| Abstract: |
The paper presents one innovative idea for strengthening of steel truss nodes by UHPFRC. The nodes are totally encased in the UHPFRC with no additional conventional reinforcement. The connection between steel and UHPFRC is realized by epoxy resin only without any shear connectors. For proving the efficiency of this strengthening method five specimens are going to be tested in laboratory: one reference bare steel node, and four encased. The parameters that are going to be varied during the tests are the concrete cover and encasement length of the elements entering the node. The very promising results from the preliminary FEM of the nodes are presented herein as well as the description of the experiments envisaged. |
