新型外包钢—混凝土组合梁中栓钉应力分析

Stress Analysis of Bolt in New Type of Steel-Encased Concrete Composite Beams

新型外包钢——混凝土组合梁强度高、延性好、便于施工,应用前景广阔。目前对这种新型外包钢—混凝土组合梁中栓钉应力研究并不是很充分,应用有限元软件对一根新型外包钢—混凝土组合梁中的栓钉的应力分布进行了模拟分析计算,为进一步研究新型外包钢—混凝土组合梁中栓钉的布置和应用提供了理论基础。

New type of steel - encased concrete composite beams possess advantages of high capacity, good sta- bility and ductility, convenience for construction and bright prospect of application. However, research of bolt stress is not sufficient. This paper makes a simulative analysis of bolt stress in this new type of steel - encased concrete composite beams by using finite element software ANSYS, which provides applied theoretical basis for more study of bolt layout and the application in new type of steel - encased concrete composite beams.
