Numerical validation of compressive strength prediction for hollow concrete blocks
The results of a numerical modeling program to evaluate the behavior of hollow concrete blocks under uniaxial compression are addressed. It has been considered appropriate to use interface elements to represent the confinement effect at the top and bottom of blocks. The response of the numerical simulations is compared with experimental data of masonry units. Laboratory tests were carried out utilizing standard flat platens and brush platens to evaluate the confinement effect due block geometry. The elastic and inelastic parameters compressive strength, tensile strength, stress-strain relationships and fracture energy were acquired from concrete samples that constitute the blocks. The results from the theoretical analysis are discussed with respect to the ability to reproduce the experimental tests. Good agreement between experimental and numerical results was found for the peak load.
