| 摘 要： | 预应力组合连续梁作为一种更合理的结构,它具有更好的弹性、更高的承载能力、减轻钢材重量以及提高抗疲劳和抗裂性能等优点,逐渐受到结构人员的重视.文章通过对两根预应力组合连续梁的实验研究和分析,建立预应力组合连续梁的裂缝宽度计算公式,以及挠度计算方法,并对计算结果与实验结果进行比较,证明这种计算方法是可行的.

| Abstract: | As a more reasonable kind of structure,the continuous prestressed composite beams have many advantages which are their elastic behavior to higher loads, increased ultimate capacity, decreased self load, the enhanced ability of reducing fatigue and fracture, etc . The expressions of calculating deflection and width of crack are presented in this paper according to the experimental study and analysis of two continuous prestressed composite beams.The calculated results are compared with the test results which shows the feasibility of these expressions. |
