| 2. | Design method of moment - strengthening on tension side when load un - removed 非卸载条件下受拉区加固梁的抗弯设计法 |
| 3. | Technique of making strength for crack to pulling part of reinforced concrete beam 钢筋混凝土梁受拉区开洞裂缝补强技术 |
| 4. | A crack in the tension zone of the concrete implies that some slip has occurred between the steel reinforcement and the surrounding concrete 在混凝土受拉区出现裂缝意味着钢筋与周围的混凝土之间产生了一些滑移。 |
| 5. | It is because the clinker is distributed much more in tensile area which bears more stress . for example , with linear and parabolic component gradient variation of aggregates , linear component gradient variation of aggregates reinforces higher than parabolic variation 骨料梯度分布时富熟料侧分布于受拉区,承受较大应力,使得总体强度上升,尤其抗弯强度的变化幅度较大。 |
| 6. | Through experiment this paper compares the crack load of concrete slab with liter polypropylene fiber and glass fiber , and compare with the numerical value of theory . in the calculation assume str ess figure of the extension area is triangle or rectangle 通过试验研究对比了在混凝土板中掺入聚丙烯纤维或玻璃纤维后开裂荷载的变化情况,并与理论计算值进行比较,在理论计算中假定受拉区应力图形为三角形或矩形两种情况。 |
| 7. | When the reinforced glass fibers ( gf ) gradient distribution , the same reinforced role can be achieved in the lower volume of the reinforced fibers , because the distribution of the r einforced fibers is coincident with the stress distribution of the specimen 纤维梯度分布,增强纤维较多的分布于受拉区,纤维的分布更符合材料(构件)的受力方式。在承受最大弯拉应力部位,梯度分布的纤维含量比均匀分布高,因此梯度分布比均匀分布对抗弯强度的提高更明显。 |
| 8. | Based on the destructive test of certain old pre - stressed concrete hollow slab after structural strengthening by cfs , the destructive mechanism and ultimate bearing capacity of old pre - stressed hollow slab after structural strengthening is being researched , which is useful for the strengthening design of old bridge and solvating of single slab problem 摘要通过某已使用10年的旧桥预应力混凝土空心板受拉区碳纤维布加固后的破坏荷载试验研究,对受拉区加固后的旧桥预应力混凝土空心板的破坏机理、变形性能及极限承载能力等进行了研究,为旧桥预应力混凝土空心板的加固设计及单板受力问题的分析解决提供了试验依据。 |
