摘要
本文在文献[1]的基础上,着重介绍20根钢管混凝土试件的简支架试验结果。论述了钢管混凝土组合材料研究模型选取的依据;探讨了剪跨区内应力应变分布变化规律;分析了试件的破坏过程及状态。为进一步的理论分析提供了依据。
Based on Reference[1], this paper mainly describes the results of 20 simple beam experiments of concrete filled steel tubes in detail. The choice of research model is discussed for the composite material of concrete filled steel tubes. This paper explores the regularities of the distributions of stresses and strains within the shearing spans and analyses the failure procedures and the failure modes of the specimens. Thus it provides a basis for further theorefical analyses.
