Abstract

Abstract

A spline finite point method for geometrically nonlinear analysis of arch structure is presented. With the displacement componentsuandwtreated as fundamental unknown variables, and the cubicB spline functions as displacement functions, the nonlinear stiffness equations of spline discretization are established based on the principle of minimum potential energy, and the precise explicit expression of the nonlinear tangential stiffness matrix is derived.
