This paper employed the ABAQUS finite element (FE) software to conduct a three-dimensional shell-solid FE analysis on the fire resistance of steel-concrete composite continuous beams. Based on validation of the FE model, the effects of load ratio, load position ratio, shear connection ratio, and fire protection layer thickness of steel beams on the fire resistance of continuous beams were subsequently investigated. Additionally, the relations between the variation of internal forces and the deformation stages of composite continuous beams under fire were elucidated. It further revealed the mechanical response mechanisms, including the interface slip behavior, the formation of plastic hinges, and the failure modes. Based on these findings, a differentiated fire protection design strategy of “reinforcing the side spans while simplifying the mid-span” was proposed. The analysis results revealed that: 1) The mid-span of the three-span continuous beam underwent four deformation stages: elastic, elastoplastic, plastic, and catenary action. The catenary effect reduced the required thickness of the fire protection layer. As the restraint stiffness decreased, particularly in the edge span of the continuous beam, the failure mode of the beam shifted from overall lateral instability to failure due to insufficient bearing capacity. In such cases, the fire resistance was equivalent to that of a simply-supported beam due to the absence of the catenary effect. 2) Due to the thermal expansion of the composite beam being constrained by the intermediate supports, a large negative bending moment was generated. Consequently, the plastic hinge at the supports formed earlier than that at the mid-span. Additionally, the positive bending moment at the mid-span of the composite continuous beam decreased or even reversed to negative in the early stages of the fire. Throughout the fire exposure, the continuous beam underwent a significant redistribution of internal forces. 3) The fire resistance of the composite continuous beam was almost unaffected by the shear connection degree η. However, when the steel beam had no fire protection, the end slip decreased significantly with increases in η. As the thickness of the fire protection layer increased, the influence of η on the beam-end displacement weakened, and the end slip was markedly reduced. 4) For composite beams with a load ratio of 0.4, a differentiated fire protection strategy was adopted, which was characterized as “reinforcing the side spans while simplifying the mid-span”. Specifically, the fire protection thickness for the side spans was determined in accordance with the calculation method for simply-supported beams stipulated in the GB 51249—2017 Code for Fire Safety of Steel Structures in Buildings. For the mid-span, fire protection could be omitted entirely, or a minimal layer could be applied to mitigate early-stage deflection during a fire.

应用ABAQUS有限元软件对钢-混凝土组合连续梁的抗火性能进行了三维壳-实体有限元分析,在试验验证的基础上探讨荷载比、荷载位置比、剪力连接度和钢梁防火保护层厚度等参数对连续梁抗火性能的影响,阐明火灾下组合连续梁内力变化规律与其变形阶段之间的联系,揭示火灾下组合连续梁的界面滑移规律、塑性铰形成规律和破坏模式等力学响应机理,提出“边跨加强、中跨简化”的差异化防火保护层设计建议。分析结果表明:1)三跨连续梁的中跨,其变形经历弹性、弹塑性、塑性及悬链线效应四个阶段,悬链线效应使得其所需的防火保护层厚度减少;随着约束刚度的减小(如连续梁的边跨),梁的失效模式由整体侧向失稳转为承载力不足而失效,此时因无悬链线效应,其抗火性能相当于简支梁。2)组合梁升温膨胀受到多余支座的约束,产生较大的负弯矩,其支座处塑性铰形成的时间早于跨中。此外,组合连续梁跨中截面正弯矩值在受火初期减小甚至可能转变为负弯矩。受火过程中,连续梁产生了剧烈的内力重分布。3)组合连续梁的耐火极限几乎不受剪力连接度η的影响,钢梁无防火保护层时,连续梁梁端滑移值随着η的增加而显著减小;随着防火保护层厚度的增加,剪力连接度η对梁端滑移的影响减弱,且梁端滑移值显著减小。4)针对工程中常见荷载比0.4的组合梁,可采用“边跨加强、中跨简化”的差异化防火保护层设计,即边跨防火保护层厚度按GB 51249—2017《建筑钢结构防火技术规范》中简支梁计算,中跨可不进行防火保护或为减小受火初期的挠度略微进行防火保护。
