【 摘 要 】

The research carries pseudo-static test on 6m-span spatial arch truss specimen with three centers under vertical circle loading, and analysis on their failure process. The hysteretic loops, skeleton curves and stiffness deterioration is obtained. The experimental results showed that the failure of arch truss specimens starts buckling and cracking of lower chord, then the members gradually formed local cracking in this region, and finally the midspan with the greatest force cracking leads for the truss to form geometrical mechanism and collapse; When the structure fails, many members enter the plastic stage. The overall plastic deformation is large and the energy consumption performance is good.
