钢结构螺旋楼梯结构的直接分析法研究

钢结构螺旋楼梯因其特殊的异形结构受力复杂，使得传统线性分析法不能准确预测其力学响应进行稳定性设计，尤其是在确定计算长度时。研究采用直接分析法来克服这些限制，考虑了结构整体性和构件的初始缺陷，为分析和设计这类结构提供了一个高效且安全的方法。以一个具体工程为例，使用NIDA软件进行了直接分析法的稳定性研究，并将所得结果与线性分析法的结果进行了对比。研究考察了在全跨满载、左半侧满载、右半侧满载以及不同扇形组合活荷载分布下的力学响应，以及不同支座条件对楼梯结构响应的影响。结果表明 ...

Research on the load-bearing capacity and defect sensitivity of three-dimensional lattice cylindrical shells under axial compression

世界航天已经进入了大规模深空探测的新时代，对承载人类驶向星辰大海梦想的重型运载火箭，在干质比、可靠性和轻量化设计方面提出了更高的要求。为此，迫切需要发展更为高效和可靠的全新结构设计理念，促进超大尺寸重型运载火箭结构设计的重大变革。三维点阵夹层壳因其抗弯刚度高、轻量化空间大和多功能性一体化等优势，是应用于重型运载火箭壳体的一种潜在的结构形式。然而，当前制约其工程应用主要有三个方面：第一，三维点阵夹层壳体结构制备工艺不成熟，特别是制备空间的约束导致难以一体化成型大尺寸试样 ...
