摘要： 为了进一步研究钢管-钢骨高强混凝土构件抗弯承载力极限状态的力学性能,根据中和轴的位置不同,将破坏模式分为多种情况,采用改进的叠加方法计算了矩形钢管-钢骨混凝土受弯构件的正截面承载力,给出了工程中典型的破坏模式,即钢管受压、受拉区均屈服、钢骨受拉区屈服的承载力计算公式.该方法克服了简单叠加法和一般叠加法在计算上的明显缺陷,计算精度较高,得出的承载力计算公式可为工程应用提供理论参考.

Abstract: To study further the ultimate flexural capacity of a steel tube member filled with steel-reinforced high-strength concrete, its failure is divided into several modes according to the different positions of neutral axis. Then, an improved superposition method is introduced in the calculation of the cross-sectional bending capacity of flexural members of the rectangular steel tube beams filled with steel-reinforced high-strength concrete and the formula for typical failure mode is given to calculate the bending capacity in tensile region under conditions that both compressional and tensile region have yielded. The new method overcomes the shortcoming of simple and conventional superposition methods in calculation, which provides higher precision and the formula proposed can offer reference for engineering practice.
