STEEL BOX GIRDER BRIDGE

摘要

PURPOSE: A steel box girder bridge is provided to make a design simpler and to improve economical efficiency. CONSTITUTION: The steel box girder bridge(20) contains a slab(21) forming an upper plate, a steel box(22) coupled with the slab(21) to form a main girder, and a pier(23) supporting the steel box(22). Wherein concrete(24) is compounded to the inner lower part of the steel box(22) locating in a negative moment section(L) formed near to the spot where the steel box(22) meets the pier(23), and the width of the concrete(24) corresponds to the width of the steel box(22), and the length of the concrete(24) is shorter than the negative moment section(L).
