摘要/Abstract

摘要： 针对钢管再生混凝土柱组件的非均匀轴向受力的复杂性,提出了非均匀轴向受力的精确建模与仿真,分析了轴向受力的均匀和非均匀条件下的力学性能,构建了组件的三维和压力模型。分析了几何参数、受力和变形等因素对承载力的影响。仿真与试验结果较吻合,均匀轴压承载力大于非均匀承载力,偏心轴压的承载力与偏心距相关,非均匀轴压的承载力高于偏心轴向承载能力。研究表明,参数选择和受力情况对承载力影响较大,结果验证了计算方法和模型的有效性。

Abstract: According to the complexity of non-uniform axial force on recycled aggregate concrete confined by steel tube column, precise modeling and simulation on non-uniform axial force were put forward, mechanic properties of axial force under uniform and non-uniform conditions were analyzed, and its three-dimensional model and force model were established. Then impact of load capacity was analyzed, such as geometric diameter, loading condition, and deformation during production. Force simulation and experimental results fit relatively well. It turned out that uniform axial load capacity was greater than concentrated eccentric axial load capacity. Besides, eccentric axial load capacity was related to eccentricity. Moreover, it could be singled out that non-uniform axial load capacity was greater than concentrated eccentric axial load capacity. The research demonstrates that variation in parameter selection, different force conditions have relatively high influence on load capacity of components. The results verify the validity of calculation approach and model.

Key words: recycled aggregate concrete, non-uniform, axial force, precise modeling, simulation
