为了研究含错层节点钢管混凝土柱⁃钢梁框架结构抗整体性倒塌能力,基于已有试验,采用OpenSees分别建立了不同错层高度钢管混凝土柱⁃钢梁框架结构数值分析模型。对模型进行20条地震动记录下的增量动力分析(IDA),得到结构倒塌阶段的易损性曲线,并利用结构抗倒塌安全储备系数评估结构的抗整体性倒塌能力。结果表明:地震动强度较低时,错层高度对结构的承载力和变形影响不大,增量动力分析曲线差异较小,地震动强度较高时,不同错层框架与普通框架的增量动力分析曲线差异十分显著,第三类错层框架和第一、二类错层框架以及普通框架相比,变形增长更快,后期退化程度更大;普通框架(KJ⁃1)、第一类错层框架(SKJ⁃1)、第二类错层框架(SKJ⁃2)和第三类错层框架(SKJ⁃3)的抗倒塌安全储备系数分别为3.53、2.75、2.2和1.8,SKJ⁃1、 SKJ⁃2和SKJ⁃3相比KJ⁃1抗倒塌安全储备系数分别降低了22.1%、 37.7%和49.0%,说明含错层节点框架结构抗整体性倒塌能力明显低于普通节点框架结构,且随着结构错层高度的增加其性能降低显著。
To investigate the progressive collapse resistance of concrete-filled steel tubular (CFST) column-steel beam frame structures with staggered joints
numerical models
with varying staggered floor heights were developed in OpenSees based on existing experimental data. Incremental dynamic analysis (IDA) was conducted using 20 ground motion records to derive collapse fragility curves
and the structural global collapse resistance was evaluated using the safety reserve factor against collapse. Results indicated that at low ground motion intensities
the staggered joint height had minimal impact on structural bearing capacity and deformation
with slight differences in IDA curves. However
at high intensities
significant differences emerged between staggered frames and ordinary frames. The third type of staggered frame exhibited faster deformation growth and greater late-stage degradation compared to the first and second types as well as the ordinary frame. Collapse Margin Ratio (
CMR
) values for ordinary (KJ-1)
first-type staggered (SKJ-1)
second-type staggered (SKJ-2)
and third-type staggered (SKJ-3) frames were 3.53
2.75
2.2
and 1.8
respectively. SKJ-1
SKJ-2
and SKJ-3 showed 22.1%
37.7%
and 49.0% reductions in
CMR
compared to KJ-1. These findings demonstrate that staggered joint frames have significantly lower global collapse resistance than ordinary frames
with performance decreasing as staggered joint height increases.
