The mechanical behavior of steel webs with negative bending was studied with combined stress loads of flexure, axial pressure and shear to prevent local buckling in continuous composite beams.

For rail anti-slide piles, the bending moment, normal stress and anti-slide force of rail anti-slide pile are calculated inversely based on flexure deformation measured by inclinometer.

By introducing the boundary conditions of the circular plate, the flexure displacement, radial rotation Angle, radial bending moment and radial shear force on each nodal line of the plate were given.
