| 摘 要： | 针时各国规范对混凝土构件的裂缝宽度计算方法纷繁复杂及对闭口箱型构件的裂缝宽度计算仍无章可循的局面,基于不同的裂缝宽度计算理论,对比分析了各国混凝土设计规范中关于开口截面裂缝宽度计算公式的参数;结合实际工程的典型钢筋混凝土箱梁桥,分别按各国混凝土设计规范的计算公式预测其裂缝宽度,并与箱梁桥的裂缝实测值进行比对,分析结果差...

| Abstract: | Calculation formulas for crack width of concrete members in the standards of different countries are different from each other,and calculation method for crack width of closed section members(such as box girder) could not be founded in any criterion currently.In terms of different computation theories of crack width,comparative analysis of parameters in calculation formulas of crack width of open cross-section members in the standards of different countries was performed.Then,a typical reinforced concrete b... |
