Abstract

The development and innovation of Science, specifically in the branch of construction in Civil engineering, has led the implementation of new alternatives in analysis, design and construction of industrial buildings. For this reason, in this research it was proposed to carry out a study of structural behavior of two types of self-supporting roofs: flat and circular, which were analyzed using computational tools for simulation through finite elements, in which initially the structure made up of columns, beams and steel sheets was completely modeled with an equivalent cross section, which made up the self-supporting roofs; then only the steel sheets with real cross section were discretized, and it was noted that in the extremes were the greatest stresses generated by the application of horizontal and vertical loads; and the maximum displacement of the circular roof was 14.32 % of the flat one.
