| Abstract: | During constructing self-anchored suspension bridge,controlling suspender force is an important problem for bridge to reach rational state after construction. Combining with mechanical characters of self-anchored suspension bridge during construction procedure,an influence matrix method based on geometric linearity and geometric nonlinearity for determining construction suspender force of self-anchored suspension bridge is proposed. Using the method,the calculation is easy and the result is correct. |
