to [1], inside of these buildings creates vibrant urban settings where residential, commercial, and recreational zones are found together. The complex process of the choice to construct high rise is made in order to combat the ills of urbanization while creating visibly desirable, functionally feasible, and economically viable urban environments.
G+19 RC frame construction with the Non Linear Static Method used. Pushover analysis is a known seismic performance method which helps shed light on how structures respond to lateral stresses. Finally, at fracture, each component is fatigued. In order to assess the safety and performance of the G+19 RC frame construction which is a typical high rise building, it is necessary to examine its reaction to seismic forces. Also, in the initial research, a detailed description of the loading condition, structural configuration, and material properties are presented. The importance of model these non linear material and connection behavior correctly is highlighted. Pushover analysis, otherwise called Non-Linear Static Method, is what engineers use to test how buildings can resist earthquakes by gradually succeeding ones. It will be defined by Indian Standard Code 1893 part1:2016, the RC frame structure will be defined using Indian Standard Code 456:2000 and different sections of code IS 875 will be used to determine the seismic load. Key Words: Frame Structure, ETABS, Pushover, Nonlinear, G+19 structure, Response Spectrum Method.
1. INTRODUCTION There are many reasons that tall buildings are built, depending on economic, geographi and sociological conditions. When there is a lack of available land in a highly crowded metropolitan area, it is more efficient to build tall structures as vertical construction means that space is utilized in an effective manner. It also helps in vertical development for addressing the rising demand for housing and commercial spaces in congested urban areas where land utilization has to be optimized to the core. In addition, tall buildings symbolize financial success and serve as notable symbols to attract the attention of the town and augment its reputation and its international recognition [1]. Also economic reasons come into play in the development of tall structures as developers are trying to find less cost effective solutions in places where land price are very expensive. However, it is also found that some of the high rise buildings have incorporated the sustainability and energy efficiency elements in the buildings. Also, the mix of this kind of projects, according

Figure 01: Tall RC Frame Structure. [4] Earthquakes are any earthquakes that there exist which causes seismic activity that does have a large impact on buildings, the ground shaking are seen both in the vertical and horizontal orientations. The seismic waves, that originate from the epicenter of an earthquake, would cause vibrations which may endanger structures. The effect of the two is dependent on its distance from the epicenter, soil composition as well as specific architectural design. Structural damage occurs; fissures arise in walls and foundations, or partial or whole collapse of the structure may occur due to seismic activity. The inherent frequency of a building coinciding with some of the seismic wave (or earthquake) frequencies such that a resonant condition occurs in which the shaking increases. Under particular situations it may compromise the stability of foundations by soil liquefaction. A weakened infrastructure is further stressed by aftershocks. Second,
