Structural Analysis And Research Of Self-anchored And Single-tower Suspension Bridge

Nowadays, self-anchored and single-tower suspension bridge is more and more popular for its beautiful,economic bridge type and smart address. To make sure that the self-anchored and single-tower suspension bridge is safe during its construction and operation period, and make the design of bridge more economic and reasonable. Combine with practical engineering, this paper researched the influence between variation of structural parameter to the structural static and dynamic character. The research content as following:(1) Unifies the finite displacement theory, in view of from anchor type alone tower hanging bridge's stress characteristic, to a span 40.12m+5×40m+30m+350m +30m+30mhas carried on the multianalysis from the anchor type alone tower hanging bridge.(2) Unifies the finite element theory, establishes from the anchor type alone tower hanging bridge's space model, through changes its bridge floor each parameter, carries on the analysis to its self oscillation characteristic.(3) Through the analysis finite element model, through carries on the static state and the dynamic mechanics computation from the anchor type alone tower hanging bridge's some dissimilar structure limiting condition, the limiting condition will carry on to the bridge structure's influence has analyzed effectively.(4) To carried on from the anchor type alone tower hanging bridge's structure under the earthquake resistance coefficient this limiting condition has compared to analyzes. To the tower, the Liang elastic restraint system has conducted the analytical study emphatically.
