- Abstract
- A smooth hysteretic model based on an equivalent strut approach is proposed for masonry infill panels to be used in non-linear analysis of building structures. The hysteretic model furnishes a versatile and robust simulation tool for representing masonry infill panels. The report presents the development of the proposed hysteretic model. The methodology for calibrating the hysteretic model parameters is described. The hysteretic model is incorporated in the structural analysis program, IDARC2D Ver 4.0, for quasi-static cyclic and dynamic analysis of masonry infilled frames. Simulations of experimental force-deformation behavior of prototype infill frame subassemblages are performed to validate the proposed model and presented herein. A lightly reinforced concrete frame structure is analyzed for strong ground motions to evaluate the influence of masonry infill panels on the response.
