The paper discusses tensile load carrying capacity of an open lattice structure IsoTruss through finite element
modeling and analysis. IsoTruss is Web like structure consisting of isosceles triangle within the geometry of its
structure. IsoTruss provides a light weight structure when carbon fiber is used as the working material. The tensile
strength of IsoTruss for two set of position of longitudinal members with respect to bay length is studied. The study
concludes that IsoTruss with internal and external longitudinal members carry more tensile load compared to the
IsoTruss with only internal longitudinal member. Also the Strength to Weight ratio for IsoTruss with internal and
external longitudinal is higher than IsoTruss with only internal longitudinal members.
