Reliability Analysis of CFST Columns by Using Form and Latin Hypercube Method

Prakruthi, Khalid Nayaz Khan, Dr. N. S. Kumar

Abstract: Reliability oriented design techniques have been a powerful technique that is being globally adopting by structural engineers. The concrete filled steel tube column has many advantages compared to reinforced concrete member. This research aims to study the behavior of concrete filled steel tube (CFST) segments under monotonic loading by utilizing the finite element software ANSYS. Modeling accuracy is built up by using outcomes obtained from BS 5400, Eurocode 4 and AS 3600 codes. It is inferred that various parameters have considerable impact on the behavior of concrete filled steel columns, the prime variables are cross sectional area, thickness, and diameter of steel tube etc.., Most of the Researches on concrete filled steel tube is limited to deterministic approach yet in this thesis it also includes the reliability analysis of concrete filled steel tubes using First Order Reliability method and Latin Hypercube method utilizing 2R rel software.
