|Abstract:||In the current paper, continuous damage mechanics is adopted to predict the fracture failure in the circular hollow section (CHS) joints, with the chord member reinforced using ultra-high strength grout. Isotropic damage is assumed and a single scalar damage variable has been adopted to describe the evolution of damage in the steel materials. The parameters for damage initiation and fracture are verified by coupon test. FE models combining material damage effects are analyzed for grouted X joints under brace in-plane bending. The geometric parameters of these models are based on previous tests conducted in National University of Singapore (NUS). The numerical results show very close agreement with the experimental data. Further analyses regarding the effect of damage initiation strain, fracture strain, loading rate are also carried out.
