International Journal for Research in Applied Science & Engineering Technology (IJRASET) ISSN: 2321-9653; IC Value: 45.98; SJ Impact Factor: 7.429 Volume 9 Issue XI Nov 2021- Available at www.ijraset.com III. METHODOLOGY AND MODELLING Modeling and analysis of this research is done in CSi ETABS software. For complex structural analysis, a software like CSi ETABS helps in visualization of the structural model and also deprive the tedious calculation of the analysis results in complex structures like the structures under consideration in this study. The table 1 is explained the model cases used on in this project.
