摘要
为研究钢-混凝土组合梁在静载作用下的力学性能,建立一个考虑栓钉滑移及钢筋作用的有限元分析模型;结合算例对开/闭口组合梁的抗弯性能,裂缝发展趋势及分布特征进行比较,混凝土及钢梁的应力-应变关系曲线计算结果与输入曲线吻合良好。
A model of the finite element analysis considering the slip effect of stud and the function of steel bar is established in order to research the mechanical properties of steel-concrete composite beams under static load. It is conducted a comparison between composite steel-concrete beams with open section and those with box section about ftexural performance,development trend and distribution characteristic of cracks. The curves of strain and stress of concrete and those of steel beams are anastomotic with the curves of theories.
