Estandarización de diseño de estructuras de acero para soportar grúas viajeras

Abstract

An overhead crane is mechanism that aims to move loads along the structure that supports it. Its design is regulated by various international codes, so it is necessary to decide which one should be use in a design in our country. Two the most important international design codes will be studied in this paper. The first one is published by CMAA (Crane Manufactures American Association) and the second is referred to be used by AISC (American Institute of the Steel Construction) as published by AISE (Association for Iron and Steel Technology). The main objective of this paper is to create a Microsoft Excel based tool that integrates all the concepts necessary to design the support structure (runway beam, brackets and the connections between them), that would allow creating designs using the crane´s technical specifications only. Additionally a constructions requirement guide is included, which contains the design procedures for steel elements, such as blending stresses , shear, axial compression, axial tension, biaxial bending, compression and flexion the design of brackets and connections.
