Jianzhu Gangjiegou Jinzhan五边形三四撑杆全铰接弦支网壳区别于多撑杆索穹顶结构，是将索穹顶结构上层脊索转换为脊杆，形成一种由预应力索、杆组合而成的全铰接曲面双层网格结构体系，便于铺设刚性屋面，减少造价。与传统网壳结构相比，该结构具有良好稳定性和施工便宜性的特点。该结构下弦节点设置三根或四根撑杆，有效提高了整体结构的侧向刚度和稳定性，同时采取铰接节点形式连接，简化节点构造，便于张拉施工。针对五边形三四撑杆全铰接弦支网壳结构，建立ANSYS有限元模型，分析在不同组合工况下该结构索杆内力变化与位移规律。同时 ...

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 ...
