用本文提出的有限条塑性系数增量初应力法分析了钢偏心压杆局部与整体相关屈曲的极限承载力，得到了中截面的屈曲模式，表明大部分的工程实际的压杆均表现出明显的局部屈曲与整体屈曲的相互作用，板件局部屈曲，并不意味着结构整体立即丧失承载力。

Then, safety analysis method was constituted considered the typical damage of concrete beam bridge. 5. By amending the reduction rate of loading capacity used in Code for Maintenance of Highway Bridges and Culvers (JTG H11-2004), a new reliable index is presented in the same safety standard to reflect the relation between load and resistance. According to the basic principal of calibration method, the recommended gradation index was computed under various factors such as different load combinations, vehicle operating status and different failure modes. With these calculated numerical values, the calculated reliability indexes standard for the estimation of safety degree of in-service concrete girder bridge members was ultimately obtained.6. Based on the related standards and results on crack and displacement that cannot continue to loading at home and abroad, the evaluation grade of the concrete beam bridge is proposed by analogy.
