请注意-物品可能需要大约4周的时间才能送达。本规范涉及按照以下要求设计的钢结构工程: 符合:BS 5950-1《建筑钢结构使用:设计实施规范:轧制和焊接型材》欧洲规范3:第1.1部分《建筑通用规则和规则》，其中（DD ENV1993-1.1）在国家应用中引用了BS 5950 文件也被考虑在内。它可以用于所有类型的建筑结构设计的静态 加载。它不用于动态加载的钢结构 除非进行适当的修改，否则结构或疲劳是一个因素。 规范描述了项目中要包含的信息 规范，还包括材料、图纸准备、制造、， 安装和防护处理要求，包括标准 油漆涂层。钢结构承包商和 雇用者其他要求分配给工程师，但工程师可能不会 直接成为钢结构合同的一方，但可由 业主或钢结构承包商。还应注意的是 某些设计-建造合同分担设计责任，并在这些合同中 例如，工程师的角色必须重新定义。本规范应通过以下方式引入钢结构合同: 项目规范，其内容在本文中描述。项目 规范还应包括可能需要的任何添加或修改 业主要求符合国家钢结构规范 当合同的形式、行为或其他方面 结构是非正统的。

Please note - item may take approximately 4 weeks for delivery.This specification deals with structural steelwork designed in accordance with:BS 5950-1 'Structural use of steelwork in buildings:Code of practice for design: rolled and welded sections' Eurocode 3: Part 1.1 'General rules and rules for buildings' where the (DD ENV1993-1.1) references to BS 5950 in the National Application Document are taken into account.It can be used for all types of building construction designed for static loading. It is not intended to be used for steelwork in dynamically loaded structures or where fatigue is a factor unless appropriate amendments are made. The Specification describes the information to be included in a Project Specification, and also covers materials, preparation of drawings, fabrication, erection and the requirements for protective treatment including standard paint coatings.Specific requirements are placed on the Steelwork Contractor and the Employer. Other requirements are allocated to the Engineer, who may not be directly a party to the steelwork contract, but may be engaged by the Employer or by the Steelwork Contractor. It should also be noted that in certain design-build contracts design responsibility is shared and in these instances the role of Engineer will have to be redefined.This Specification should be introduced into a steelwork contract by a Project Specification, the contents of which are described herein. The Project Specification should also include any additions or modifications that may be required to the National Structural Steelwork Specification by the Employer for a particular contract when the form behaviour or other aspects of the structure are unorthodox.
