the building is examined under the lateral force vector, which provides the design forces and earthquake design moments. These forces and moments are combined with forces and moments due to dead and live loads according to load combinations to give design forces and moments in structural members. A frame building's performance during a seismic attack would be improved if it could be guaranteed that plastic hinges only occur in beams and not in columns (Beam mechanism) and that member shear strength is greater than the shear strength corresponding to flexural strength. This can be seen as the actual beginning of performance-based seismic design, where the process of design controls the building's overall performance. Iteratively, performance-based seismic design synthesis starts with selecting a performance objective, then develops a preliminary design, evaluates whether the design satisfies the performance objective, and, if necessary, redesigns and reassesses the design until the desired performance level is reached. As a result, before being constructed, such structures need to be properly analyzed and designed. Every year, an earthquake of about magnitude 3 strikes, leaving thousands of people dead or injured, thousands homeless, and reinforced concrete buildings severely damaged due to irregularities in the structure's mass and design and contradictory seismic responses. Different earthquakes occur in different places and have various intensities and magnitudes, as well as varying levels of destruction. As a result, it is important to investigate the seismic behaviour of RC structures for a variety of responses, including base shear and storey displacement. Calculating the building's seismic response requires seismic analysis, which is a step in the structural design process in areas where earthquakes are common.
understand performance-based seismic design methodology. We can more effectively design new structures and more realistically evaluate existing structures assess to the performance-based seismic design approach. Performancebased seismic design carefully assesses how a structure is likely to function under a possible earthquake threat. Identification and evaluation of a structure's performance capacity are crucial steps in performance-based design, helping to guide the many options that must be made. In this paper, a brief review is based on a multi-story RCC building with non-linear analysis and performance-based seismic design. In this project work, an attempt is made to fully understand the method and process used in the performancebased design and its implications for producing an earthquake-resistant design.

Words: Performance-based seismic design, Performance objective, Non-linear static analysis, Capacity, Demand. 1. INTRODUCTION Modern seismic design codes allow engineers to compute design forces and design displacements using either linear or nonlinear analyses. Contains four methods of analysis: linear static analysis, linear dynamic analysis, nonlinear pushover analysis and nonlinear time-history analysis. These methods deal with the design and analysis of framed constructions, primarily buildings, and bridges. For design engineers to fully apply the two nonlinear methods, advanced models and nonlinear procedures are required. In the recent past, the impact of urbanization is very common. In today’s generation, the building and development of skyscrapers are much needed, but when an earthquake occurs those structures can be damaged to a very large extent. Earthquake-resistant design of building in India is carried out as per guidelines given in code IS1893:2002. According to this guideline base shear is computed based on perceived maximum seismic risk characterized by a maximum considered an earthquake, the importance of building and reduction in demand depending on perceived seismic damage of the structure. The computed base shear force is then distributed to floor levels which depend on the amount of mass present at the storey level and its height. After that,

2. LITERATURE REVIEW P.S. Mehare, M. Joshi [1] studied how well buildings perform during earthquakes using performance-based seismic design. In the current study, various sets of reinforcement are made at various levels to study how well buildings perform under the influence of an earthquake. Ultimately, the best possible combination of reinforcement is given, one that is cost-effective and whose damage is minimized to achieve the desired immediate occupancy level. The second is to determine the building's performance
