8. Conclusion When this project started 4 to 5 years back, it was very challenging. Firstly, it was thought that at the top where transfer girder was happening, expansion joint will be provided. This way transfer girder would have been sliding at the top of one wing and fixed with other wing. But with this approach, it was difficult to control the building deflections at the top. The behavior of whole building was getting uncertain. So, the approach that has been explained in this case study was adopted. This theory and the striking symmetry in the building helped a lot in achieving an apt The Bridge and Structural Engineer
and consistent behavior in the building. But to achieve this lot of research and hard work was done. The building was analyzed in ETABS and STAAD Pro. The grillage of the building to study the independent behaviors of various elements was also formed. Various manual calculations were done. This whole task in itself was quite interesting and thrilling at the same time. In the end, the hard work paid very well. The building design turned out to be quite satisfactory and as per everyone’s expectations. The construction of the building was completed in the year 2013. Today it’s one of the finest places in Gurgaon to live in. Volume 44
