Simply-supported beams have supports under their ends which allow rotation, but not deflection.

We impose simply-supported boundary conditions and zero initial conditions.

A method for calculating the longitudinal shear capacity of the slab of simply-supported steel–concrete composite beams is presented.

Deflections in rectangular, fully fixed-ended spanning members are 1/3 to 1/5 those of simply-supported members for the same uniform loads, stresses and spans.

In order to provide the maximum structural efficiency and constructibility, the simply-supported girders were placed on the abutments and piers, while projecting reinforcement was embedded into the concrete support-diaphragms.
