Masonry infill walls are usually used as partition walls and external walls to fill the space left by the RC building structure. The effect of an infilled wall is often ignored in the normal practice of designing RC building frames, which can lead to unsafe and expensive designs. Infill walls alter the behavior of RC frame structures by making them stiffer under lateral load. Therefore, the effect of infill masonry wall should be taken into account for safe design. Due to the limited availability of building space in desirable sites in metropolitan cities, architects have been forced to design structures with asymmetrical shapes in the modern age. Re-entrant building designs effectively used f irregular or limited plots to enhance space usage in densely populated locations. The redistribution of forces and displacements within the structure is caused by the considering the infill wall. Increase in the stiffness due to infill wall results in increased in base shear and story shear significantly as well as natural time period, story displacement and story drift is decreases across all the model. Hence for safe design, the effect of infill wall in must be considered in seismic analysis
