一、研究背景
内配型钢钢管混凝土(Steel-reinforced concrete-filled steel tube,SRCFST)是在钢管混凝土(CFST)中配置型钢而形成的新型组合构件,其延性和耐火性能较CFST构件显著提升。在组合构件中,钢-混凝土的粘结性能影响着各部件间的协同作用,其是组合构件发挥优异力学性能的基础。火灾是最普遍、最严重的自然灾害之一,火灾损伤会导致钢-混凝土界面性能发生变化,进而影响组合构件的受力性能,研究组合构件中钢-混凝土之间的粘结性能十分必要,但目前关于火灾后SRCFST构件中型钢-混凝土界面性能的研究尚无报道。为此,本文完成了22个火灾后SRCFST试件的静力推出试验,并建立了型钢-混凝土界面全过程的简化粘结强度-滑移关系模型。
二、试验结果
共设计了22个SRCFST试件进行推出试验,包括4个常温试件及18个火灾后试件。试验参数包括:受火时间(t0:0min、30min、60min及90min);型钢尺寸(h:80mm和160mm);界面长度(L:300mm、450mm和600mm),以及加载方式(单调加载和分级加载)。试验测量内容包括试件的破坏形态、温度-时间曲线、以及全程荷载-滑移(P-S)曲线。试件截面示意如图1,试验分两个阶段,包括火灾试验和静态推出试验,火灾和推出试验装置分别如图2和图3所示。
图1 试件的截面示意及几何尺寸
图2 火灾试验装置
图3 推出试验装置
火灾试验结果表明:火灾作用后钢管表面形成红棕色氧化物,随着受火时间的增加,钢管表面的氧化层发生脱落(如图4)。火灾后试件的混凝土表面出现不同程度的裂缝,裂缝基本沿着靠近钢管的外围区域呈环向分布,其随着受火时间的增加逐渐增多。此外,内部混凝土存在明显的升温滞后,受火30min、60min和90min后,核心混凝土(测点3)经历的最高温度分别约达到253°C、423°C和589°C,钢管表面(测点4)经历的最高温度分别约达到598°C、773°C和959°C(如图5)。
图4 火灾后钢管与混凝土表面的破坏
图5 试件的温度-时间曲线
推出试验结果表明:SRCFST-1类试件在推出过程中混凝土裂缝较SRCFST-2类试件更多,裂缝主要出现在型钢翼缘端部,随着受火时间的增加,推出试验造成的混凝土裂缝数量减少,在试件的自由端,型钢表面有明显的混凝土划痕(如图6和7)。不同于型钢混凝土柱推出试验中混凝土的破坏,得益于外钢管良好的约束作用,所有SRCFST试件的混凝土在推出试验后仅产生细微的裂缝。型钢-混凝土界面处的混凝土表面产生明显划痕,随着受火时间的增加,混凝土划痕逐渐减少,表面裂缝逐渐增多(如图8)。

图7 试件的自由端破坏对比
图8 界面处型钢与混凝土的破坏
从自由端的荷载-滑移(P-S)全过程曲线可见(如图9),对比试件的试验曲线吻合较好,常温下与高温后试件的荷载-滑移曲线形态相似,曲线可分为三个阶段:初始阶段(OA)、粘结破坏阶段(AB)和残余阶段(BC)。分析不同影响参数可见(如图10):随着受火时间的增加,试件的粘结强度呈现出先上升再降低的趋势;随着腹板高度的增加,试件的粘结强度逐渐降低;随着界面长度的增加,特征粘结强度逐渐增大;加载方式对型钢-混凝土界面粘结性能的影响不明显。

图10 不同参数对粘结性能的影响
三、理论模型
通过典型的P-S曲线模型,以升温时间、界面长度以及型钢尺寸为主要参数,分析得到各因素对初始粘结强度、极限粘结强度以及各自对应的滑移值的相互关系,并建立了火灾后SRCFST构件中型钢-混凝土界面的粘结强度-滑移曲线模型,如图11。
图11 P-S and τ-S曲线模型
基于建立的理论模型,采用ABAQUS有限元软件中的非线性弹簧单元和热-力顺序耦合方法建立了火灾后SRCFST柱中型钢-混凝土界面性能分析的数值模型(如图12),并基于该模型分析了火灾后SRCFST试件(SRCFST-1-60a)中型钢-混凝土界面的应力分布和变化规律(如图13和14)。

四、结论
Conclusions
1
与常温下SRCFST构件相比,火灾后构件中型钢-混凝土界面仍表现出良好的粘结性能,试件的荷载-滑移曲线可分为初始阶段、粘结破坏阶段和残余阶段。
2
随着受火时间从30min增加到60min和90min,试件的平均极限粘结强度分别降低48.3%和69.5%;当型钢腹板高度与翼缘板宽度之比从1.0升至2.0时,极限粘结强度降低40%。
3
当界面长度从300mm增加到600mm时,初始和极限粘结强度分别增加136.7%和91.4%;加载方式对型钢-混凝土界面粘结强度的影响不明显。
4
提出了火灾后SRCFST构件中型钢-混凝土界面的全过程粘结强度-滑移模型,建立了火灾后构件中型钢-混凝土界面粘结行为的有限元分析模型,预测与试验结果吻合较好。
