钢—混凝土组合结构中剪力连接件承载力的比较

Comparison of the loading capacity of shear connectors in steel-concrete composite structures

随着建筑技术的发展,钢—混凝土组合结构应用得越来越多,而剪力连接件是这类结构的关键部位,对其计算显得尤为重要。本文比较了钢—混凝土组合结构中几种常用的剪力连接件,分析了它们的抗剪强度和疲劳抗力,比较了不同国家或研究者给出的计算公式之间的差异,最后得到了几点有用的结论。

With the development of technology of constructions, more and more steel - concrete composite structures have been built. Because the shear connector is the key part of this type structure, how to calculate it is very important. Several different types of shear connectors in common use are compared in this article, both the capacities of shear strength and fatigue resistance are discussed. And the comparison of different formulae given by different countries or different investigators are also studied in this paper. Several conclusions are obtained at last.
