一、研究背景

自世贸大厦遭受飞机撞击发生连续性倒塌以来,直至今日建筑结构倒塌事故仍频繁发生,如2021年佛罗里达州12层公寓倒塌和2021年苏州酒店大楼倒塌等(1),均造成了严重人员伤亡和经济损失。建筑结构抗连续倒塌性能是备受专家学者关注的议题之一。目前普遍采用DoD建议的备用荷载路径法对结构的抗连续倒塌性能进行结构分析。近年来,由于试验场地的改进,一些缩尺空间框架的倒塌试验研究得以实现。但空间框架的抗连续倒塌性能是较复杂的,许多问题不易在试验中得到充分验证。

团队提出过一种高效且精确的简化多尺度有限元模拟方法,并对钢管混凝土柱-组合梁平面框架的抗倒塌性能进行了系统研究(详见:简化多尺度模型在组合框架连续倒塌研究中的应用。然而,真实的框架结构中柱--板空间体系抵抗倒塌的传力机制更为复杂。有必要利用简化多尺度模拟方法对钢管混凝土空间框架的抗连续倒塌性能进行进一步研究。基于此,本文选取底层2×1跨钢管混凝土柱-钢梁-RC楼板子结构作为研究对象,分别进行角柱失效、次角柱失效、边柱失效工况的抗连续倒塌有限元分析,对比不同工况下空间框架的破坏模式、均布荷载-竖向位移曲线、梁柱约束反力及抗力模式,并分析边界约束、加载方式、层数、楼板、剪力墙、钢支撑等参数对空间框架抗连续倒塌性能的影响。


二、空间框架简化多尺度建模方法

以某3层公共建筑为原型结构(主体结构为钢管混凝土柱-钢梁-RC楼板框架,选取底层2×1跨空间子结构作为本文的研究对象,分别考虑其在角柱失效、次角柱失效、边柱失效工况下的抗连续倒塌性能。

如图3所示,采用简化多尺度建模方法建立空间框架模型。模型中,梁-柱节点区域组件采用C3D8R实体单元建模,其中非精细区和精细区的网格尺寸分别为40 mm20 mm。而非梁-柱节点区域的梁和柱采用B31梁单元建模,其网格尺寸为100 mmRC楼板采取S4R壳单元,双层钢筋网采用“rebar layer”功能实现。此外,对梁端支座的边界条件进行简化,在梁端建立运动耦合点,并在耦合点水平方向外100 mm处建立固定参考点,采用线性连接单元“Axial+Align”将两点相连,水平约束弹簧的刚度由该方向钢管混凝土柱的总抗侧刚度决定,最终实现对梁端支座的水平边界约束条件的简化。


三、空间框架的抗连续倒塌性能对比

45分别给出了三种工况下空间框架的楼板破坏模式和钢构件破坏模式。可见,柱失效工况下均布荷载作用的失效跨楼板产生拉膜效应,楼板延斜对角方向形成正塑性铰线,沿负弯矩区钢梁方向形成负塑性铰线。角柱失效工况下长跨梁和短跨梁的负弯矩区上翼缘焊缝均发生断裂,且剪切板分别出现局部屈曲和拉剪断裂。次角柱失效和边柱失效工况下短跨梁的负弯矩区上翼缘焊缝和剪切板发生断裂,而单侧长跨梁的负弯矩区上翼缘焊缝和正弯矩区下翼缘焊缝均发生受拉断裂,且剪切板螺栓孔出现挤出破坏。

6给出了不同工况下空间框架的均布荷载-竖向位移曲线对比。不难发现,角柱失效工况的初始刚度和峰值均布荷载较次角柱失效和边柱失效工况降低10~20%。由于边跨约束的增强,边柱失效工况的初始刚度较次角柱失效工况提升了5.1%,但强约束造成了节点的过早断裂,使前者的峰值均布荷载较后者降低了6.6%

基于如图7所示的计算简图,可获得与失效柱相连的梁的抗弯机制和悬链线机制贡献的竖向抗力。可发现,空间框架主要依靠抗弯机制、悬链线机制和楼板机制抵抗连续倒塌。加载初始,空间框架主要依靠抗弯机制和楼板机制抵抗均布荷载,占比约为75%25%。随着竖向位移的增大,悬链机制提供的抗力持续增大,当达到峰值均布荷载时,抗弯机制、悬链线机制、楼板机制贡献的竖向抗力分别达到46.2~61.0%14.2~23.7%23.6~30.3%


四、不同参数的影响

1.边界约束的影响

对比和分析四种边界约束,包括:考虑真实边界约束(前文给出的简化方法)、梁端完全固定、梁端铰接以及无边界约束。图8展示了部分计算结果,结论如下:梁端完全固定和铰接的边界条件将高估悬链线效应所贡献的竖向抗力,而无边界约束将低估空间框架的曲线初始刚度和竖向承载力并高估其变形能力。

2.加载方式的影响

对于空间框架的抗连续倒塌研究,大多数研究均采用楼板均布荷载进行加载,但也有部分研究的加载方式为仅在失效柱的柱顶施加竖向荷载。图910分别给出两种加载方式下总竖向反力-竖向位移曲线和柱顶集中荷载下楼板的破坏模式。综合来看,两种加载方式下空间框架的荷载-位移曲线和整体变形呈现明显差异。由于荷载很难传递至楼板以及周边完好的梁和柱,采用失效柱竖向荷载的加载方式严重低估了空间框架的抗连续倒塌能力。

3.层数的影响

如图10所示,层数的增加提升了曲线初始刚度,但对加载后期的承载力和变形能力影响不大。此外,多层空间框架在角柱失效工况和次角柱失效(边柱失效)工况下分别呈现悬臂深梁效应简支深梁效应

4.楼板的影响

如图11所示,不考虑楼板的空间框架在三种工况下的曲线初始刚度和竖向反力峰值分别降低18.9~35.2%26.8~36.7%

5.剪力墙和支撑的影响

实际结构中往往存在剪力墙和钢支撑等构件,为探究其影响,分别建立考虑钢板剪力墙和X型钢支撑的空间框架模型,如图12所示。图13展示了钢板剪力墙和X型钢支撑对均布荷载-竖向位移曲线的影响。不难看出,钢板剪力墙和X型钢支撑对空间框架的初始刚度和承载力均有提升,其中X型钢支撑对初始刚度的提升效果更明显,但二者对空间框架在连续倒塌工况下的变形能力有所削弱。


五、结论

Conclusions

1






角柱失效工况的初始刚度和峰值均布荷载较次角柱失效和边柱失效工况降低10~20%。由于边跨约束的增强,边柱失效工况的初始刚度较次角柱失效工况提升了5.1%,但强约束造成了节点的过早断裂,使前者的峰值均布荷载较后者降低了6.6%

2






加载初始,空间框架主要依靠抗弯机制和楼板机制抵抗均布荷载,占比约为75%25%。当达到峰值均布荷载时,抗弯机制、悬链线机制、楼板机制贡献的竖向抗力分别达到46.2~61.0%14.2~23.7%23.6~30.3%

3






梁端完全固定和铰接的边界条件将高估悬链线效应所贡献的竖向抗力,而无边界约束将低估曲线初始刚度和竖向承载力。由于荷载很难传递至楼板以及周边完好的梁和柱,采用失效柱竖向荷载的加载方式严重低估了空间框架的抗连续倒塌能力。层数的增加提升了曲线初始刚度。

4






不考虑楼板时曲线初始刚度和竖向抗力峰值分别降低18.9~35.2%26.8~36.7%。钢板剪力墙和X型钢支撑对初始刚度和承载力均有提升,但二者对空间框架的变形能力有所削弱。
