Abstract –
provide a comprehensive review of the existing methodology and procedure for the condition assessment and seismic evaluation of buildings with reinforced concrete frames into the software. The research focuses on the particular challenges and issues associated with these structures, including their age, size, complexity, and variations in the way they are planned, constructed, and maintained.
In this study, four G+3 reinforced concrete (R.C.C.) buildings' conditions are evaluated using the application of Rapid Visual Survey (RVS). A G+3 R.C.C., one of the examined buildings, was chosen for a comprehensive evaluation since it would also need to take into consideration a vertical extension that would add one or more stories. The present building's performance was assessed, and a simulation of the structure's response to seismic forces was conducted with the use ETABS, an advanced structural analysis and design program, to offer a thorough condition assessment of the seismic evaluation and performance and the structural integrity of an old structure. This study's main goals were to evaluate the building's existing state, detect problems with the structure, and create efficient retrofitting plans that would improve safety and conform to modern building requirements with respect to new IS building codes. Numerous important conclusions emerged from the investigation, including the possibility of seismic vulnerabilities, insufficient reinforcing, and overstressed columns. Customized retrofitting techniques such as column jacketing and the addition of shear walls are also designed and assigned in the software in accordance to IS 15988 : 2013
The goal of earthquake evaluation, on the other hand, is to ascertain how resilient a structure is to seismic forces. This assessment is essential in earthquake-prone locations to prevent structure collapses that might have disastrous effects. A range of methods are employed for doing seismic assessments, from manual computations to sophisticated software modeling tools like as ETABS. This research involves a case study of a real reinforced concrete framed building where the seismic assessment and condition analysis are conducted in accordance with new IS guidelines. The research includes a complete history of the building's design, construction, and upkeep as well as a summary of all the nondestructive tests that were performed on the structure. After the study's results are analyzed, recommendations are given to improve the building's seismic performance and safety by determining the location of any structural member problems. Earthquake evaluation and condition assessment work together to provide essential data that can extend a building's lifespan, improve its functioning, and increase safety. The current study aims to investigate the importance, methodologies, and outcomes of existing structure seismic evaluation and condition assessment, highlighting their respective roles in the larger picture of operation and preservation.

However, as these structures age, they become more susceptible to deterioration and harm from various earthquakes as well as other man-made and natural pressures. This poses a significant danger to the general safety of the town, the safety of its citizens, and the financial and social costs. Building owners, property managers, and the general public have serious concerns about preserving the integrity, safety, and long-term worth of structures. Seismic evaluation and building condition assessment are two essential parts of this work.
Assessing building structures and their ability to withstand seismic events has been an important area of research for many years. One of the most important topics has received a great deal of attention from many researchers but mostly the researches are done using some old programs and software such as Sap2000 and generally most of them are not conducted as per Indian standards. Therefore a thorough study is required as per Indian standards and with accordance to IS 15988 : 2013 to show proper retrofitting of the improper structural elements Some of the following researches had provides an in-depth assessment of the studies and research efforts that have
