Numerical And Experimental Analysis Of Tubular Plane Trusses For Use In A Standardized Roof System With Long Span [análise Numérica-experimental De Treliças Tubulares Planas Para Coberturas Padronizadas Para Grandes Vãos]

摘要

The purpose of this study is the comparison between experimental and numerical data of a roof system made of tubular steel sections. Such roof system is applied mainly for supermarkets, large stores and industries. To evaluate the structural behavior of this system, a 900m2 prototype was built, - an unprecedented opportunity in Brazil to accomplish experimental tests with usual loads for this type of structure. Evaluating the behavior of the entire structure, with all the results obtained on experimental tests and numerical analysis, it was concluded that the prototype is in general accordance with the designed model in terms of stresses and displacement.
