| Abstract: | The computer program SAMTJ is revised for stress analysis of non-concurrent spatial tubular joints. Multiplanar DT non-concurrent tubular joints with different eccentricity in the vertical diametrical plane of chord were computed by the revised program SANCMTJ. Finally, the effect of eccentricity on the stress at the possible hot spots is discussed. |

| Keywords: | spatial non-concurrent joint stress concentration factor hot spot eccetitricity |
