Abstract:
In order to study the static behaviors of super-span suspension bridges with CFRP cables and compare them with those with traditional steel cables, suspension bridges with main span of the 2 000 m and 3 000 m with CFRP cables and steel cables and 5 000 m suspension bridge with CFRP cables were designed respectively. The internal force and deformation under the action of dead load, vehicle load and temperature were analyzed with the finite-element method. The results show that the structural internal force increases quickly with the increase of the span and the larger span, the higher the increase rate. The main cable tension and average suspender force of CFRP cable suspension bridges are less than those of the steel cable suspension bridges with the same span, but the stiffening girder moment of the former is slightly larger than that of the later when they are under the action of dead load. The vertical displacement of the CFRP cable suspension bridges is slightly larger than that of the steel cable suspension bridges when they are under the action of vehicle load. The internal force and the vertical displacement of the CFRP cable suspension bridge are much smaller than those of the steel cable suspension bridges when they are under the action of temperature. 2 tabs, 11 figs, 13 refs.
