Structural Optimisation and Cost Effective Light Weight Composite Cold Form Steel Structures

Abstract

Build up box sections are becoming increasingly popular in cold formed construction. This paper aims to develop the optimized innovative less weight composite column to replace the conventional hot rolled steel columns in aspect of weight reduction and economic design for steel and composite building to achieve this less weight concept. Column are made using cold form channel section used in the form of multi sectional alignment which is limbed with high strength bolt and ultra-lightweight concrete filled inside the CFS section to increase the stiffness and strength. This study deals with the parametric optimization of the concrete filling aspect ratio to avoid the buckling and various CFS section alignment to resist more load. The complete investigation of this research is carried on ANSYS and non- linear compressive load testing is done and results are compared with conventional type in considering the economic design.
