ABSTRACT
ABSTRACT The contribution is focused on the numerical simulation of the mechanical response of concrete structural elements loaded in compression and strengthened externally by composite material, specifically Basalt Fiber Reinforced Polymer (BFRP). The constitutive laws defined on the mesoscale for concrete and for the external reinforcement in basalt fiber are discussed. Some details of the numerical solution, including the organization of the computational process and of the finite element model built are reported. Results obtained by finite element analysis are presented: a macro-characteristic of the BFRP-strengthened concrete structural element (i.e., the commonly used stress-strain relationship as well as visualization of the damage initiation and propagation in the concrete.
