【摘要】 论文针对桥梁带载加固的实际受力情况,分析了两阶段受力的迭合构件的受力特点,模拟两阶段受力,进行小梁试验研究.在此基础上,建立了加筋类两阶段受力迭合构件正截面强度计算公式,提出了可用于桥梁加固设计的实用计算方法.

【Abstract】 In this paper, the mechanical properties of the weak bridge member loaded at two stages, which is considered as a composite member strengthened under loading, are analysed. Test beams are researched to simulate the loading conditions at two stages.Based on the test results, practical calculating method and formulae are proposed.
