ESTUDO DE CASO: ANÁLISE ESTRUTURAL DA COBERTURA METÁLICA DE UMA OFICINA SITUADA EM RIO VERDE - GO

Abstract

The non-mandatory structural project to obtain the construction permit in the city of Rio Verde has contributed to the increase in the number of warehouses built without structural planning and specialized monitoring. In this context, the objective of this study was to analyze the metallic cover of a workshop built without a structural project and to verify if it is able to resist the standardized requests. The work lacks a brace system, French hand and chain. The survey of the structure, the loads and the analysis of the shed were made using the software Cype3D. The results indicated problems on Tuesdays, banzos, amounts and diagonals, in addition to displacements above the recommended. A model structure was created by correcting the profiles with problems and adding the missing elements, without changing their constructive form. Five ways of installing the horizontal brace in X were also compared, on the third plane. When comparing the corrected structure with the original work, there was a large increase in steel consumption, possibly due to construction errors. The five brace types compared did not show significant differences, however the use of this element drastically reduced the longitudinal detachment. In addition, the amount of steel used to add the missing components was very small. Therefore, the research revealed the importance of structural design and the influence of unused elements.
