Numerical Modeling of an Existing RC Frame for the Design of Strengthening through Composite Materials

Abstract:

In recent years, different strengthening techniques adopting composite materials have been proposed. Among these, FRP strengthening technique, which adopts Fiber-Reinforced Polymers strips, has become quite popular for the rehabilitation and seismic improvement of existing buildings. In this paper, this composite material is adopted to design the strengthening of an existing Reinforced Concrete (RC) frame. Firstly, its behavior is considered up to failure condition by performing a Finite Element (FE) analysis that incorporates a non-linear constitutive relation for the material named 2D-PARC. Then, based on the obtained FE analysis results, a strengthening design of the frame by adopting composite materials is developed and discussed.
