Expansion joints are often required between adjacent buildings and are often introduced to separate two or more parts of the same building. This dissertation reviews the design, selection, testing and recent developments in expansion joint and expansion joint performance from first principles (assumptions). A comparison was made with current standards and codes of practice. Joint locations, their specifications, and other significant architectural and fire issues with respect to expansion joints were also discussed. Expansion joints affect the execution of works, construction sequence and facade design and also act as a source of monsoon leaks throughout the life of the building. To avoid all these complications, architects nowadays prefer buildings without expansion joints. A limit of 45 m length of structure has been prescribed by IS 456 (plain and reinforced concrete code) for RCC structures to be followed. Otherwise, it is necessary to design structural elements for additional stresses due to temperature changes. This case study deals with a G+5 residential building with an approximate covered area of 2700 m2 with 6 expansion joints, dividing the building into six different towers. The main objective of this dissertation is to study the response of the tower acting individually as in the case of expansion joints and the response of the tower when acting as a whole (without expansion joints). The main monitored parameters are floor displacement, maximum floor displacement and time period. Six models were created and time history analysis was used to analyze these models. The parameters of each individual tower and the tower as a whole were analyzed using time history analysis using data from past earthquakes. Time history analysis was performed using ETABS2013 software.
