Experimental Study On The Effect Of Web Opening Location On The Behavior Of Reinforced Concrete Hybrid Deep T-Beam Subjected To Pure Torsion âVarious Location In Vertical Direction

ABSTRAK Three reinforced concrete hybrid deep T-beams with circular web openings were tested under pure torsion. The beams were cast of normal weight concrete (NWC) webs and light weight concrete (LWC)flanges. The opening was placed at beam mid span. The main parameter considered in this study was the location of web opening in vertical direction. The results show that generally all beams give no significant difference in torque strength, twist capability and torsional stiffness.
