The Fibre Reinforced Polymer (FRP) tubular composite column is a new form of column which helps in obtaining the higher structural performance. The composite column considered here is same like steel-concrete composite column, except that the outer steel section and the reinforcing steel bars are replaced with the hollow FRP section and FRP bars. The manual calculation for developing the interaction chart is difficult and time consuming. And, there have been no attempts made for developing P-M interaction charts for FRP composite columns. So, the purpose of the study is to develop the design of composite column by solving the equations of different points of interaction chart. In order to study the effect of various parameters on the P-M interaction chart, the parametric study is carried out. The parameters considered for this study are the percentage of reinforcements, gross sectional area and shape of the composite column. Finally the charts are developed considering different reinforcement percentage (varying from 1 % to 6 %) for square and circular column.
