一、研究背景
柱结构作为主要的承重构件，在建筑结构中起到至关重要的作用，高温作用下柱的破坏则会引起梁、节点及整个框架的失效和倒塌。目前，对结构抗火性能的研究多集中在仅考虑升温阶段构件发生破坏的耐火性能，著名的Cardington火灾试验及2003年湖南衡阳大厦在火灾降温过程中发生突然坍塌等典型事故表明，结构即使在火灾升温过程中没有受到破坏，在降温阶段可能由于抗力的进一步降低而破坏；整体结构中，降温段构件内部产生的温度内力以及内力重分布，对结构能有重要影响。因此，进行结构火灾后性能的准确评估时，需考虑结构所经历的温度和荷载作用历史。内配型钢钢管混凝土(SRCFST)柱近年来在高层及超高层建筑中有广泛应用，本文对该类组合柱构件在考虑荷载及升、降温火灾全过程作用后的剩余力学性能进行试验及研究，以期为结构在火灾后的修复和加固提供指导。
二、试验设计
本文设计加工了6个SRCFST柱试件，进行考虑全过程火灾作用后SRCFST柱剩余力学性能试验，其中3根为方形试件，3根为圆形截面试件，所有试件均承受轴向荷载作用，试件设计如图1所示。为准确评估升温时间对火灾作用后力学性能的影响，以耐火试验得到的耐火极限tR作参考，定义升温时间比t0（t0=th/tR，其中th为升温时间）。
韩林海提出一个完整的时间-荷载-温度路径来描述结构在全过程火灾和荷载作用下的全过程，如图2中Path-2所示。由于试验条件所限，本试验中采用Path-3，试验分两个阶段相继进行，即有考虑初始荷载的升降温火灾试验（O-A-B-C-D-D'）和火灾后剩余承载试验（D'-D-E），该试验考虑了多阶段加载和冷却阶段。火灾后剩余力学性能试验装置如图3所示。
三、试验结果与讨论
火灾试验结果表明：由于混凝土较小的导热系数和热惰性，降温过程中混凝土内部温度仍处于持续上升阶段，温度-时间关系曲线有明显的滞后；混凝土上测点的温度-时间关系曲线在大约120℃时出现明显的温度平台现象(图4所示)。型钢与其包裹混凝土区域形成了一个低温核心区，历史最高温度均低于200℃(图5所示)，这对SRCFST柱构件在经历全过程火灾作用后的力学性能发挥了至关重要的作用。
火灾后剩余力学试验表明：SRCFST柱试件破坏形态与常温下相似，整体表现为失稳产生的弯曲破坏，且外钢管有明显的局部屈曲(如图6)；型钢在火灾后也呈现出明显的侧向挠曲，但翼缘没有明显局部屈曲，表明混凝土的存在一定程度上增强了型钢的稳定性；型钢与其包裹区域的混凝土形成复合约束区，导致内部混凝土强度提高且抑制了裂缝的发展。
SRCFST柱全过程火灾后的荷载-变形曲线可分弹性段、弹塑性段和下降段三个阶段，且下降段比较平缓，构件具有较好的延性(图7)。侧向挠度随着荷载的增加逐渐趋于对称且接近正弦半波曲线，如图8所示。根据量测应变结果，采用弹塑性分析方法和Von Mises准则评估钢管在加载过程中的应力状态，如图9所示，当轴向载荷达到峰值载荷的76%-86%左右时，受压侧钢管首先开始屈服，横向应力在整个阶段保持相对较低的水平发展，并且在受拉侧和受压侧都呈现出受拉状态。
对剩余承载力和延性进行分析(图10)，剩余承载力和延性均随初始火灾荷载比和升温时间比的增加而降低。定义承载力影响系数RSI以评估SRCFST柱经历全过程火灾作用后承载力的损失(图11)，结果表明：对于初始荷载比为0.4的圆形SRCFST柱，其在经历升降温全过程火灾作用后的剩余承载力较常温下的极限承载力高；整体上看，初始火灾荷载比越高的试件其承载力损失越大；方形试件在升降温火灾过程中承载力的损失较圆形试件大，承载力下降10%-20%左右。
四、有限元分析
采用有限元软件ABAQUS建立热力耦合模型，对典型测点的温度变化、荷载-变形关系曲线及剩余承载力进行计算，并将采用图2中三种路径的计算结果与试验结果对比，如图12、图13所示。结果表明：火灾试验后对试件进行卸载，钢管混凝土柱的力学性能有一定程度的恢复；不考虑初始荷载作用计算得到的剩余承载力比path-2/3有显著提高；要准确评估SRCFST柱的火灾后力学性能，不应忽略初始荷载作用。采用现有钢-混凝土组合柱在外荷载和火灾升、降温共同作用后的剩余承载力设计方法，对SRCFST柱的适用性进行评估，基于欧洲规范4第1-1部分中屈曲抵抗的修正设计方法提供了最准确的预测结果。
五、结论
Conclusions
1
火灾后SRCFST柱试件均发生整体失稳破坏，且钢管局部屈曲；混凝土有明显的温度滞后，型钢和包裹区域混凝土形成了一个低温的复合约束区，导致该区域混凝土的强度提高。
2
随升温时间比和初始火灾荷载比的增加，SRCFST柱的剩余承载力和延性均有显著降低；方形试件的承载力在全过程火灾作用后有较大损失，承载力降低10%-20%。
3
初始荷载作用对SRCFST柱构件火灾后的力学性能有不利影响，为准确评估构件或结构火灾后力学性能，应考虑初始荷载的作用。
4
采用现有钢-混凝土组合柱在荷载和温度共同作用后的剩余承载力设计方法，对SRCFST柱的适用性进行评估，结果表明，更高精度的设计方法有待进一步研究和提出。
