硬管母线连接的1000 kV复合外套避雷器和互感器地震模拟振动台试验研究

open access: yesGaoya dianqi, 2022
为研究地震作用下硬管母线连接的特高压复合外套电气设备的地震效应,依据特高压电气设备抗震试验方法进行了硬管母线连接的1 000 kV复合外套避雷器和互感器组成的互连结构体系的地震模拟振动台试验。通过白噪声扫频及标准时程波地震试验,测定了设备的自振频率以及关键部位的应变、加速度响应。试验结果表明:互连结构体系沿管母轴线方向的耦合效应强于垂直管母轴线方向;输入目标峰值加速度越大,互连结构体系的非线性特性越明显;沿管母轴线方向的地震波激励引起的扭转振动中互感器设备的地震响应较为显著 ...

Recovering the status quo: tipping points and earthquake aftermaths in colonial India

open access: yesDisasters, Volume 48, Issue 1, January 2024.
Scholars of disaster politics debate how far natural hazards cause or catalyse political change. This paper builds on recent scholarship on tipping points and social contracts to argue that two case studies of historical earthquakes in 1930s British‐colonised India invite a focus on the dynamics of cooperation and conflict between state and non‐state ...

Study On Structure Mechanics Analysis Of High - rise Isolated Buildings In Moderate Earthquake Intensity And High Wind Pressure Area [PDF]

open access: yes, 2017
隔震建筑经历了实际地震的考验,表现出了优良的减震性能;目前,人们对于高层隔震建筑的减震原理并未清晰,高层隔震建筑也存在结构倾覆稳定的问题,隔震技术并未广泛的应用于高层建筑中。高层隔震建筑在减震与抗风方面对隔震层刚度的要求存在矛盾之处,结构减震效应与风控的均衡,尤其是中烈度高风压地区,是个很有研究价值的课题。 本文对高层隔震建筑隔震层的设计展开了详细的介绍,输入三维地震波,验算了本文研究案例隔震层设计的可行性。从模态分析与反应谱分析的角度,研究了高层隔震建筑的减震原理;分析了高层隔震建筑在设防烈度为7度 ...

地震动脉冲与扭转分量作用下钢框架结构动力响应分析

open access: yesDizhen xuebao
为研究速度脉冲地震动在平动分量与扭转分量联合作用下对钢框架结构的不利影响,本文选取向前方向性效应脉冲地震动、滑冲效应脉冲地震动以及无脉冲地震动作为初始平动记录,通过频域法生成相应的扭转分量。随后,将不同类型的脉冲地震动与扭转分量组合,对按照我国建筑抗震设计规范设计的五层钢框架结构进行了罕遇水平地震下的动力响应分析。结果表明:相较无脉冲的平动地震动,在仅考虑速度脉冲地震动时,向前方向性效应脉冲地震动对结构层间位移角的影响最大,增幅达44%;仅考虑扭转分量时,角柱的层间位移角增大24%,而中柱几乎无变化 ...
