NUMERICAL INVESTIGATION OF SHEAR BEHAVIOR SHCC STRUCTURAL ELEMENTS

Abstract eng:
Fiber reinforced cement-based composites is a large group of composites with variety of properties. The purpose of adding fibers is to overcome the brittleness of the concrete by improving the postcracking behavior and enhancing ductility. This paper deals with the group Strain Hardening Cement based Composites (SHCC) which exhibits excellent mechanical behavior showing tensile strain hardening and multiple fine cracks. The primary objective of the presented research is to verify a developed constitutive model. The constitutive model is intended to be utilized for large-scale simulations and thus it must be robust and efficient. Therefore, it is necessary to compare the numerical simulations against the experimental data. The paper summarizes the studies performed on the shear behavior of reinforced SHCC elements tested on beam specimens monotonically loaded by an anti-symmetrical moment.
