| 摘 要： | 该文对双预应力混凝土足尺梁进行了试验研究，测出了双预应力混凝土梁在受载后的应变和挠度，并用有限元素法进行了分析计算。研究结果显示，双预应力混凝土足尺梁具有良好的受力特性，能够有效地降低梁高，并且在正常使用阶段比普通预应力混凝土梁有更好的工作性能。

| Abstract: | The behavior of the bi prestressed beam was experimentally investigated,the strain and deformation of the beam were measured and analyzed by means of the finite element method. The results indicated that bi prestressed concrete beam had more advantageous properties than that of the common prestressed concrete beam in the normal working stage.The height of beam could be reduced effectively. |
