Análise linear de estruturas de concreto armado com redistribuição de esforços: estudo de caso

Abstract

This work is dedicated to a case study, where, from the architectural design of a five-story residential building, modeling, loading, processing, detailing and analysis of the results are developed, using software for dimensioning reinforced concrete structures, TQS, with subsequent presentation of the results obtained for the steel consumption of the beams belonging to the standard floor. Firstly, in the configuration in linear regime without redistribution of efforts (δ = 1.0) – reference design – and then in linear regime with redistribution of efforts for values of the redistribution coefficient δ = 0.95 and δ = 0.75. Observing the global stability parameter, γz, limited to 1.1, for the classification of structures as fixed nodes, a necessary criterion to enable the use of values for redistribution of efforts lower than δ = 0.90. And still with the attendance of the relation x/d limit for each situation. Keywords: Linear analysis, redistribution of efforts, reinforced concrete, TQS.
