对比分析了基于抛物线、悬链线理论的五种斜拉索无应力长度的计算方法,用两座有代表性的实桥算例分析了各种斜拉索无应力长度解的精度。根据计算结果给出了斜拉索无应力长度的计算建议。
Comparisons and analyzes of five kinds of calculation methods of no-stress length of stay cables based on parabola and catenary are carried out. Two representative examples of real bridges are used to analyze the accuracy of stress-strain length solutions. According to the calculation result, the calculation suggestion of the cable length without stress is given.
