| Summary: | This study examines the flexural behavior of six hybrid composite castellated beams with varying castellated degrees (25%, 33.8%, and 50%). Hybrid beams are formed by utilizing plates with different strengths in the compression and tension zones. Three hybrid composite castellated specimens fabricate from half of IPE200 on the bottom and half of IPE160 on the top while the other three hybrid beam fabricate from a half of IPE200 on the upper and half of IPE160 on the bottom. Two symmetric concentrated load were delivered at the third places to the six specimens. It can be seen from the tested beams that the bearing amount decreases by (12% and 37%) with increasing the percentage castellation to (33.8% and 50%) for beams with a noticeable decrease in deflection. Strength augmentation in hybrid beams can be accomplished by incorporating low yield strength steel in the upper T-part of the beam and high yield strength steel in the lower T-part, when under load. |
