Análise de treliças em galpões metálicos com uso de software comercial

Abstract

In view of the different types of materials and construction methods used in civil construction, the present work focused on the use of steel. Metal structures have been showing great growth as economical and versatile solutions, mainly linked to their use in warehouses, whether for commercial, industrial or goods storage purposes. To choose the most advantageous structural model for the building, it is necessary to analyze the cost, the capacity of the building to resist efforts and its behavior in the face of external demands. To this end, it sought to verify and compare the performance of a metallic shed with Pratt's scissor truss with another formed with Pratt's arch truss. Both warehouses will have the same geometric configurations regarding their dimensions, free span and structural components, only differing in the geometry of their roofs. The dimensioning for the two alternatives will be made using the CYPE 3D software, which will provide us with the behavior of the structures before the requesting actions, through the calculation memorial and displacement and stability images. Normative indications of ABNT NBR 6123, ABNT NBR 8800 and ABNT NBR 14762 will also be followed. Having verified how each structure behaves in the face of external requests, we will start to check which typology has the best cost-benefit ratio. With the quantity of material generated by CYPE 3D and the budget of the warehouses realized through the adoption of the average price of each structural component in Goiânia.
