混凝土斜方体抗压有限元分析及试验研究
Finite Element and Experimental Research on Compression of Concrete Trapezoid Body
摘要
Abstract
With the continuous development of cement concrete admixtures, it becomes more and more incomplete to consider only the traditional cube compressive strength as the most important performance indicator. This paper introduces a kind of trapezoid body as the specimen of concrete strength test, and a concept of "compressive strength of trapezoid body ", which considers the effect of complicated stress state under cooperating loads such as pressure, bending, shear on the concrete strength. Finite element analysis and experimental results show that the concrete trapezoid body specimens cracking mainly along the obtuse diagonal under compression; and the damage mechanism of trapezoid body specimens is different from that of cube specimens. Concrete compressive strength of trapezoid body, which reflects material properties of concrete under complex stress state, can be used as another assessment of concrete performance.关键词
