T形PEC柱抗震性能的数值模拟分析

open access: yesJianzhu Gangjiegou Jinzhan
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 ...

特高压换流站气体绝缘金属封闭输电线路(GIL)抗震性能提升方法研究

open access: yesGaoya dianqi
随着气体绝缘金属封闭输电线路(GIL)在特高压换流电站中的广泛应用,地震对其结构安全的影响备受关注。文中基于精细化有限元模型,分析了GIL在地震作用下的响应特征,并针对抗震薄弱点提出了针对性的性能提升方法。研究表明,GIL的主要薄弱点位于竖向转角处,存在外壳强度破坏和内部导体接头拔出破坏两种模式。此外,支架的动力放大效应显著,加速度放大系数通常超过2.0,但支架的动力放大作用并非唯一决定GIL抗震性能的因素。通过提高支架的基频和固定支架与外壳的连接方式,能够有效降低内部导体的相对位移峰值和外壳的应力峰值,
