Preface The basic requirements of good reinforced concrete detailing are clarity and conciseness. Unfortunately, there has been a steady deterioration in the quality and quantity of drawings supplied for reinforced concrete over the last twenty years. The net result of poor quality drawings is increased costs in the material supply and construction sectors and unacceptable levels of dispute. Detailing of reinforcement is the interface between the actual design of the concrete structure and what is to be constructed. There is no point in having the most sophisticated analysis and design if it cannot be constructed in the field. Designers must be aware of practical limitations of construction. Detailing is also important for durability, as poor placement of reinforcement leads to insufficient cover and long term problems. Detailing of reinforcement is not taught to designers and yet it is fundamental to the proper design of reinforced concrete. Unlike some countries (and in particular the United Kingdom) reinforcement is scheduled
This is the fourth edition of the “Reinforced Concrete Detailing Manual”; first published in 1975; and rewritten in 1988 to match the publication of AS 3600. Substantial sections of this document remain unchanged from the 1988 edition prepared by Mr. Brian Ferguson and his committee. However, the review team has addressed the following issues: ■ Progressive revisions of AS 3600 and incorporation of the provisions of AS 3600:2009. ■ Introduction of 500 MPa reinforcing steel. The standardisation of steel strength for both mesh and bar and the increased focus on ductility has affected how and where reinforcing steel is used. The increase in strength has also necessitated the revision of bond and anchorage lengths. ■ Detailing for seismic response. The 1998 edition was published prior to the Newcastle Earthquake. This edition has taken the opportunity to discuss detailing issues, which affect the safety and ductility of concrete structure under extreme seismic events. ■ Update diagrams and drawings to comply with new edition of AS 1100.501. The Concrete Institute of Australia is pleased to acknowledge the valuable contribution of the following people and organisations: ■
