| Abstract: | The limit span of two-span self-anchored suspension bridge with single tower is deduced. Some factors,such as ratio of rise to span of main cable,ratio of side-span to main-span,ratio of height of tower to main-span, second dead load and live load, are analyzed in this paper. Based on the common used material and considering the main factors, the limit spans of self-anchored suspension bridges with concrete stiffening girder and with steel stiffening girder,are discussed in detail, and the corresponding limit spans are given. |
