ABSTRACT

In the present work, a non-linear finite element (FEM) analysis has been conducted in order to investigate the performance strengthening of reinforced self-compacting concrete T-deep beams with rectangular openings by CFRP sheets. five beams have been considered with different opening location (size of openings 150 *250)mm. To improve the performance of beams with rectangular openings, the most commonly used methods in strengthening have been adopted which is CFRP sheets. This comparison was based on the of load-deflection curves, ultimate loads and cracking patterns the result obtained are compared with those experimentally recorded at failure. The comparison result between the results of the experimental program and the F.E. analysis showed the validity of the result model adopted in the present work to simulate the behavior of the flange deep beams have openings strengthening by CFRP sheets in the present work. The analysis results showed that when the introducing openings with size of (150*250) mm led to a reduction in the load capacity by ( 64%) when located flushed to the flange and (70%) when bottom location.
