Steel Detailers' Manual

This highly illustrated manual provides practical guidance on structural steelwork detailing. It:

· describes the common structural shapes in use and how they are joined to form members and complete structures

· explains detailing practice and conventions

· provides detailing data for standard sections, bolts and welds

· emphasises the importance of tolerances in order to achieve proper site fit-up

· discusses the important link between good detailing and construction costs

Examples of structures include single and multi-storey buildings, towers and bridges. The detailing shown will be suitable in principle for fabrication and erection in many countries, and the sizes shown will act as a guide to preliminary design.

The third edition has been revised to take account of the new Eurocodes on structural steel work, together with their National Annexes. The new edition also takes account of developments in 3-D modelling techniques and it includes more CAD standard library details.

STEEL DETAILERS' MANUAL THIRD EDITION ALAN HAYWARD, FRANK WEARE AND ANTHONY OAKHILL

Steel remains the optimum choice for structural projects. Architects, engineers and construction companies turn to steel to provide exciting, stimulating structures which meet the needs of a diverse range of clients, occupiers and users. To remain competitive, steelwork contractors have turned to new technologies to minimise costs and meet tight project deadlines.

Steelwork detailing plays a pivotal role in the successful creation of any steel structure. The Steel Detailers' Manual provides an introduction and guide to this essential skill for those in the constructional steelwork industry.

The third edition has been revised to take account of some aspects of Eurocode 3 on structural steel work. The new edition also takes account of developments in 3-D modelling techniques and it includes more CAD standard library details. As a highly illustrated guide on structural steelwork detailing, it:

• describes the common structural shapes in use and how they are joined to form members and complete structures
• explains detailing practice and conventions
• provides detailing data for standard sections, bolts and welds
• emphasises the importance of tolerances in order to achieve proper site fit-up
• discusses the important link between good detailing and construction costs

Examples of structures include single and multi-storey buildings, towers and bridges. The detailing shown is suitable in principle for fabrication and erection in many countries, and the sizes shown will act as a guide to preliminary design.
