DIMENSIONING COMPARATIVE FOR EXECUTION BETWEEN BOLTED CONNECTIONS THROUGH HIGH RESISTANCE BOLT AND WELDED CONNECTIONS WITH COATED ELECTRODE

Abstract

The steel industry offers a wide variety of options for using steel in construction, such as thin steel, sheet metal, screws, welding materials, bars, cables, cables among others, thus making it possible to build a metal structure . Thinking about the construction of the same, then we imagine as the unions of the parts of the structure. Taking this into consideration, the present work has as scope the design of an industrial shed structured in steel, with the purpose of demonstrating how the beams-abutments and beam-beams connections do not even present, when screwing with high resistance screws ASTM A325, and welded connections with coated electrode. The advantages and disadvantages of the two processes were explained for a better connection to the proposed case. A theoretical analysis of the two cases was carried out, followed by sizing and checking to obtain an indication of the type of A325 high strength screw support for a section labeled and size and type of weld for the crimped section.
