EARTHQUAKE RESISTANT COLD-FORMED STEEL BEAMS WITH FLY ASH CONCRETE ENCASED TRAPEZOIDAL CORRUGATED WEB

摘要

ABSTRACT The present invention describes about the cold-formed steel beam with corrugated webs which enormously increase their load carrying capacity as well as stability against buckling. More particularly, it explains the cold-formed steel beam with fly ash concrete encased trapezoidally corrugated webs with a view to enhance the strength and ductility. The beam with fly ash concrete encased trapezoidally web not only increases the moment carrying capacity but also the ductility. The super elasto-piastic property of encased corrugated web beams enhances the usage of it in the earthquake resistant structures and become a very economical design.
