There are primarily two distinct kinds of irregularities present inside the building; the first of these is known as plan irregularity, and the second is known as vertical irregularity. Because irregular structures operate differently than regular structures, the introduction of irregularity into a structure results in difficult design and construction challenges. These issues are caused by the difference in behavior between the two types of structures. The reaction of such a building under seismic stress is dependent on a number of different parameters, and it is of the utmost importance to understand the behavior of such an irregular structure in order to establish a new method of design and construction through which the performance of the same shall be assessed. Because of this, the current research was carried out in order to get an understanding of the behavior of irregular structures that have bracing systems. In order to do this, three distinct kinds of irregularities were selected for the 12-story building: an H-shape, an L-shape, and an O-shape. In light of the findings of this research, the use of a V-bracing configuration is of particular importance. Heavy stuff was loaded onto the sixth floor and the ninth floor, but not at the same time. It was decided to do the dynamic seismic study in seismic zone V at Staad, and the analysis was carried out there.Professional software. Finding out how effective the bracing was, in addition to doing an analysis of the irregular structure, was the primary focus of this particular research endeavor, which led to its successful completion.
