【Abstract】 In combination with the tensioning operations of suspenders for zhongshanqiqiao, The Control force of Tensions Supspenders for a spatial Tied-arch bridge were calculated by using the finite element computation programme Asys, with its die and live elements. Influence matrix method and backward sequence method were used during the calculation and the results were match. The paper provides reference for constructions of similarly bridge.更多还原
