ABSTRACT
To obtain the accurate analytical solution of internal force in portal frame being composed of non-uniform members subjected to the combination of vertical and horizontal loads, the force method was used to solve internal force of every key section of the non-uniform beam in portal frame with single-span. Gauss numerical integration method was used to simplify the complex integration when the deformation energy was calculated. The analytical solutions were verified by finite element method. Under the precondition of satisfied accuracy, the explicit expressions of bending moment, shear force and axial force of every key section of beam were obtained. The research work can be used as reference for the evaluation of portal frame members and for the programming of portal frame design codes.
