Abstract

A practical method to calculate the prestressing forces of suspendome structures using force method is put forward in this paper. For a suspendome structure having n hoop cables, n control points can be selected. A system of linear homogeneous equations with n unknown cable forces can be obtained through the vertical displacements of n control points under the vertical loads and each hoop cable’s unit prestress. The coefficients of the equations can be obtained through FEA software using force method principle. In the end, a numerical example is given to describe the calculating process and verify the validity of the proposed method
