Simplified beam-column models typically are not able to capture this effect and usually are suitable only for members that exhibit a flexure-dominated response. Modeling approaches of increasing complexity for the simulation of reinforced concrete shear walls are compared in this work. More specifically, we compare the common fiber beam element, a simplified fiber beam element based on the Timoshenko theory that considers separately shear and bending deformations and a third Timoshenko beam element where a multidimensional concrete law is used. The various approaches are discussed and compared against experimental results. It is worth noting that experiments implemented for the comparison exhibit different failure modes, flexural as well as shear failure. The numerical study provides an insight to the efficiency of the above methods in terms of computing demand, accuracy and ease of implementation.
