考虑机械载荷的移动幕帘载荷计算方法研究
|
摘要
移动幕帘是运行于现代开合式建筑之上的新型建筑机械结构。移动幕帘的载荷计算,需要综合考虑建筑结构原有载荷和幕帘机械运动引起的机械载荷。建筑结构设计规范中机械载荷的计算方法说明有欠缺,而机械设计规范中虽然有相关计算方法,但却没有给出直接应用于建筑结构设计中的办法。基于两类设计规范,提出了将机械设计规范中机械载荷的计算方法应用于建筑结构计算中的方法,并应用于实际移动幕帘的结构设计计算中。综合建筑和机械的设计规范,可为今后同类结构的载荷分析组合和结构计算提供参考。
The movable curtain is a new type of structure that runs on modern retractable architectures.When designing this structure,both structural loads and mechanical loads,which stems from mechanical movements of the curtains,should be considered.But mechanical loads are not defined in the design rules for architecture structures.The design rules for machines do have some specifications for mechanical loads,but have never been applied to the design of architecture structures.Based on these two design rules,this paper presents a methodology of applying design rules for machines to the design of movable curtain.Then the proposed method is tested in the design of the movable curtain.Such an approach is a novel integration of design experiences from both architecture and mechanics,which can serve as a practical guide to future design of similar structures.
