Jianzhu Gangjiegou Jinzhan, 2022 提出一种钢管混凝土柱-横肋波纹钢板剪力墙，其中横肋波纹钢板作为主要抗剪单元以其较大的面外刚度和良好的抗整体屈曲性能有效延缓了面外失稳的发生，并提供了稳定的抗侧承载力。多根钢管混凝土柱与波纹钢板组合形成的异形剪力墙可适应住宅钢结构中的墙体转角造型，且能够有效提高剪力墙的面外稳定性能。在结构应用设计时，需提出该新型体系的合适简化分析模型。根据横肋波纹钢板剪力墙的构造组成和力学特性，提出采用正交异性板单元的简化模拟方法，在MIDAS软件中建立典型异形剪力墙的简化模型并与ABAQUS模型进行对比 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) with white‐light emission have significant potential in solid‐state lighting and display due to the designable structure and excellent luminescent properties. However, OIHPs are prone to damage during bending due to the brittleness of crystals, which limits their application in the field of flexible

Jianzhu Gangjiegou Jinzhan, 2005 打黑渡怒江大桥拱架为钢结构,采用万能杆件拼装而成,形成空间桁架。由于拱架是整个拱桥拱肋施工的直接支撑结构,所以拱架本身的强度和稳定性就显得特别重要。针对拱桥施工中的这一关键技术问题,本文对该桥拱架整体及在整个拼装过程中各阶段的强度和稳定性进行了分析,同时也计算了相应的拱桥拱肋的强度及稳定性和拱架应设置的最终预拱度。根据计算结果,对整个施工过程提出了重要的有价值的改进意见。
