| 4. | The stress contribution in the cross - section is uniformity , and i - shaped steel in web space can result in reduction of stresses , when the concrete was filled into the new dumbbell
进行了14根钢管混凝土哑铃形试件的偏压试验，其中腹腔内不填充混凝土的构件6根和腹腔内填充混凝土的试件8根。 |
| 5. | The hit spot of elliptic shape appeared on crystal plane paralleling to c axis , and one half was brighter than the other half under sem . the brighter part was the negative pole , and the darker one was the positive pole
自发极化大的电气石在平行于c轴的晶面上出现“哑铃形”或长的“椭圆形”明暗对比的打击斑，在垂直于c轴的端面上则出现无明暗对比的斑点。 |
| 6. | The methods of modificatory lattice cross - section and equivalent circular cfst cross - section for calculating the maximum load of dumbbell cfst columns with eccentric loading were presented in this paper . the ultimate strength of 14 specimens were calculated by the two methods were close to experimental results . finally , the two methods were used to calculate the ultimate strength of arch bridge of zhengzhou yellow river highway
对现有钢管混凝土哑铃形构件极限承载力的计算方法进行了分析，在此基础上，提出了计算钢管混凝土哑铃形构件的偏压极限承载力的修正的格构式截面法和等效截面法，两种算法的计算结果与试验值均吻合较好，最后用这两种算法计算了郑州黄河公路二桥拱肋的极限承载力。 |
| 7. | Stress analysis on cross - section of traditional dumbbell cfst arch rib which concrete filled into the web space and new dumbbell cfst arch rib which concrete not filled into the web space during the concrete was filled into the inner space are introduced in this paper . analysis expressing the stress in the two connecting points of the web plates and the bottom steel tube of the traditional dumbbell is very large when concrete is filling into the web space , and easily causing some great cracks occurred in the weld sealing , which should causing the engineering field
对钢管混凝土哑铃形拱肋以及新型哑铃形钢管混凝土拱肋在浇注混凝土时的截面应力分布进行了分析，结果表明传统哑铃形截面(腹腔内填充混凝土)在灌注腹腔混凝土时，钢管与腹板交接处将产生很大的应力，容易引发爆管事故，应引起工程界的注意；新型哑铃形截面(腹腔内不填充混凝土而用工字钢加劲)灌注管内混凝土时，截面的受力情况较好，能避免爆管事故的发生，且能简化施工，降低拱肋的自重。 |
| 8. | Total of 14 dumbbell cfst columns were tested under eccentric loading , those with 6 specimens which concrete filled into the web space and those with 8 specimens which concrete not filled into it . experimental results indicate that , the portrait strain on the middle section of two type specimens keep on the plane with each loading . the maximum load of columns which concrete not filled into the web space is lower than those filled into it
试验结果分析表明，两组试件的中截面纵向应变分布在不同的受荷阶段基本能保持平面；腹腔内不填充混凝土的哑铃形柱的极限承载力比腹腔内填充混凝土的哑铃形柱的极限承载力略小，但差值不大，且这种差值随着偏心率的增大而减小。 |
