The main objective of this work is to develop innovative models of tubular connections in order to decrease the trusses total manufacturing cost and assembly time, making its use more economically viable. The truss joints were verified according to international codes and publications, and a commercial software of structural analysis was used to verify the truss bars resistance. The innovative tubular connections proposed are joints between the diagonal and chord using a single bolt and a plate, and one internal tube with bolts to link the chord bars. To analyze the truss global behavior and the developed connections, real scale experimental analyses of circular hollow section multi-planar trusses were carried out, with 30.0 meters of span, and 2.0 meters of height. The final results demonstrate the proposed connections efficiency and the truss good behavior, with low weight and manufacturing cost, besides a quick assembly. © (2010) by COPPE - Federal University of Rio de Janeiro All rights reserved.2 11771184Requena, J.A.V., Vieira, R.C., Junior, N.O.P., CHS Multi-planar Trusses Analyses-Theoretical and Experimental Analyses for Use as Purlins (2008) Proc. of EUROSTEEL 2008 5th European Conference on Steel and Composite Structures, pp. 1767-1772. , R.
