Cyclic Behavior Modeling of Rectangular RC Bridge Piers Using Opensees

Abstract eng:
Considering various constraints in experimental program tests such as, limitations in budget, time and lab facilities, applying numerical studies in performance evaluation of structures is inevitable. While, conducting numerical analysis without adequate proficiency in modeling and analysis in nonlinear behavior range, could be deceptive. Therefore, in this paper, finite element modeling of reinforced concrete bridge piers has been established in OpenSees and, the experimental results of a couple of cyclic tests has been reproduced and compared. Fiber Modeling methodology has been elaborated and applied in this research and, the paper focuses on numerical assumptions regarding to modeling, analysis and, convergence of numerical computations. In addition the sensitivity of the local and global results to the modeling and analysis assumptions has been discussed. The numerical results obtained in OpenSees have been compared with the experimental and numerical results of previous studies in SeismoStruct program. It can be concluded that via available measures and assumptions, fiber section method has a fair capability of simulating the cyclic behavior of high and medium height piers. .
