铰接方钢管组合异形柱框架抗震性能研究

Jianzhu Gangjiegou Jinzhan
为解决村镇住宅体系存在的装配式程度及标准化程度较低、现场焊接工作繁多、室内建筑面积浪费等问题，提出了一种铰接方钢管组合异形柱框架体系。该体系中异形柱采用3根空钢管通过钢板与加劲肋组合而成的L形柱，梁柱节点为腹板螺栓连接的铰接节点。通过拟静力试验对该体系的抗震性能进行研究。研究结果表明：相比于铰接钢管混凝土组合异形柱，铰接空钢管组合异形柱框架体系先于梁端出现转角，最后破坏模式为柱脚破坏，具有更优良的抗震耗能和更缓慢的强度与刚度退化，并通过对比刚接节点和铰接节点的骨架曲线 ...

带水平加劲肋PEC墙-钢梁刚接节点极限承载力

Jianzhu Gangjiegou Jinzhan
部分包覆钢-混凝土组合（Partially encased composite，PEC）墙在装配式建筑领域具有广阔的应用前景，但其节点承载力尚待进一步深入研究。对带水平加劲肋PEC墙-钢梁刚接节点受力性能进行研究，基于既有试验验证有限元模拟的准确性，考察水平加劲肋厚度、柱间腹板厚度、暗柱截面高度和暗柱横隔板间距等参数对节点承载力的影响，根据节点受力机理和有限元分析结果，提出带水平加劲肋PEC墙-钢梁刚接节点极限承载力计算式。研究表明，计算值与有限元结果吻合良好，适用于带水平加劲肋PEC墙 ...

单边螺栓T型钢连接梁柱节点地震损伤性能评估

Jianzhu Gangjiegou Jinzhan
随着装配式钢结构在建筑工程领域的应用日益广泛，单边螺栓连接作为一种高效、便捷的连接方式，逐渐受到业界的青睐。H型钢梁、方钢管柱通过T型钢连接件和单边螺栓连接技术形成新型装配式钢框架结构，梁柱节点作为整个框架体系的核心，其抗震性能对整体结构的影响至关重要。为评估单边螺栓T型钢连接梁柱节点在地震过程中的损伤情况，开展了4种不同刚度单边螺栓T型钢连接梁柱节点的拟静力试验。通过试验，获得了单边螺栓T型钢连接梁柱节点的破坏模式、滞回性能和初始转动刚度，分析了不同刚度的T型钢连接件对梁柱节点的破坏模式 ...
