| Abstract: | Ladder finite strip stiffness matrix is derived to Solve the bending problems ofsome irregular plates at various boundary conditions.This method can be applied to thehexagonal plates and upper or lower bottom simply supported trapezoidal plates to solvebending deflection occurring in general chemical equipment.Compared with the accurate so-lution,the errors of two examples are 0.055 and 0.042 respectively. The accuracy is enoughfor enginerring practice. This method can also be applied to the irregular plates possessing asymmetrical axis with satisfactory accuracy. |
