Reinforced concrete frame with prestressed ground anchors has many advantages and therefore, it is widely used as the supporting structures in the engineering excavations. However, the design analysis of this system requires complicated hand calculations and is not efficient for the design engineers. This paper presents an improved hand calculation method for estimating of the internal force in the ground anchored reinforced concrete frame. The joint forces in the longitudinal and transverse beams are arbitrarily distributed; then based on the analytical solution for the finite beam on Winkler foundation and the superposition principles, the distribution of the internal force and the ground reaction of the beam on elastic foundation under the action of multiple concentrated forces is obtained. Finally, in the paper, the deformation characteristics of the ground anchored reinforced concrete frame system is evaluated and the simplified the internal force estimation method is summarized.
