摘要:
大跨度双曲屋盖结构形状复杂,目前国内外规范尚未对此类结构的风压系数给出明确规定.为此,本文针对四种典型形状大跨度双曲屋盖,研究其分区风压系数,为工程实践提供有利参考.首先研究分析流场参数、屋盖自身的几何参数等对其表面风压分布的作用,分析得到最不利参数.然后针对各大跨度双曲屋盖的特点,分析并总结出在常用工程高度范围,各典型形状的大跨度双曲屋盖的分区风压系数建议值,并与现行规范中的类似情况比较,为类似结构的实际工程抗风设计提供有益的理论支持和实际参考.
Abstract:
The structure of long-span hyperbolic roofs is complex. At present, domestic and foreign codes have not provided explicit rules for the wind pressure coefficients of such structures. For this reason, this paper focuses on the wind pressure coefficients of four types of long-span hyperbolic roofs and provides a favorable reference for construction practice. Firstly, the effects of flow field parameters and geometric parameters of the roof itself on the surface wind pressure distribution characteristics are analyzed as well, and the most unfavorable parameters are analyzed as well. Then, based on the characteristics of the long-span hyperbolic roofs, the recommended values of the partitioned wind pressure coefficients for the long-span hyperbolic roofs of typical shapes within the common height range were summed up and compared with the similar conditions in the current specifications. And it also provides theoretical support and practical reference for wind resistance design of similar structures.
