service performance and life. In this paper, the …

基于虚拟裂缝模型, 提出一种计算混凝土三点弯曲梁等效断裂韧度的解析方法.
应用该方法计算了梁的最大荷载和临界等效裂缝长度, 进而求得等效断裂韧度. 在此基础上 …

从试件体积为断裂韧度的主要影响因素出发, 进行了12 根相同高度的三点弯曲梁断裂试验,
通过对荷载-裂缝张开口位移曲线和裂缝尖端不同位置处的荷载位移曲线分析, 研究了3 …
