Material model for non-linear finite element analyses of large concrete structures

A fully triaxial material model for concrete was implemented in a commercial finite element code. The only required input parameter was the cylinder compressive strength. The material model was suitable for non-linear finite element analyses of large concrete structures. The importance of including a crack closure algorithm was demonstrated on a...

Investigation of v min based on experimental research

This paper presents an experimental research program aiming at assessing the current code provisions of vmin. A large test series was carried out, by varying the reinforcement ratio and loading conditions, the minimum average shear stress that can cause shear failure of a specimen with different depth, concrete strength is determined. The three...
