Abstract

This chapter presents a comparison between the results of experimental and numerical analyses of concrete block prisms under compression loads. The main goal of this research is to simulate the nonlinear mechanical response of the prisms, based on the behaviour of blocks and mortar joints, using a numerical non-local damage model specifically developed for quasi-brittle materials. An experimental program, with simple compression tests with displacement control, was carried out to determine the damage parameters for the individual components to characterize the numerical model. Two- and three-block prisms were also tested in simple compression to obtain their complete load-displacement characteristics to failure. Despite the simplicity of the experimental procedure, the results show that the damage model employed is able to predict the strength of the prisms reasonably well and their behaviour in the softening regime.
