L形钢管柱灌浆套管连接弯剪性能研究

Jianzhu Gangjiegou Jinzhan
文中提出了一种适用于模块装配式钢结构建筑梁柱节点的L形柱灌浆套管连接形式，并对该连接的抗弯剪性能展开了研究。设计并制作了6个L形柱灌浆套管连接试件，对其分别开展了三点和四点抗弯试验研究，随后还进行了有限元参数分析，主要研究了不同内套管长度下该连接的弯剪承载力与纯弯曲承载力特性。试验结果表明：在试验所验证的内套管长度范围内，增加内套管长度可显著提升连接的弯剪、纯弯曲承载力及延性；同尺寸灌浆连接的弯剪承载力和纯弯曲承载力基本一致。有限元分析结果表明：当内套管长度超过一定范围后 ...

混合梁斜拉桥开口格室结合部承载性能试验研究

Jianzhu Gangjiegou Jinzhan
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 ...
