Load Capacity of Curved-up Beams
Keywords:
Curved-up, Straight, Beams, Camber, Load capacityAbstract
Straight and curved-up beams are cast as part of portal frame models. The models are made as single-span, double-span, and triple-span models. Experimental investigation is conducted to predict load capacity of curvedup beams compared to straight beams. Load was applied onsite using traditional load application. The enhancement of load capacity of a curvedup beam compared to straight beam is predicted. The enhancement in load capacity is predicted for single-span, double-span, and triple-span portal frame models is presented.
