Robustness Design of Roofs in Small and Medium Span Steel Structure

Institute of High Performance Structures, Zhejiang University, Hangzhou 310058, China

摘要: 为防止不明原因导致建筑物严重倒塌,欧州建筑法规给出了一些最低设计要求。首先介绍欧洲标准EN1991-1-7的规定,根据破坏后果对建筑物进行分类以及对各类建筑应采取的构造措施和最低拉结承载力要求。结合欧洲标准和T/CECS 392—2021《建筑结构抗倒塌设计标准》,为保证中小跨度钢结构屋盖的鲁棒性,对其支座设计提出了承载力要求,对屋盖本身提出了承载力及构造建议。

Abstract: To prohibit severe consequence of the building from an unspecified cause, some building codes included some minimum requirements. Eurocode 1991-1-7 is first introduced briefly. Classification of buildings based on failure consequences is presented and required design strategies for each class of buildings and minimum tying capacity are given. Based on this Euronorm and domestic CECS standard, proposals are presented for the supports of steel roofs for the robustness of roofs in small and medium span steel structure, requirements of bearing capacity and construction are also presented for the steel roof themselves.
