摘要
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。
Five types solution of non-stress length of cable in cable-stayed bridge derived from parabola and catenary theory are analyzed.Non-stress length of cables in two typical real bridge are calculated to illustrate the precision of different solutions.Based on the numerical results,some suggestions are given for calculation of non-stress length of cable.
