the longitudinal span is two or more times the short span. In one-way slabs, the short span direction is the direction in which loads get transferred from slab to the beams. Hence the main reinforcing bars are provided along this direction. However, temperature, shrinkage and distribution steel is provided along the longer direction.

PRESTRESSED CONCRETE STRUCTURES

5) Pre stressed concrete allows for a longer span. 6) Pre-stressed concrete members offer more resistance against shear force. 7) Considering same depth of concrete member, a pre stressed concrete member is stiffer than the reinforced concrete member under working loads.
