确定火灾下轴心受压约束钢构件临界温度的实用方法

Jianzhu Gangjiegou Jinzhan
火灾下轴心受压约束钢构件的力学响应复杂，所产生的温度内力导致其承载失效的确定与计算难度大。为简化基于结构构件高温承载极限状态的约束钢构件抗火设计方法，采用有限元数值模拟方法开展了大规模参数分析，以确定火灾高温下轴心受压约束钢构件的承载与失效规律。基于试验验证的可靠有限元模型，研究了不同长细比、轴向约束刚度比和初始荷载比等参数对轴心受压约束钢构件火灾响应的影响。结果表明，上述参数均将显著影响约束钢构件的火灾响应，且当长细比较大、轴向约束刚度比较小、初始荷载比较大时 ...

方GFRP-橡胶混凝土-钢双管组合长柱轴压性能研究

Jianzhu Gangjiegou Jinzhan
为研究GFRP-橡胶混凝土-钢双管组合柱（GFRP-rubber concrete-steel double-skin tubular columns，RC-DSTCs）的轴压性能，对7个长柱试件进行了轴压试验。观察RC-DSTCs在轴压状态下的破坏模式，基于荷载-位移曲线、荷载-应变曲线和环向-轴向应变曲线分析了长细比、空心率对RC-DSTCs轴压性能的影响，提出了RC-DSTCs的轴压理论承载力计算式。结果表明：随着长细比的提高，RC-DSTCs的轴压破坏模式由材料破坏向弯曲失稳破坏转化，但所有RC-
