| Abstract | ||
| This paper presents experimental work includes investigation of seven composite modified reactive powder concrete (MRPC) I- beams, 1300mm length, 100mm web width and 320mm height, with and without opening tested under pure torsion. The first beam was the control beam without steel plate and the second beam was solid with steel plate and the five of these beams were cast as composite beams and opening in web. The main variable was the location, shape and size of opening in web .The experimental results show that the web opening decreases the ultimate torque of composite beams in the range of 17.6% to 30.8% for the tested specimens.as well as the results show that the used steel plates increase the ultimate torque of composite beams by 7.7%. | ||
