摘要
通过试验 ,分析了体外预应力筋在整个加载过程中的应力变化。考虑到体外预应力结构的特殊性 ,特别是体外预应力结构中预应力筋的位置以及预应力筋分析的复杂性 ,提出了预应力筋在转向块处的摩擦模型 ,并且将此模型应用于体外预应力梁的预应力筋分析中。结果证明 ,本文所选用的摩擦模型以及利用非线性有限元方法能够较为合理与准确地解决相关的问题。
With experiment the author analyse the changes of the tendons of externally prestressed beams throughout the loaded process.In consideration of the peculiarity of externally prestressed structure,expecially the location of tendons in externally prestressed st ructure and the complexity in the analys is of prestressed tendons,here the autho r bring out a mode of prestressed tendon s near the deviators,and the author test ify that with mode and in connection wit h nonlinear finite element method we can solve this problem and other problems t hat have some connection with it.
