Análise estrutural do conjunto de palhetas de um aerador da estação de tratamento de efluentes

This work aims to find the maximum tension in a group of blades in a Sewage Treatment Stations in a company located in Vale do Paraíba. First, the calculations of the strength requested by the effluents on the structure are done, and the optimum torque of the frame screws is researched. From these data, static simulations using appropriate software and the finite elements method are performed. Based on the results, a possible solution to reduce the strength in this structure is proposed. This study will be provided as a consultation material to the company

Projeto estrutural de galpão metálico segundo recomendações da NBR8800

This work deals in a general way, the history and advantages of steel buildings, as well as its increasing usage in Brazil in the last century. This work also generally describes some types and its uses of metal frame. It also demonstrates the use of the NBR 8800: 2008 standard and its calculation methods through the scale out materials regulated in Brazil for an industrial warehouse project small and simple portico metal frame. Given that the construction requirements include a locational influence following the normative indications of the NBR 6123, for the winding scale out, since this effect combined with the permanent loads must be seriously evaluated due to the shape type effort about acting simultaneous axial force and bending moments obeying the limitations applied to the structure according to NBR 8800. As it has been explained the calculations that ensures mechanical stability and suggesting an analysis of the efficiency of the used materials
