摘要
VSLPT PLUS 塑料波纹管 ,因其摩阻系数明显较小 ,故在大跨度桥梁预应力钢束应用中 ,可适当减少配筋 ,节约预应力钢材。
VSPT-PLUS plastic bellow has smaller friction coefficient, so it is used in the prestressed strand of large-span bridge so as to reduce appropriately reinforcement and save the prestressed steel. The paper introduces the application example and the determination of its friction coefficient.
