- Abstract
- HR (Hot-Rolled steel coil) plates are produced by straightening hot-rolled steel coil with a primary objective to substitute conventional thick plates, thereby avoiding a number of difficulties encountered in the production and shipment of thick plates and relieving supply problems. In order to evaluate the applicability of HR plates to building structures under KBC 2009 steel design provision, a total of four full-scale welded built-up H-beam with simple supports are tested together with associated key material testing. The full-scale beam specimens are respectively classified into two categories; the flexure-dominated beam and the shear-dominated beam; to evaluate both the bending and shear strength separately. In the material test the HR plates satisfy both the tensile mechanical properties and the CVN toughness which are required in the current material specification. Both the flexure-dominated and the shear-dominated beams exhibit sufficient capacities that exceed the nominal strengths specified in the KBC 2009, thus confirming the applicability of the HR plate.
