摘要
对钢-混凝土双面结合梁截面从开始加载到破坏的全过程进行分析,分析中考虑了混凝土开裂、材料非线性及滑移效应等影响因素。编制了用于计算M-φ曲线的数值迭代程序,此程序也适用于钢-混凝土单面结合简支梁和连续梁截面。通过算例,对双面结合梁截面受弯全过程的M-φ曲线进行了分析讨论,并与传统的单面结合梁进行了比较分析。
The whole process from loading to destruction of a double steel-concrete composite beam seetion is analyzed,in which the cracking of concrete, yielding of steel, stiffness of shear connectors and interface slip are taken into account. A numeral iterative program is drawn up for the calculation of the bending moment-sectional curvature curve that is not only suitable for the double steel-concrete composite beam, but also for the traditional composite heam. Some M-ψ curves are calculated and analyzed in the examples, and compared with the traditional continuous steel-cocrete composite beams.
