Aspects of finite element modeling of strengthened RC walls with opening

Fiber-reinforced polymers are materials used to recover/strengthen reinforced concrete structures load capacity. This material exhibits good mechanical properties with low self-weight. work performed a series of nonlinear finite element analyses in one-way (OW) wall panels central cut-out opening, strengthened using carbon fiber-reinforced polymer (CFRP). The experimental tests conducted by Mohammed et al. (2013) were as benchmark. numerical simulations carried out the commercial code ATENA, which and geometrical nonlinearities accounted. As result, models reasonably predicted ultimate walls, all presented crack pattern similar tests, verifying that CFRP addition caused more distributed pattern. results obtained this revealed strengthening 24-50% enhancement load. Additional extend proposed new equation can be predict OW walls without strengthening.
