Jianzhu Gangjiegou JinzhanU形钢板阻尼器具有耗能能力良好、能够依靠自身变形耗能，以及性能稳定、制作方便、价格低廉等优点，但是也存在初始刚度小和承载能力低的问题。为此，提出一种具有T形截面的U形金属屈服阻尼器（简称阻尼器）。基于虚功原理和卡斯蒂利亚诺第二定理，建立了阻尼器的屈服承载力和初始刚度理论公式。基于非线性混合强化本构模型和三维延性断裂准则，建立了考虑材料延性断裂的阻尼器有限元模型。重点考察了阻尼器的刚度、屈服承载力、耗能能力和破坏模式等。通过参数分析量化了几何尺寸等参数对阻尼器力学性能的影响。研究表明，阻尼器在刚度 ...

Jianzhu Gangjiegou Jinzhan为研究距厚比对装配式钢-混凝土组合管（SCCT）剪力墙轴压性能影响，本文设计了6个剪力墙试件的轴压性能试验，分析了试件的破坏形态、应变发展、承载能力和位移延性；基于试验并考虑钢板的初始缺陷，建立SCCT剪力墙的精细化有限元模型，并以距厚比为关键参数进行数值分析。结果表明：钢板厚度相同时，随着距厚比的增大，试件钢板屈曲程度加剧，轴压承载力和刚度减小，位移延性略有提高；基于距厚比与钢板厚度、材料强度的正交分析，建议SCCT剪力墙的距厚比取值不超过80；当含钢率相同时 ...
