ASYMMETRIC COMPOSITE BEAM WITH CORRUGATED WEB

摘要

PURPOSE: An asymmetry composite beam having a wave web is provided to control the position and the number of bent points of a steel beam according to load and drooping and to reduce the height of the structure. CONSTITUTION: An asymmetry composite beam having a wave web is composed of a steel beam, a deck plate, and a concrete. The steel beam is composed of an upper flange(10), a lower flange, and a web(30). The web connects the upper and lower flanges. The deck plate is put on the lower flange. The concrete is poured on the deck plate. The width of the lower flange is more than the width of the upper flange. The lower flange is composed of an upward bent unit(22) and a horizontal bent unit(24). The web has a waveform protrusion(32) which is bent toward the front and rear of the web along the longitudinal direction of the steel beam.
