Abstract: In the lower-chord panel point of Shanxi Pinglu coal handling trestle pipe truss, outer ring plate and the vertical web rod H-Beam of the wind braced truss connect, its structure and the bearing?condition?are more complicated, which is beyond the scope of the relevant provisions of the existing national specification . In order to evaluate the static performance of such nodes, the full scale model static test is carried out, the elastic-plastic?finite?element?method is used to numerically simulate, and the stress development, deformation process and failure mode are analyzed during the loading process. The results show that the node has good carrying capacity and can meet the requirements of engineering design. The weak part of the node area is in joints between pressure pipe and outer ring, so we should strengthen measures.
