钢框架-自复位SRC墙板结构的地震易损性分析

Jianzhu Gangjiegou Jinzhan
为了研究钢框架-型钢混凝土（SRC）自复位墙板结构的抗震性能，完成了钢框架-自复位SRC墙板子结构模型的低周往复加载试验，以研究其工作机理和失效机制。提出了基于宏观单元的非线性分析模型，并利用试验结果验证模型的准确性，研究结果表明该非线性分析模型能较好地模拟自复位SRC墙板的非线性行为。分别建立6层和15层钢框架-自复位SRC墙板结构的整体模型并进行增量动力时程分析（IDA）。以地面峰值加速度为地震动强度指标，以最大层间位移角为损伤指标，根据IDA结果得到不同极限状态下的易损性曲线，建立地震易损性矩阵 ...

SF₆气体压力对GIS隔离开关操作时暂态电压过程的影响分析

Gaoya dianqi
SF6气体压力直接关系到气体绝缘组合电器（GIS）隔离开关分合过程中触头间的动态绝缘特性。为研究SF6气体压力变化对隔离开关操作时所激发暂态电压过程的影响，文中根据GIS隔离开关开合短母线方式1试验，基于1 100 kV GIS隔离开关搭建试验平台，将隔离开关绝缘气体压力从0.4 MPa分别提升至0.5 MPa和0.54 MPa，利用超宽频电压监测系统准确测量了隔离开关操作时断口两侧的暂态电压，并分析暂态电压时域特征、频谱分布和时频分布特征变化。通过试验数据分析发现当随着SF6气体压力增大 ...
