Estimation of the Maximum Von Mises Stress in the Steel Truss Bridge Gusset Plate Connections

摘要

Methods for approximating normal and shear stress distributions at the critical sections of gusset platesare presented in this paper. The critical sections considered include the horizontal section between thechord and the diagonals and hanger, the vertical section on the both sides of the hanger, and thechord splice. Once the stress components are known at the critical sections, the equivalent stress,known as Von Mises stress, can be estimated to identify potential high stress locations and determinedthe maximum stress on the gusset plate.
