管肋开孔双钢板剪力墙滞回性能研究

Jianzhu Gangjiegou Jinzhan
为改善钢板剪力墙滞回性能，使其具备稳定耗能能力，提出了一种管肋开孔双钢板剪力墙。利用Abaqus有限元软件建立了包括管肋（开孔）双钢板剪力墙在内的7种不同类型钢板剪力墙的有限元数值模型，对其破坏模式、滞回性能、承载力、刚度和耗能能力等方面进行了对比分析。结果表明：在墙体钢板横截面总厚度一定的情况下，管肋双钢板剪力墙具有较高的承载能力和良好的滞回性能；钢管作为板间加劲肋，通过合理布置能够对两侧的墙面板起到较好屈曲约束的效果，面外变形较小，同时减小了由于墙面板预开孔洞造成的承载力、强度和刚度的损失 ...

距厚比对装配式SCCT剪力墙轴压性能影响研究

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 ...
