摘要: 客观、可靠、及时地评定桥梁的承载力对保证其安全营运具有重要的意义.本文应实践需要,从钢筋砼结构设计原理出发,推导出钢筋砼梁桥强度和刚度指标即挠度和钢筋应变间的互换关系式.可靠性分析表明,该公式结果可靠,可望为今后的桥梁承载力评定带来较大的方便.

关键词: 承载力评定, 挠度, 应变, 互换

Abstract: It is important to evaluate bridges' bearing capacity correctly and timely.In this paper, using design principle of steel concrete structure, exchanging relation between strength and stiffness torget of steel concrete T-beam bridges is set up, which is proved to be correct and helpful in practices.

Key words: evaluation on bearing capacity, deflectio n, strain, exchanges
