PEDESTRIAN BRIDGE WITH PERFORATED STEEL I-GIRDER

摘要

PURPOSE: A pedestrian overpass formed from girder with a hollow is provided to enhance cost effectiveness and structural efficiency since high bearing capacity is ensured with a small amount of steel materials. CONSTITUTION: A pedestrian overpass(2000) formed from girder with a hollow comprises columns(2200), I-sectional girders(110), a deck plate, slab concrete, a support(2100), and stairs(2300). The columns are installed on both sides of road at an interval. The I-sectional girders are horizontally placed in two rows to be supported by the columns. The deck plate is installed in order to be supported on the lower flange of the girders arranged in two rows. The slab concrete is located on the deck plate and supports a passage, through which pedestrians pass. The support is fixed to be protruded from the top of the slab concrete to the outside of the columns with a height enabling walk.
