Abstract:

A new technique to improve the ductility of steel cantilever is presented in this research. Glass fiber reinforced polymer (GFRP) plates bonded to the upper and lower steel cantilever flanges. The cantilever simulates the beam-column joint beam part of the moment-resisting frame subjected to later load. Two validation are conducted to assess the numerical modeling. First, we validate steel cantilever experimentally subjected to symmetric cyclic loading to verify this type of loading. Second, supported steel beam strengthened with GFRP experimentally subjected to monotonic loading to verify GFRP element and the bond between steel and GRFP. Three-dimensional modeling was developed using ANSYS software for steel cantilever without GFRP to study their behavior under cyclic loading. This investigation revealed a significant increase in the strengthened cantilevers' ultimate capacity and ductility with no sign of failure in the bonding adhesive up to GFRP failure.
