Upper and Lower Side Fixed Pre-stress(ULPS) Steel Beam and Simple/ Continuous Bridge Using ULPS

摘要

The subject innovation relates to a structural member of the building and civil engineering structures, the steel H-beam or I-beam or applying a high-strength steel for upper and lower portions on the steel beam with a built eopbim proposed beam upper and lower fixed prestressing steel material so as to enable the information field of hyeonggo span to have a purpose.; In buildings and civil engineering structures, which is installed the steel beams supporting the slab in the present design for this purpose, jidoe made that the steel viewing elastic re ganghyeongjae and the ganghyeong member upper and lower part of each high-strength steel material are joined ganggyeol, the ganghyeong member upper in a state of compression stress to act, and the tensile stress at the bottom of which a tensile stress caused by it, the ganghyeong a compressive stress is introduced in the upper material ganghyeong material at the bottom by being ganggyeol bonded to a high strength steel and bolted or welded on the top and bottom fixing the upper and lower beams prestressed steels, characterized in that formed prestress is introduced are proposed.
