一、研究背景
随着现代建筑结构不断向超高和大跨方向发展,对承重构件的承载力和延性提出更高要求,常在传统钢管混凝土中配置钢管、钢筋和型钢等部件,以满足构件在受力和施工性能等方面的需求。双钢管混凝土(Concrete-filled double tube, CFDT)是在钢管混凝土中配置钢管形成的一种组合构件(如图1),目前关于CFDT构件的研究多为短柱的轴压性能,对于长柱的研究十分有限。因此,本研究通过试验和有限元对CFDT长柱的轴压和偏压性能进行分析。
二、试验结果与讨论
进行了16个长柱的轴压和偏压试验,包括14个CFDT试件和2个CFST试件,考察参数包括内钢管比率(通过内钢管的直径和壁厚控制)、加载方式(轴心加载和偏心加载)、长细比(36.0~50.4)和截面形式(圆和方截面),试验加载装置如图2所示。试验结果表明CFDT试件产生整体弯曲破坏(如图3),方试件的外钢管产生局部鼓曲变形,内钢管的存在使得CFDT试件较CFST试件展现出更好的混凝土完整性和更高的承载力(如图4)。
此外,CFDT试件的极限承载力随着内钢管比率的增加逐渐提高,总含钢率相同时,CFDT试件的极限承载力较CFST试件更高(如图5),如试件CCS2-1(to=3mm)的极限承载力较试件CFST2(to=4mm)高7%。对于相同截面的CFDT试件,其极限承载力随着长细比的增加逐渐降低,且长细比的变化对偏压试件的承载力影响更明显。
三、有限元分析
为明晰CFDT长柱在轴压和偏压荷载作用下的受力机理,扩大参数研究范围,采用有限元软件ABAQUS建立了CFDT轴压和偏压长柱的有限元模型(如图6),通过试验结果对模型的准确性进行验证。试验与模拟的极限承载力之比的平均值为1.032,相应的均方差为0.058,有限元模型也很好地预测了钢管的弯曲变形和混凝土的破坏(如图7)。
基于建立的有限元模型,分析了CFDT长柱在轴压和偏压作用下的受力机理,包括典型的全过程N-Δ曲线(如图8)、截面应力分布(如图9)和相互作用力发展(如图10),其中圆柱CFDT-C1为轴心加载,方柱CFDT-S1为偏心加载(偏心距e=70mm)。
分析结果表明:外部混凝土达到峰值荷载时CFDT长柱达到其极限承载力,外部钢管和混凝土早于内部钢管和混凝土破坏,下降阶段内部的CFST部件仍展现出良好的承载能力,整个过程中内部钢管和混凝土之间的相互作用较外部钢管和混凝土更强。
基于典型算例研究了影响方CFDT偏压长柱承载力的关键参数(如图11)。结果表明:外钢管强度、混凝土强度、长细比和荷载偏心率对柱的极限承载力影响显著,而内钢管强度和内外钢管直径比变化对极限承载力影响较小。
四、结论
Conclusions
1
试验结果表明CFDT试件的破坏形态与CFST试件相似,内钢管的存在使得CFDT试件较CFST试件展现出更好的混凝土完整性和更高的承载力。
2
CFDT长柱的极限承载力随着内钢管比率的增大而增加,随着长细比和偏心距的增加而减小,建立的有限元模型可以很好地预测试验结果。
3
外部混凝土达到峰值荷载时CFDT长柱达到其极限承载力,外部钢管和混凝土早于内部钢管和混凝土破坏,下降阶段内部CFST部件仍展现出良好的承载能力。
