摘要
提出了一种考虑悬索结构在中支座存在滑移时的非线性计算方法,推导出关于索元无应力长度发生变化时的滑移刚度公式,并进行了实例计算。计算结果表明,本文的方法正确,计算精度满足实际工程要求,并能使计算工作量大大减少,可供悬索结构设计、施工时参考。
Based on the nonlinear elastic analysis, a nonlinear method was presented for calculating the continuous cables sliding at the middle supportings. Meantime, three examples were computed with this method. The results show that the method presented has a good precision and can meet the needs of the practical engineering.
