| Abstract: |
| Based on the fundamental theory of computation of the cable\|prestressed steel trusses established in paper[1],the iterative perturbation formulas which inversively determine the stiffenesses of elements of steel trusses and cables with the restraint of vertical displacements of the truss are put forward on matrix perturbation principle. Some computational examples show that the methods presented here has higher accuracy, and can meet the need of engineering design. |
