Sees  \nThis document provides standards of practice for both the architect/engineer (A/E) and reinforcing steel detailer in showing reinforcing steel details. It is divided into three parts: one addressed to the A/E, one for the detailer, and a third providing a reference table and figures. It defines the responsibilities of both the A/E and detailer. It then establishes certain standards of practice for both the structural and placing drawings.  \nKeywords: beams (supports); bending (reinforcing steels); bridges (structures); buildings; columns (supports); concrete slabs; detailing; drafting (drawing); fabrication; floor systems; foundations; hooked reinforcing steels; microcomputers; placing drawings; reinforced concrete; reinforcing steels; splicing; stirrups; structural design; structural drawings; ties; tolerances (mechanics); walls; welded-wire fabric.  \nCONTENTS  \nPart A—Responsibilities of the architect/engineer Chapter 1—Structural drawings, p. 315-2  \n1.1—General  \n1.2—Drawing standards  \n1.3—Structural drawings—Buildings and other structures  \n1.4—Structural drawings—Highway and transportation structures  \nChapter 2—Standards of practice, p. 315-3  \n2.1—General  \n2.2—Tolerances  \n2.3—Bar lengths  \n2.4—Hooks and bends  \n2.5—Beams and girders  \n2.6—Columns  \n2.7—Development and splices of reinforcing steel  \n2. 8—Joint details  \n2.9—Reinforcing steel supports  \n2.10—Special details for seismic design of frames, joints, walls, diaphragms, and two-way slabs  \n2.11—Corrosion-resistant coatings for reinforcing steel  \nPart B—Responsibilites of the detailer Chapter 3—Placing drawings, p. 315-10  \n3.1—Definition  \n3.2—Scope  \n3.3—Procedure  \n3.4—Drawing standards  \n3.5—Building drawings  \n3.6—Highway drawings  \n3.7—Detailing to fabricating standards  \nChapter 4—Fabricating practice standards, p. 315-15  \n4.1—Fabrication  \n4.2—Extras  \n4.3—Tolerances  \nChapter 5—Supports for reinforcing steel, p. 315-16  \n5.1—General  \n5.2—Types of bar supports  \n5.3—Side form spacers and beam bolsters  \n5.4—Placing reinforcing steel supports  \nChapter 6—Computer-assisted detailing, p. 315-16  \n6.1—Use of computers in detailing  \n6.2—Placing drawings  \n6.3—Ordering procedures  \nChapter 7—Recommended practices for location of bars designated only by size/spacing, p. 315-17  \nACI 315-99 supersedes ACI 315-92 and became effective August 31, 1999.

This added degree of sophistication has resulted in more complex structures being designed and built with structural members that have long spans, shallow depths, and contain a high percentage of reinforcing steel.  \nIn the past, during the course of developing placing drawings, the detailer often suggested solutions in areas where the details were incomplete and where","cbCaiq1ipMNgOZ2l","https://ap.wps.com/l/cbCaiq1ipMNgOZ2l","pdf",1164706,44,"English","# Part A—Responsibilities of the architect/engineer\n## Chapter 1—Structural drawings\n## Chapter 2—Standards of practice\n# Part B—Responsibilites of the detailer\n## Chapter 3—Placing drawings\n## Chapter 4—Fabricating practice standards\n## Chapter 5—Supports for reinforcing steel\n## Chapter 6—Computer-assisted detailing\n## Chapter 7—Recommended practices for location of bars\n# Part C—Figures and tables\n## Foreword\n## Chapter 8—Glossary\n## Chapter 9—References\n## Chapter 10—Notations","[{\"question\":\"What is ACI 315-99 meant to standardize?\",\"answer\":\"It standardizes how reinforcing steel details are shown, defining responsibilities for both the architect/engineer (A/E) and the reinforcing steel detailer, including standards for structural and placing drawings.\"},{\"question\":\"How does ACI 315-99 split the responsibilities between the A/E and the detailer?\",\"answer\":\"The A/E prepares the structural design to meet applicable building code requirements and provides enough contractual definition to convey detailing requirements.
