A nonlinear finite element study was conducted for the Y-12 Plant to evaluate the in-plane behavior of masonry infilled steel frames. ABAQUS was used to develop the finite element model and perform a parametric analysis. The model was verified by comparing the results with the experimental program series carried out at the University of Brunswick, Canada. The initial stiffness could be matched using an elastic model with an interface element. The ultimate load could be matched using the ABAQUS nonlinear concrete model for the infill. A softened interface was used to account for the localized mortar crushing that tends to occur at the corners of infilled frames. This model was used to match the secant stiffness at approximately 50% of the ultimate load. A parametric study was performed on the initial stiffness. Results indicated that an appropriate equivalent strut could closely match the behavior.
