Study and application of bearing capacity and stiffness of supportingpoint of slop strut

The common styles of supporting point of slop strut used in Shanghai are introduced. Based on the analysis of its force transfer path, bearing capacity and deformation mode, the mechanism of interaction between soil and supporting point is discussed. A simplified method for calculating the horizontal bearing capacity and stiffness of supporting point of slop strut is proposed based on the assumption of rigid supporting point. A case is employed to validate the above method. The engineering practices prove the reasonableness of the proposed method.
