Jianzhu Gangjiegou Jinzhan, 2023 为研究部分包裹钢-混凝土组合轴压柱的整体稳定性能与设计方法，完成了两个试件的试验。利用有限元软件ABAQUS建立部分包裹钢-混凝土组合柱数值分析模型，并对比试验数据校核模型准确性。利用该数值模型进行参数分析，考虑材料强度、组合柱长细比、含钢率、纵筋和系杆的布置对该类轴压构件整体稳定性能的影响，分别获得不同因素影响下构件绕强轴和绕弱轴的极限承载力。结果表明，材料强度、系杆间距及含钢率对稳定性能的影响均较为显著，纵筋对轴压稳定性能的影响可以忽略。基于数值模拟结果，按照不同含钢率进行归类分析 ...

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

Rare Metals, EarlyView.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...
