Summary For seismic analysis of unreinforced masonry (URM) buildings characterized by a box‐like behavior, a widely accepted model is based on the equivalent frame idealization of walls. The equivalent frame model uses 1D elements to represent the vertical piers and horizontal spandrels which are connected by rigid nodes. The mechanical characterization of the elements is one of the crucial aspects to predict reasonably the building seismic behavior. Through the comparison with pseudo‐static and dynamic experimental tests performed on two‐story full‐scale buildings, this paper validates the frame modeling in the OpenSees framework, which includes a fiber‐section force‐based beam element for the axial‐flexural behavior, coupled with a cyclic shear‐deformation phenomenological law.
