模块化钢框架模块间全螺栓拼接节点力学性能分析

Jianzhu Gangjiegou Jinzhan
文中提出了一种新的模块化钢框架模块间全螺栓拼接方法，通过模块间连接键、单向螺栓与对穿螺栓的协同作用实现了模块间全螺栓装配。为研究该拼接节点的力学性能，采用ABAQUS有限元软件建立了模块化钢框架模块间全螺栓拼接节点精细化数值模型，并对其进行了低周往复加载数值模拟，分析了该节点的滞回曲线、骨架曲线、延性、耗能及承载力性能；还建立了节点初始转动刚度计算模型，推导了节点初始转动刚度计算公式，并与数值模拟计算结果进行了对比验证，验证了初始转动刚度计算公式的准确性。结果表明：该全螺栓拼接节点的构造设计合理 ...
