The present paper illustrates a light weight composite IsoTruss structure and its characteristics in buckling through finite element modelling and simulations. IsoTruss provides excellent opportunities to enhance the strength to weight ratio of a structural element. The paper presents the comparative study of compressive buckling load carrying capacity with respect to bay length of IsoTruss under placement of longitudinal members at different location along the axis of IsoTruss. The study concludes that the IsoTruss exhibits global as well as local buckling characteristics for progressive bay length of IsoTruss. The IsoTruss with longitudinal members placed away from axis has better compressive buckling load carrying ability than the IsoTruss with longitudinal members nearer to the axis of the IsoTruss
