ISO/TC 167 - Steel and aluminium structures

This document specifies test methods to determine loss of pretension in high-strength bolts due to the presence of coatings on the faying surface(s) of a bolted joint to be used in structural steelwork, when any of the coatings are thick enough to affect the pretension in a bolt in the short term, or can show significant deformation over time under sustained loads (creep-prone materials). The presence within the grip of the bolt of other materials having considerably smaller stiffness than steel, such as insulation, is not included in this test method.

This document specifies a procedure to determine the slip factor of faying surfaces in slip-resistant (friction) connections to be used in structural steelwork. The method is mainly applicable to uncoated and coated components made of steel with various surface treatments. This document applies mainly to carbon steels but can be used for other type of steels as appropriate.

This document defines the general requirements for erection of steels used in the execution of structural steelwork as structures or as manufactured components in conjunction with ISO 17607-1. Additional requirements to be addressed in the execution of structural steelwork, as structures or as fabricated components, can be found in other parts of the ISO 17607 series.

This document defines general requirements for the execution of structural steelwork for: — structural steel buildings; — general structures, designed, fabricated, and erected in a manner similar to buildings with building-like load-resisting elements, e.g. support framing for equipment, tanks, vessels, and pipelines; — crane-supporting structures; — typical roadway and pedestrian bridges including those constructed using rolled sections, welded plate girders, or trusses (lattices). This document applies to structures or fabricated components that are produced from: — hot-rolled and cold-formed structural steel products up to and including a nominal yield strength of 700 MPa with a thickness of 3 mm and above; — hot-finished and cold-formed structural steel hollow sections, up to and including a nominal yield strength of 700 MPa, including standard range and custom-made rolled products and hollow sections manufactured by welding. This document also applies to steel components in composite steel and concrete structures, and in structures combining steel with other materials. This document defines requirements independent of the type and shape of the steel structure, including structures subjected to fatigue or seismic loading. The requirements are expressed in terms of execution levels. This document does not define all requirements for other types of fabricated steel structures (e.g. railway bridges, roadway and pedestrian bridges using welded box sections or arch boxes, cable-supported bridges over 100 m span, moving bridges, monorails, steel towers, masts, chimneys, silos, tanks, pipelines, antennae, offshore platforms). However, this document provides general guidance regarding fabrication and erection practices that may be used together with the appropriate ISO, regional or national design standards for such structures. This document does not cover requirements for the following: — sheeting; — fabrication of stainless steels. This document does not apply to design of steel structures. NOTE Design is inextricably a part of the design-fabrication-erection sequence, including the application of tolerances, and cannot be considered in isolation. This document is intended to be used, as appropriate, together with national standards and other documents, observing the provisions in this document concerning such use.

This document defines the general requirements for the constituent products of steels and steel products used in the execution of structural steelwork as structures or as fabricated components in conjunction with ISO 17607-1. Additional requirements to be addressed in the execution of structural steelwork, as structures or as fabricated components, can be found in other parts of the ISO 17607 series.

This document defines the general requirements for fabrication in the execution of structural steelwork as structures or as fabricated components in conjunction with ISO 17607-1. Additional requirements to be addressed in the execution of structural steelwork, as structures or as fabricated components, can be found in other parts of the ISO 17607 series.

This document defines the general requirements for welding in the execution of structural steelwork as structures or as manufactured components in conjunction with ISO 17607-1. Additional requirements to be addressed in the execution of structural steelwork, as structures or as fabricated components, can be found in other parts of the ISO 17607 series.

This document defines the general requirements for structural bolting in the execution of structural steelwork as structures or as fabricated components, in conjunction with ISO 17607-1. Additional requirements to be addressed in the execution of structural steelwork, as structures or as fabricated components, can be found in other parts of ISO 17607.

Establishes the principles and general rules for the use of steel materials and design of steel structures in buildings. It is also applicable to bridges, civil engineering and related structures, but for such structures it may be necessary to consider other requirements.

This document defines two performance levels for welded joints, namely Basic Demand and Critical Demand, for longitudinal tensile strength of weld metals, impact toughness of weld metals, and heat affected zones (HAZ) to suit the level of seismic performance required of welded steel structures. This document supplements provisions of applicable standards or codes for the execution of steelwork, welding procedure qualification tests performed when new steel materials or welding consumables are applied or on a welding procedure applied at complicated welded joints, and applies to destructive tests conducted for qualification when the welding parameters have been changed.

This part of ISO 10721 specifies the requirements for the fabrication, erection and inspection of structural steelwork in buildings designed in accordance with ISO 10721-1, including steelwork in composite steel and concrete structures. This part of ISO 10721 is also applicable to bridges, off-shore and other civil engineering and related structures, but for such structures it may be necessary to consider other requirements. NOTE For welded connections and for structures subject to fatigue, special considerations regarding scope and field of application are presented in 8.9 and 10.1 respectively of ISO 10721-1.

This Technical Report provides design expressions to determine the characteristic values for the ultimate resistances of components and connections of aluminium structures which are subjected to known static forces.
