摘要
装饰条可有效增强幕墙整体结构的美观度并提高遮阳性能,但大规格装饰条的应用会明显改变幕墙立柱的整体承载性能。针对装饰条与立柱组合结构,合理考虑其结构特征、受载与边界条件以及连接方式,基于有限元分析方法,构建了精细化力学分析模型,研究了极限载荷作用下装饰条与立柱组合结构的力学性能,并分析了装饰条不同尺寸、安装角度与连接状态下装饰条对立柱整体力学性能的影响规律。研究结果对装饰条与幕墙立柱组合结构的优化设计具有指导意义和数据支持。
The decorative strip can effectively enhance the beauty of the overall structure of the curtain wall and improve the shading performance, but the application of large-scale decorative strip will significantly change the overall load-carrying performance of the column of curtain wall. Based on the finite element analysis method, a refined mechanical analysis model is constructed for the composite structure that contains column and decorative strip, considering its structural characteristics, load, boundary conditions and connection mode reasonably. The mechanical properties of the composite structure under ultimate load are studied, and the influence analysis to the overall mechanical performance of column is carried out under various sizes of decorative strip, changing installation angle and different connection state between decorative strip and column. The research results have guiding significance and data support for the optimal design of these types of structure.
