Buckling Analysis and Mode Shapes of Composite Columns with Self Compacting Concrete Infill (SCC) using MIDAS CIVIL

This Research focuses on validation of Ultimate axial load carrying capacity of CFST column filled with self-compacting concrete using MIDAS CIVIL finite element software. Three-dimensional nonlinear finite element model is developed to study the force transfer effect between concrete and hollow steel tube. Model is developed for understanding the complex behavior of conventional composite circular steel tube and self-compacting concrete infilled tube with various grades and different diameters (D), thickness (t) and length (l). Diameter of column varying from 337mm to 483mm and length from 200mm to 680mm is considered as experimental results are available from different national and international research works including R& D works carried out at Civil Engineering research laboratory at Ghousia College of Engineering by previous UG, PG and research scholars since 2010 till date.
