The linear elastic fracture analysis of stiffened plates with central through crack under uniform bending external loading are carried out; The method to calculate and analyze stress intensity factor of cracked stiffened plate is put forward; The thickness effects are considered in the analysis of stiffened plate and the stiffened plate structure is discretized into a plate with center through crack and stiffeners; The bending fracture problem of stiffened plate with center through crack under uniform bending external load is analyzed by using Kirchhoff classical plate theory, finally the lateral forces between each other are determined by the deflection coordination equilibrium equation at discrete locations. For specific structure parameters, the interaction relationship curve of the stress intensity factor vs. crack length for stiffened plate under uniform bending external loading is give.
