摘要

摘要: 为研究常温下圆铝管混凝土柱的界面黏结性能,考虑了混凝土的强度和铝管混凝土柱界面黏结长度两个因素,对圆铝管混凝土短柱进行了推出试验,获得了试件荷载-滑移相关关系、不同荷载下的铝管纵向应变分布规律,分析了现有的钢管混凝土柱黏结滑移本构模型对于评估圆铝管混凝土柱峰值黏结强度和剩余黏结强度的可行性。研究结果表明:各试件荷载-滑移曲线趋势基本一致;铝管表面的纵向应变与其到加载端之间的距离总体呈正比例,黏结应力沿界面长度均匀分布;混凝土强度、界面黏结长度减小都会导致界面黏结强度降低,且受到混凝土强度的影响程度更大。在此基础上,提出了适用于常温下圆铝管混凝土柱界面黏结强度的计算公式。

Abstract: In order to study the interface bonding performance of concrete-filled aluminum tubular columns at room temperatures, three factors including concrete strength and component slenderness ratio were considered. A bond-slip push-out test was conducted on concrete-filled aluminum tubular stub columns, and the load-slip correlation, and longitudinal strain distribution of aluminum tubes under different loads were obtained. The feasibility of existing constitutive models for bond-slip of concrete-filled steel tube columns in evaluating the peak bonding strength and residual bonding strength of concrete-filled aluminum tubular concrete columns was analyzed. The research results indicated that the trend of the load-slip curve of each specimen was basically consistent; the longitudinal strain on the surface of the aluminum tube was proportional to its distance from the loading end, and the bonding stress was uniformly distributed within the interface length range; the decrease in concrete strength and interface bonding length would lead to a decrease in ultimate bonding strength and residual bonding strength, and the impact of concrete strength was greater. On this basis, a calculation formula for the interfacial bonding strength of concrete-filled aluminum tubular columns at room temperatures was proposed.
