此外，由于梁纵向有非预应力钢筋和预应力钢筋，且拉、压区用钢量不同，所以钢筋约束不同，对梁的挠度影响较大。
Moreover, due to the non prestressed steel and prestressed steel, and the different amount of using steel in pulling and pressing areas, so the restrain of steel is different.
部分预应力混凝土梁中的非预应力钢筋在反复运行荷载作用下承受交变应力。
The non—prestressed steel bars in ppc beams endure alternate stress under the repeated service loading.
并且为使非预应力钢筋具有与预应力纤维塑料筋匹配的防腐性能，采用先进的环氧涂层钢筋作为非预应力筋。
In order to enhance the corrosion resistance of steel bars, the epoxy coated ones are used as non-prestressing reinforcement.
