Método para o dimensionamento e otimização de tesouras de cantoneiras duplas para galpões de vão único

Abstract

In order to obtain simple, safe, economical steel scissors and with the optimization of these three criteria, the work in question shows a simple steel shear with double-edged profile bars of equal flanges, following the criteria of standards NBR 6120, NBR 6123 and NBR 8800 for the dimensioning. In view of the results of this study, a method for the design of bars of metallic structure, a relation with the first amount of the scissors and te distribution of the loads, weight and cost of the structure for the presented construction are found.
