Abstract

Curve suspension bridges, with their unique design, are often used for scenic bridge construction. A prime example is the Shanghai Disneyland Curve Suspension Bridge and the Hemei Bridge on the Xiamen Mountain-Sea Health Trail. During the construction of such bridges, the impact of temperature effects is often overlooked. In fact, the temperature effect under the influence of annual maximum temperature differences cannot be underestimated. Studies have shown that the temperature effect on cable forces is comparable to the second-phase constant load effect and significantly impacts the maximum principal stress at mid-span. Taking the Hemei Bridge as an example, through the establishment of finite element models and parametric analysis, the optimization effects of different geometric parameter adjustments on temperature effects were verified: tower height adjustments significantly affect the temperature effects on suspension cables, main cables, and connecting cables; adjusting the radius of curvature of the curved beam can effectively improve the stress distribution at mid-span suspension cables and the ends of the main beam. Adjusting the length of the connecting cable to enhance the temperature effect of curve suspension bridges is also feasible. The research findings in this paper provide theoretical basis and technical support for the analysis and design optimization of temperature effects in curve suspension bridges.
