摘要

Abstract

A simple and effective random polyhedral aggregate model was developed for micromechanical analysis of concrete. Through introduction of three random variables and two control parameters, the ellipsoid was translated into irregular polyhedron. The irregularity of aggregate was controlled by two parameters and the shape and sharp of ellipsoid were controlled by the property of ellipsoid. Examples showed that the random polyhedral aggregate model can reflect various graded aggregates in actual project and provide sufficiently accurate results for concrete inhomogeneity studies.
