不同规程下矩形钢管混凝土抗弯承载力研究
|
摘要
通过国内外钢管混凝土设计规程对有关试验进行了矩形钢管混凝土抗弯承载力的计算,比较了规程之间计算结果的差异。结合典型算例,分析了在不同含钢率、混凝土强度和钢材强度等影响因素下钢管混凝土抗弯承载力的变化趋势,得出了不同设计规程在进行矩形钢管混凝土构件抗弯承载力设计计算时的特点,结论具有一定的参考价值。
Though the calculation results of the bending bearing capacity in rectangular steel tube concrete tests,the difference between the norms is observed and studied.By means of typical examples,the changing trends of the bending bearing capacity of the rectangular steel tube concrete under different steel ratio,different concrete strength and different steel strength are analyzed in detail,and the characteristics of different norms are obtained through the calculation of the bending bearing capacity of the rectangular steel tube concrete.The conclusion is valuable to projects and researchers.
