Comparison between Experimental and Numerical Structural Behaviour Results of Concrete Cube Models

Abstract

This research is aimed to compare between experimental and numerical values of axial deformation and compressive strength of 12 concrete cubes. The numerical concrete models were analyzed using computer software (UDEC) and (Phase2).The concrete mix was prepared according to the British standard specifications. The 12 concrete cubes were classified in to four groups, each group consists of 3 models that were tested at 7, 14, 21and 28 days respectively by compressive machine to obtain the values of axial deformation and compressive strength. It was found that concrete cubes which crushed at 7 day gave high values of axial deformation and low values of compressive strength. After 28 days the axial deformation were reduced to 57.7% and compressive strength increased by 78.6% in comparison with concrete cubes at 7 days It was found that, the difference between experimental and numerical values of axial deformation was about 4.6%. in comparison with concrete cubes at 7 days It may be concluded that, the computer software UDEC and Phase2 can be used for simulation of concrete models to obtain the axial deformation and compressive strength.
