摘要
本文通过钢筋轻骨料混凝土两跨连续梁的试验,对其受力性能、调幅值、极限荷载、截面M—φ关系以及变形等同题进行了分析研究,提出了调幅值δ与受压区相对高度的关系曲线,可供设计采用。本文还编制了非线性全过程分析程序,计算机运算结果与试验值符合程度令人满意。
In this paper,the behaviour of loaded beam,the amplitude of moment modulation, the ultimate load,the moment - curvature relationship, the influence of loading types , and the deformation are studied through the tests of reinforced lightweight aggregate concrete two - span continuous beams. The δ-ξcurve is given, which is useful to designers. The computer program for non - linear full -range analysis has been developed. The results computed agree well with the test values.
