Projeto da viga principal de uma ponte rolante: uma abordagem analítica e computacional

Abstract

Overhead cranes are used to transport and lifting loads with high capacities and high working cycles. It is a structure, usually installed inside buildings, being able to move loads, materials, and equipment in the longitudinal, transverse and vertical directions. In this sense, the porposed work is the design of a single main bridge girder with load capacity of 15 tons. The structural calculation procedure is based on ABNT NBR 8400: 1984 and ABNT NBR 8800: 2008. ABNT NBR 8400: 1984 establishes the minimum criteria for the design of equipments for transportation and lifting, while ABNT NBR 8800: 2008 defines the minimum requirements for the design of steel structures. After the design of the girder and selection of beam size, a stress analysis is performed using the finite element method using SolidWorks software. In this analysis, it was verified that the stress level and structural deflection are in compliance with ABNT NBR 8400:1984 and ABNT NBR 8800:2008.
