T形PEC柱抗震性能的数值模拟分析

利用ABAQUS软件对14个T形PEC柱进行低周反复加载模拟，分析不同参数对T形PEC柱抗震性能的影响规律。结果表明：T形PEC柱的滞回曲线呈饱满的平行四边形，且刚度退化稳定，耗能能力和延性良好；提高混凝土强度等级虽然可增大柱的初始刚度，但混凝土强度等级过高则会导致柱的延性降低，刚度退化加剧，抗震性能降低；在T形PEC柱内设置横向拉杆，且将x方向和z方向的横向拉杆相互焊接，有利于对混凝土形成套箍作用从而提高柱的抗震性能，但拉杆间距不宜大于150 mm ...

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 ...
