摘要:
为研究圆钢管型钢再生混凝土组合柱的偏压力学性能,进行了14个组合柱强轴单调偏心受压试验,观察了试件的偏心受压破坏过程及破坏形态,分析了设计参数对试件荷载-位移曲线、荷载-应变曲线、侧向挠度及承载力等偏压性能指标的影响规律。结果表明,组合柱偏心受压破坏始于受压侧中部型钢屈服,随后钢管受压侧达到屈服强度,进而核心再生混凝土被压碎,钢管中部出现局部明显鼓曲,最终导致试件丧失承载力;组合柱的偏压承载力分别随着再生粗骨料取代率和钢管径厚比的增加而逐渐降低;适当增大型钢配钢率可有效提高试件的偏压承载力和变形能力;增大偏心距和长细比对于组合柱的偏压承载力是明显不利的;总体上,圆钢管型钢再生混凝土组合柱具有较高的偏压承载力和良好的变形能力。
Abstract:
To investigate the mechanical properties of profile steel-recycled aggregate concrete filled circular steel tube columns under eccentric compression loads, 14 static loading tests of composite columns under eccentric compression loading were performed in this paper. The failure process and failure mode of specimens under eccentric compression loads were observed. The influence of different design parameters on load-displacement curves, load-strain curves, lateral deflection deformation and bearing capacity of columns were established and analysed in detail. The results showed that the failure of columns began with the yield of the profile steel in the middle of the compression side, and then the yield strength of the circular steel tube was reached at the compression side. After that, the core RAC was crushed, and local buckling occurred in the middle of the circular steel tube, thereby resulting in the loss of the eccentric bearing capacity of the columns. The eccentric bearing capacity of columns decreased with the increase in recycled coarse aggregate replacement percentage and the diameter-thickness ratio of circular steel tube. Addition, the properly increase in steel ratio was favorable for improving the eccentric bearing capacity and ductile deformation capacity of specimens, but the deformation capacity of specimens decreases gradually. Meanwhile, the increase in eccentricity and slenderness ratio was disadvantageous to the eccentric compression performance of composite columns. In summary, the columns generally show good ductile deformation capacity and high eccentric bearing capacity.
