混合梁斜拉桥开口格室结合部承载性能试验研究

为明确开口格室混合梁钢混结合部的承载性能，基于在建广湛高铁东平水道混合梁斜拉桥结合部构造，设计两个开口格室结合部局部缩尺试件，开展了轴压承载力试验。分析了开口格室结合部的破坏模态、钢底板与混凝土之间的相对滑移、应变分布，对比了钢底板分别采用焊钉和槽口型开孔板连接件对承载性能的影响。结果表明：两试件的承载力约为实桥设计荷载的6.8倍。钢底板上采用焊钉的试件的承载力比采用槽口型开孔板的高约6%，两试件的破坏模态均为混凝土受压破坏，剪力连接件均未被剪断，连接件类型对结合部的承载力和破坏模态影响不显著 ...

确定火灾下轴心受压约束钢构件临界温度的实用计算方法

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 ...
