Resumen
In this work, an alternative capacitor bank framed structure was designed using glass fiber reinforced polymer (GFRP) pultruded bars. A finite element model was developed to simulate the structure static behavior and stability. Material properties were evaluated by a characterization test program. A prototype of the structure was built, instrumented and tested in order to validate the model. Additional three critical load cases were simulated. Results of these simulations showed large safety margins for static analysis. However, safety margins for global stability were marginal, indicating that the structure should be reinforced in some points. In general, results support the use of GFRP as an alternative material in the design of capacitor bank framed structures
