Box Girder Bridge Construction Sequence Sample Plans PDF

As its name implies, a segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then transported to their final location for placement in the full structure). The sequence of construction is similar to traditional concrete bridge building, i. The example bridge has a two-cell box girder with the depth varying parabolically from 16 ft at the piers to 7 ft at mid span and abutments. The input for the algorithm is the description of the cross-section, the longitudinal profile, the sequence of segmental construction, the weight and dimensions of the form traveller and the temporary and permanent acting loads. Steel is widely used around the world for the construction of bridges from the very large to the very small. A wide range of construction methods and sequences are available for steel bridges.

In addition, a parametric study was performed to evaluate the effects of the prestressing sequence, bottom slab thickness, and position of the prestressing anchors. ADAPT-ABI is Bridge Design Software with Construction Sequencing and Time-Dependency.
