Abstract: A differential equation for the slip effect of a continuous superposition beam under asymmetric loads and flexible support was formulated in this study to study the effects of the stress distribution law and the slip effect of laminated frame under actual loads on the overall stress level of the frame. While considering continuity and free boundary conditions, a semi-analytical solution to the slippage of the superposed beam interface was proposed. An experiment for frame strength was designed based on the results of the numerical analysis. A field stress test was performed on the main frame and sub-frame, and the results demonstrated that slip effect could influence the overall mechanical properties of the laminated frame to some extent. Considering slip effect conforms to the actual mechanical properties of the laminated frame.
