Stochastic optimization of hollow cfrp concrete filled columns

Columns have always been made of steel, timber or reinforced concrete which have been used in residential and industrial buildings. This study aims at obtaining effectiveness which can be attained when Carbon Fibre Reinforced Plastic (CFRP) is used as the structural sections of columns. CFRP hollow and concrete filled columns are loaded using Euler's buckling loading conditions. Finite Element Analysis modes were performed on various columns sections with end conditions using ABAQUS software. Results indicate that there were deformations on the column sections due to loading according to the restraint conditions at the column ends. This failure condition in CFRP is similar to that of steel hollow concrete filled columns. Thus it is suggested that CFRP pultruded sections can be safely adopted as a substitute for steel columns in structure. The load carrying capacity of these columns is about 75% of their steel hollow filled counterpart.
