钢框架-灌浆轻钢剪力墙结构抗震性能试验研究

Jianzhu Gangjiegou Jinzhan
对钢框架-灌浆轻钢剪力墙结构足尺试件进行了水平低周往复加载试验，研究了灌浆轻钢剪力墙与钢框架的耦合效应，分析了结构的破坏模式、受力特征和耗能机理，得到了结构的承载能力、抗侧刚度、延性及耗能能力等。通过与纯钢框架及冷弯薄壁型钢灌浆墙体结构的试验结果对比，发现灌浆轻钢剪力墙通过自攻螺钉采用内嵌的方式与钢框架连接，二者具有良好的协同工作性能，框剪结构的抗剪承载力和抗侧刚度分别是钢框与墙体对应值之和的1.50倍和1.64倍，结构延性系数达5.42，抗震性能优良，研究结果可为该类结构的设计研究提供科学基础。

钢塔-组合塔混合结构结合部承载性能试验研究

Jianzhu Gangjiegou Jinzhan
针对新型钢塔-组合塔混合结构结合部构造，开展了局部缩尺模型轴压试验，并建立了非线性有限元模型与试验结果进行比较。研究了钢塔-组合塔结合部的极限承载力以及破坏形式，探究了钢板应变分布规律和焊钉受力分布规律，并对传力路径和荷载分担比例进行了变参数分析。研究结果表明：新型钢塔-组合塔混合结构结合部的承载力符合设计要求；结合部的破坏形式表现为承压板下方钢壁板达到屈服并发生鼓曲变形；承压板为结合部的核心传力构件，增大板厚可以提高结合部承载力以及承压板所传递的荷载，其厚度宜与外壁钢板厚度相近 ...
