| 3. | When the ductility of steel bar is bad , the ductility of section will be bigger with the improvement of the ductility of steel bar
钢筋延性较好，则构件截面延性随截面相对受压区高度的减小而增大；钢筋延性较差，则构件截面延性由钢筋延性控制。 |
| 4. | Then limiting load is decreased . ( 6 ) horizontal load can increase the coefficients of the modulation of moment when value of is little while decrease it when is large
( 6 )在中支座截面相对受压区高度较小时，有水平荷载的框架其弯矩调幅系数要大于只有竖向荷载的框架。 |
| 5. | The following conclusions are reached . ( 1 ) the relative height compressive zone of section or the axial force is bigger , the rotational capacity of the section is weaker
得出了以下主要结论： ( 1 )截面相对受压区高度、截面所受轴力显著地影响预应力框架梁截面的延性。 |
| 6. | ( 5 ) horizontal load can increase the bearing ability of the section and the limiting load of the frame when value of is little . however , horizontal load can generates axial force and then deceases the ductility and bearing ability when is large
( 5 )在中支座截面相对受压区高度较小时，水平荷载在框架梁中产生轴力，提高截面的承载力，极限荷载也随之提高。 |
| 7. | The paper has concluded the fundamental principle of sticking reinforcement . that is to improve the ultimate flexural capacity of the original reinforced concrete beam through externally bonded with high - strength tension materials
本文总结出粘贴加固的基本原理：通过粘贴高强的抗拉材料，进而使得受弯构件的受压区混凝土高度增加，从而提高原钢筋混凝土受弯构件的正截面承载力。 |
| 8. | ( 3 ) the relative height compressive zone of section greatly influences the redistribution of internal force of the prestressed frames . the total modulation of moment decreases according as the increase of relative height compressive zone of section
随着中支座截面相对受压区高度的增大，次弯矩增大，次弯矩调幅增大，但荷载弯矩调幅以更大的幅度下降，导致总的弯矩调幅下降。 |
| 9. | 2 . the effect of frp reinforcement ratio on the ultimate moment of frp reinforced concrete beam is studied , the conclusion is that the ultimate moment increases with the increase of the reinforcement ratio for frp reinforced concrete beam in a certain range of reinforcement ratio
结果表明，对纤维增强塑料筋混凝土梁，在配筋率的一定范围内，配筋率越大，受压区面积越大，极限抗弯承载力越高。 |
| 10. | 2 ) the secondary moment is an important factor on moment modulation . when is small , influence of the secondary moment on moment modulation is small . contrary , when is high , influence of the secondary moment is important
（ 2 ）次弯矩的调幅作用非常明显，当相对受压区高度较小时，次弯矩对调幅的影响作用也小；反之，当相对受压区高度较大时，次弯矩对调幅的影响作用越大，有时，甚至起控制作用。 |
