某异形空间曲面耐候钢砖幕墙结构体系设计

Design of a weathering steel brick curtain wall structure system with special⁃shaped space curved surface

不同族的正(余)弦函数曲线沿高度和长度方向共同放样,可形成复杂的空间曲面。将0°、45°、90°和135°放置的耐候钢砖沿异形空间曲面进行模块化排布,可形成复杂的耐候钢砖幕墙。针对此耐候钢砖幕墙,提出了由内置异形钢框架、面外支撑和空心钢砖所组成的稳定幕墙体系,并对此幕墙体系的力学性能进行了精细化的有限元模拟分析。分析结果表明,该幕墙体系整体受力性能好,结构传力途径明确,可满足结构承载和正常使用要求,是一种能满足建筑的空间视觉与美观要求的幕墙结构体系。

The sine(cosine)curves of different families can be lofted together along the height and length directions to form a complex space curved surface.Weathering steel bricks placed at 0°,45°,90°and 135°are modularized along the special-shaped space curved surface to form a complex weathering steel brick curtain wall.A stable curtain wall system consisting of a built-in special-shaped steel frame,out-of-plane supports and hollow steel bricks was proposed for this weathering steel brick curtain wall,and the mechanical properties of this curtain wall system were simulated and analyzed by refined finite element method.The analysis results show that the overall stress performance of the curtain wall system is good,and the structural force transmission path is clear,which can meet the requirements of structural bearing and normal use.It is a curtain wall structure system that can meet the requirements of space vision and aesthetics of buildings.
