CONNECTING-SECTION STRUCTURE OF CORRUGATED STEEL PLATE AND CONCRETE FLOOR SLAB IN CORRUGATED STEEL-PLATE WEB PC BRIDGE

摘要

PROBLEM TO BE SOLVED: To ensure the integrality of a corrugated steel plate and upper and lower concrete floor slabs, and to increase resistance against bending moment in the direction orthogonal to the bridge-axis working to the connecting sections of the corrugated steel plate and the concrete floor slabs in a PC bridge using the corrugated steel plate for a web. SOLUTION: Web plates 5 and 5 in which through-holes 5a are formed at intervals in the bridge axial direction are arranged in rows in the direction orthogonal to the bridge-axis, on the concrete sides of flanges plates 4 welded on end faces on the concrete floor slab 1, 2 sides of the corrugated steel plates 3, and unified with the flange plates 4. Reinforcements 7 are inserted into the through-holes 5a of the web plates 5.
