The common construction methods of simply supported beam bridge mainly include cast-in-place construction and precast installation construction. According to the construction technology, simply supported concrete beams can be divided into two categories: integral and assembled (split). Its advantages are simple structure, convenient installation, reduced cost and shortened construction period, and it is also the easiest to design various standard span assembled components.

Simply Supported Beam Bridge: A simply supported beam bridge is a beam whose two ends are supported on movable bearings and hinged bearings respectively as the main load-bearing structure. It belongs to statically indeterminate structure. It is the earliest and most widely used beam bridge. Its structure is simple and easy to erect, and its internal force is not affected by foundation deformation and temperature change.
