This research aims to study experimentally behavior of hybrid deep beams when subjected to two point's monotonic and repeated loading in presence or ence of web openings.
All tested deep beams have the same reinforcement in flexural (ρ= 0.0184) and web (ρw=0.003) and same dimensions of (1500mm length, 150mm width and 350 mm height).
In this research, the idea of hybridity was achieved by reinforcing the two shear spans with steel fiber keeping the middle span free from this fiber.
The aim was to strengthen shear wings against shear failure (diagonal strut failure).
To achieve the aim, twelve deep beams were cast and tested.
Six of them were tested under monotonic loading as control beams to the other six beams tested under repeated loading at levels of 55% of the ultimate load of their control beams.
The variables attempts were: loading type (either monotonic or repeated), beam type (either hybrid or non-hybrid), steel fiber (SF) ratio, and finally web opening sizes.
The results illustrate that the ultimate load of deep beam with web openings under monotonic loading increases as the SF ratio increases.
When SF was added to shear spans with a ratios of 1% and 2% under monotonic loading system, the ultimate load percentages increase are 37.5% and 68.75% , respectively compared with ultimate loads of beams which are without SF.
Also, using fiberous concrete in casting the entire length of beams leads to an increase in the ultimate load of 4.55% as compared with deeps beams with the same SF ratio of 1% , and 43.75% as compared with beams cast with conventional concrete.
The results using different opening size of square shapes, it was found that the ultimate load decrease as size of web openings increases from 0.61% of beam size to 1.37% of beam size by 10.17% and 25.42% , respectively as compared with hybrid deep beam without This research aims to study experimentally behavior of hybrid deep beams when subjected to two point's monotonic and repeated loading in presence or ence of web openings.
