| 摘 要： | 为了研究方钢管混凝土柱的粘结滑移性能,进行了9个不同长细比、宽厚比的方钢管混凝土柱的推出试验。通过测量荷载、加载端和固定端的钢管与混凝土滑移,并根据试验结果得出了典型P-s曲线,分析了影响方钢管混凝土粘结强度的主要因素,可对方钢管混凝土粘结滑移性能的进一步试验研究和理论分析提供参考。

| Abstract: | In order to study the bond-slip properties between square steel tubes and concrete,9 push-out tests of concrete-filled square steel tubes(CFST) with different specification were carried out.In the push-out tests,the strains of square steel tubes and the local slip were both measured by experimental method,and the classic P-s curves of the experimental results were obtained,the factors of effect on the bond strength were also analyzed.It will be helpful for the further experimental researches on the bond-sli... |
