Experimental and Numerical Investigation of Space-Trusses with the Reinforcement of Stamped Connections
Three-dimensional structures made of steel bars, widely known as space trusses, are very frequently used at the construction of roofs. These structures consist of steel bars, connected by bolts at nodes. In Brazil, the connection usually employed in these 3D trusses is the so-called typical node, which is produced by stamping the ends of the bars, thus generating a low cost connection. Several accidents in space structures using this type of connection have also been reported in Brazil. This research proposed the use of constructive correction in the connection in order to increase its capacity. This work, based on computer simulations and experimental lab tests, small changes on the staking end-flattened connections such as reinforcement and eccentricity correction are evaluated. The results show an increase of 56% for collapse in the truss load carrying capacity when the suggested changes proposed in this article are used for the staking end-flattened.
