【摘要】 基于体外索的弹性应变能量守恒,根据发生滑动的体外预应力索段的无应力索长不变,提出了一种简化体外索与转向块相对滑移的计算方法,并用算例对该方法正确性进行了验证,证明该方法具有良好的计算精度,可供采用非线性理论研究体外预应力结构提供参考。更多还原

【Abstract】 According to elastic strain energy conservation of exterior cables, i.e., the length of non\|stressed cable remains unchanged, a simplified computation method for relative sliding of exterior cable and turning block was put forward, which was verified through computation cases. The method proves excellent accuracy, and providing reference for studying exterior prestressed structure by non\|linear theory.更多还原
