    • Abstract
  • In this paper, the theory. of flexure and torsion for the truss beam bridge is adopted to drive differential equations of the elastic lateral stability for the truss beam bridge with a trapezoid section. The lateral stability of a simply supported truss beam bridge is analyzed by using the Galerkin's method. Finally the critical load qcr for its lateral instability is obtained.
