摘要
叠合梁的界限受压区高度和最大配筋率是叠合结构中的一个疑难问题.本文对这一问题进行了研究,提出了按平截面假定解决问题的思路及和砼结构设计规范GBJ10—89相互衔接配套的界限受压区高度公式和最大配筋率公式.并将计算结果与试验结果、计算机分析结果进行了比较.
The determination of the balanced depth of the compression zone and the maximum steel ratio in composite beams is an outstanding problem in calculating composite members.The problem is discussed and solved on the basis of plane section hypothesis in this paper.and the formulae derived for determining the depth of the compression zone and the steel ratio of composite beams with balanced section can link up with the Chinese Design Code of Cocrete Structure(OBJ 10-89).The results obtained are in agreement with the existing test data and those calculated by computer.
