| 摘 要： | 该文通过T梁的计算实例,分析了2004版桥梁规范与1985版规范在钢筋混凝土受弯构件裂缝宽度验算上的异同点,并通过数据归纳总结变化的特点和规律,发现2004版规范通过荷载组合方式的变化,对裂缝提出了更为严格的要求。同时,验证2004版规范对结构耐久性更加关注和重视。

| Abstract: | Through the computing example of Tee-beams, the article analyzes the similarities and differences in checking the cracks width of the reinforced concrete bending members between the bridge specifications of 2004 version and 1985 version. After summing up the changes in the characteristics and laws by the data induction, the article finds to put forward the stricter requirement for the cracks by means of changing the combination in the load in 2004 version. At the same time, the article verifies that the dur... |
