大跨度CFRP缆索悬索桥的静力性能
Study on static mechanics of long span suspension bridge with CFRP cable
摘要
Abstract
This paper proposes an analysis method for the static mechanics of suspension bridges based on segmental catenary and FEM software. A comparative research on mechanics of suspension bridge with a span of 2 000- 5 000 m is conducted according to the proposed method, and CFRP suspension bridges are proved advantageous and practicable. A parametric study for the deflection performance of 2 000 m CFRP suspension bridge is executed in order to enhance its stiffness, where the span arrangement, rise to span ratio, side to main span ratio, inertia of girder and tower, and the central buckle are considered, respectively. A serials of design suggestions for improving the structural stiffness are proposed.关键词
