摘要
A system for construction of double U and single U steel composite structure for bridges and methods thereof are disclosed. The system comprising: a base slab (1), a plurality of top and bottom U shaped beams (2, 8) made of I section, exterior top and bottom slabs (3, 9), a bottom deck slab (4), foot path (5) and kerb (6). In precast scheme U shaped bottom beams (2) are placed at about 2m interval and exterior slab and bottom deck slab are casted. Top U beams are casted in inverted position. Base slab is provided and bottom U system is placed and top U system is provided over bottom U system forming a full frame vierendeel type composite as a self-straining unit. Earth filling compaction to be done. The approaches are made of single U section and being extended with I beam and RCC slab. Cast in situ scheme is done similar.
