Resumo:
The industrials buildings are one of the segments of construction in most common steel in Brazil. The features in construction are rapidity of execution, a smaller volume of material and slenderness of de elements. In this dissertation evaluates the performance and the need consideration of initial imperfections and second order effects in the usual trusses structures in the sheds. Through modeling a set of trusses frames is carried out a parametric study of various types and seeks to provide a practical solution of pre-design. It carried out a comparison between the methodologies of second-order analysis: The simplified method MAES of the ABNT NBR 8800:2008 and the advanced analysis made in Autodesk Robot Structural Analysis Professional program. The result showed consistency between the methodologies of and order analysis. From a comparative study of the analysis of 1st order and 2nd order analysis is concluded on the small influence of 2nd order effects in this type of trusses systems. Proves to little sensitivity to the incorporation of initial geometric imperfections. They obtain the graphs of estimated consumption of steel and maximum displacements. For different structural solutions observes the incidence of types of trusses in the structural performance of maximum displacement. It presents a simplified procedure for preliminary design through tables and abacuses produced for different trusses.
