THE CRACKING STRENGTH OF ARTIFICIAL-INDUCED JOINT IN MASS CONCRETE

摘要：

Based on double-G fracture energy theory,an improved model of cracking strength for artificial-induced joint in mass concrete are presented in the paper,in which the coupling effects of size,boundary and concrete strength etc. on cracking strength are considered. Based on Hamiltonian theory of elasticity,a series of crack singular analytical elements in the vicinity of artificial-induced joint tip are constructed. Implemented the hyper-elements into ordinate finite element system,a kind of semianalytical finite element method (FEM) for many cracks like artificial-induced joints in plane pate is constructed using bilinear cohesive force distribution. The comparisons of numerical results with experimental data,together with the predictions given by the present model prove that the work of the paper is efficient and accurate.
