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 ...

模块化轻钢-混凝土夹心复合楼板力学性能研究

Jianzhu Gangjiegou Jinzhan
模块化轻钢-混凝土夹心复合楼板是一种新型的装配式结构形式，具有装配率高、预制率高、连接方便、自重轻等特点，为研究该复合楼板的抗弯承载力和连接节点的力学性能，对其进行了试验研究及有限元分析。通过试验发现模块化轻钢-混凝土夹心复合楼板具有良好的变形能力且试件最终的破坏特征为弯曲破坏；当加载至极限荷载时，复合楼板和钢梁连接良好，连接节点未出现明显塑性变形。之后在试验的基础上，建立了精细化有限元模型，进行了参数分析。结果表明，纵筋配筋率从0.45%提升至1.39%时，复合楼板的极限抗弯承载力提高了108.22%，
