摘要
对工字钢为对称放置的四个不同钢骨含钢率、纵筋配筋率的钢骨混凝土梁进行了抗弯实验。根据试验结果与理论分析对不同用钢量的钢骨混凝土梁进行了对比、分析,讨论了国内外几种受弯承载力计算公式,认为合理的含钢率为5%～8%,在合理的含钢量范围,构件的抗弯能力与含钢率成正比。
Four steel reinforced concrete beams with different steel ratios are tested. The flexural behaviors of such structural beams are analyzed with test and theory and several flexural strength equations are also discussed. It is shown that the flexural strength is higher with the increasing of steel ratio, the test results are more closed to the calculation results, the reasonable steel ratio is between 5% and 8%.
