| 1. | Experimental study on strengthening beam by externally - prestressed - cable - offloading method 武黄公路桥面改造铺装混凝土试验研究 |
| 2. | In order to study reinforced effect and to know reinforce mechanism , this paper investigates on 6 non - strengthened beams and 15 strengthened beams 为了研究加固效果、认识加固机理,本文对6根未加固钢筋混凝土梁和15根加固钢筋混凝土梁进行了试验研究。 |
| 3. | By this program and experimental data , the author analyzes the strengthening theory and the cross - section ' s bending resistance capacity of strengthened beam 并利用此程序和试验数据对预应力加固梁及粘钢加固梁的加固原理和正截面应力状态进行了探讨。 |
| 4. | Finally , by the experimental data and the programming calculation , the author study the eccentric compression and tension state on the control section of the two style of strengthened beam 最后,根据试验数据和程序计算数值对预应力加固的控制截面进行偏心拉压分析。 |
| 5. | According to the experience of the writer ' s perennial work , sum up the prince - pies of reinforced concrete ' s structural members , and introduce some methods to stiffen and strengthen beams pillars and boards 作者根据多年鉴定工作经验,总结混凝土构件的补强加固原则,详细介绍了梁、柱、板的一些补强加固方法。 |
| 6. | The relation between the strain , stress , stiffness of the beams and the load is described . the author also analyzes and describes the factors that affect the resistance capacity of the strengthened beams 对于梁在加固后加载时梁的应变、应力、刚度与荷载的关系;影响加固后梁的承载力的因数进行了分析和介绍。 |
| 7. | At last , finite element analysis ( fea ) is done by using software ansys , and the fea results indicates that the cfrp increases the ultimate flexural capacity of the strengthening beam . all these agree with the test results 最后,利用ansys分析软件对加固梁进行了模拟分析,表明加固梁的抗弯极限承载力得到了提高,与试验结果是一致的。 |
| 8. | But because there are shearing stress and removing stress on the gluing plane between the steel plates and concrete , the phenomenon of premature removing of the steel plates in the strengthen beams is easy to take place 但是,由于钢板和混凝土粘结面上存在粘结剪应力和剥离拉应力,使粘钢加固梁容易发生钢板端部和弯剪区段跨中的早期剥离破坏现象。 |
| 9. | Third , the paper theoretically analyzes basic design theory of flexure strengthened rc beam . the model and mechanism of debonding failure for strengthened beam are explored primarily . at the same time , the maximum and 然后,论文从理论上分析了抗弯加固设计的基本原理;初步探讨了混凝土加固梁两种粘结剥离破坏模型及其破坏机理;通过理论分析首次提出了最大贴布率的概念。 |
| 10. | The characters of the load are described when the concrete beams are strengthened with cfrp . according to the beam ' s character of secondary load , this article theoretically analysis the flexural resistance capacity of the strengthened beams 对进行碳纤维布加固混凝土梁以提高正截面承载力力时的受力特点进行了描述,根据其二次受力特点对梁在加固后的承载力进行了理论分析。 |
