摘要
预应力混凝土梁的挠度与预应力、荷载等有关 .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 .提出了因纵向钢筋的影响引起的挠度计算方法 。
The method for the deflection of prestressed concrete beam due to different amounts compression and tensile steel.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.The results computed by this method are compared with the test data.
