Seismic Analysis and Retrofitting of Existing R.C.C Building

  Susrasthi Sankhwal,  Nirav Patel

Seismic Analysis is a part of structural analysis and it deals with the calculation of the response of a building structure to earthquakes. Retrofitting of an existing building is often considered to be more cost-effective than constructing a new building. It represents an opportunity to upgrade the overall performance, sustainability and efficiency of an existing building. Seismic retrofitting is mainly done to provide existing structures with more resistance to seismic activity due to earthquake. Most losses of lives in the earthquakes in developing countries have occurred due to collapse of buildings that are mostly non-engineered. However, not designed and constructed to meet the seismic requirements. In this study, the seismic analysis of reinforced concrete (RC) buildings with different types of bracing (Diagonal, V type, and inverted V type, X type) is studied. The bracing is provided for peripheral columns. A six-storey (G+5) building is situated at seismic zone III. The building models are analyze by equivalent static analysis as per IS 1893:2002 using Staad Pro V8i software. The main parameters consider in this paper to compare the seismic analysis of buildings are lateral displacement, storey drift, axial force, base shear. It is found that the X type of steel bracing significantly contributes to the structural stiffness and reduces the maximum interstorey drift of R.C.C building than other bracing system.

Keywords- Keywords: seismic analysis, base shear, retrofit, bracing, storey drift, etc.
