In “Recommendation for the design and fabrication of tubular truss structures in steel (Japan)” , asymmetrical KK joint is outside the scope. However, asymmetrical KK joint may be needed for architectural design. So, in this study, the influence of asymmetry of a joint to the strength is examined by using FE analysis. First, simulation analysis of past experimental result is conducted for validity of analysis method. Then, using this analysis method, the influence of asymmetry of a joint is examined, through comparison with symmetrical joints. Moreover, an evaluation method for asymmetrical KK joint is proposed.
