BUCKLING STRENGTH AND POST-BUCKLING BEHAVIORS OF TUBULAR TRUSS TOWER

Experimental results on the behaviors of four tubular towers, two of plane and two of space trusses subjected to severe cyclic lateral loads are reported. The effect of the horizontal strut and that of the direction of load on buckling strength and post-buckling behavior are examined. Ultimate strength and force-deflection curves of each specimen are compared with the analytical solutions by the rigid-plastic method.
