摘要
叙述截面效率指标的力学定义和工程实用中的物理意义。分析在翼板湿接T形截面情况下,现行截面效率指标计算方法存在的缺陷,提出精确的计算方法。结合实例对比分析翼板T形截面两种截面效率指标计算结果的差异;计算分析T形截面尺寸变化对原计算方法误差的影响程度。
The paper expresses the methanic meaning and physical meaning of section efficiency index in application, analyzes the defects in existing computation method and puts forward a kind of new computation method to make the computation results correct. The paper also analyzes the results＇ differences of two computation method for wet joint web plate section and affection degree of size alteration to exsiting computation method.
