A PARAMETRIC STUDY: TO INVESTIGATE NONLINEAR STRUCTURAL BEHAVIOUR OF CFS BUILT-UPBATTENED COLUMNS

Abstract

This study presents parametric study performed to investigate nonlinear structural behaviour of all the three categories (based on column slenderness) of CFS built-upbattened columns. The parametric study is conducted by varying the critical parameters viz, global column slenderness, different1geometries, plate slenderness (b/t ratio) and yield stress using the FE model validated. This extended study helps to apply the FEA results to verify the design strengths evaluated by DSM and EWM of AISI and European code specifications (EC3).
