If the beams are made of the same thickness and cross-sectional dimensions the box beam is twice as strong, vertically and the same strength horizontally. However, if a diagonal force is applied, the box beam could collapse where the I-beam is less likely to do so.
It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
The steel reinforcement used will depend on several factors. Column length, beam length, and the column and beam cross section all depend on how much steel will be needed.
