FOREWORD: Users of various civil engineering codes have been feeling the need for explanatory handbooks and other compilations based on Indian Standards. The need has been further emphasized in view of the publication of the National Building Code of India in 1970 and its implementation. The Expert Group set up in 1972 by the Department of Science and Technology, Government of India carried out in-depth studies in various areas of civil engineering and construction practices. During the preparation of the Fifth Five-Year Plan in 1975, the Group was assigned the task of producing a Science and Technology plan for research, development and extension work in the sector of housing and construction technology. One of the items of this plan was the production of design handbooks, explanatory handbooks and design aids based on the National Building Code and various Indian Standards and other activities in the promotion of the National Building Code. The Expert Group gave high priority to this item and on the recommendation of the Department of Science and Technology, the Planning Commission approved the following two projects which were assigned to the Bureau of Indian Standards :
a) Development programmc on code implementation for building and civil engineering construction, and
b) Typification for industrial buildings.
A Special Committee for Implementation of Science and Technology Projects (SCIP) consisting of experts connected with different aspects was set up in 1974 to advise the BlS Directorate General in identification and for guiding the development of the work. Under the first programme, the Committee has so far identified subjects for several explanatory handbooks/compilations covering appropriate Indian Standards codes specifications which include the following :
Design Aids for Reinforced Concrete to IS : 456-1978 (SP : 16-1980)
Explanatory Handbook on Masonry Code (SP : 20-1981)
Explanatory Handbook on Codes of Earthquake Engineering (IS : 1893-1975 and IS : 4326-1976) (SP : 22-1982)
Handbook on Concrete Mixes (SP : 23-1982)
Explanatory Handbook on Indian Standard Code of Practice for Plain and Reinforced Concrete (IS : 456-1978) (SP : 24-1983)
Handbook ‘on Causes and Prevention of Cracks in Buildings (SP : 25-1984)
Summaries of Indian Standards for Building Materials (SP : 2 -I 983)
Functional Requirements of industrial Buildings (Lighting and Ventilation) (SP : 32-1986)
ng (SP : 35-1987)
Timber Engineering (SP : 33-1986)
Water Supply and Drainage with Special Emphasis on Plumbir
Functional Requirements of Buildings*
Foundation of Buildings
Steel Code (IS : 800-1984)
Building Construction Practices
Bulk St,orage Structures in Steel
Construction Safety Practices
This Handbook provides information on properties of reinforcing steel and &ta-iling requirements, including storage, fabrication, assembly, welding and placing of reinforcement in accordance with IS : 456-1978. ‘As a result of the introduction of limit state method ‘of design for reinforced concrete structures and the concept of development length, detailing has become extremely important as many of the design requirements are to be’ met through detailing. This Handbook is expected to guide the designer in detailing which include correct positioning of bare for a particular type of structural element and preparation of bar bending schedule. The detailing requirements as specified in IS : 456- 1978 have. been brought out as applicable to different structural elements in a building and explamed, wherever necessary. The relevant Indian Standards and other literature available on the subject have been taken into consideration in preparing the Handbook. The Handbook will be useful to concrete design engineers, field engineers and students of civil engineering.
Some of the important points to be kept in view in the use of the Handbook are :
a) The reinforcement has to cater to forces (bending moment, shear force, direct compression or direct te,nsion) at sections consistant with development length requirements at the particular section. Sound engineering judgement shall be exercized while applying the provisions herein and detailing should be such that the structural element satisfies the requirements of performance for which it is meant. Typical detailing drawings are included to illustrate one possible method of arrangement of bars for a particular condition. They should not be construde as the only possible method.
b) 4 Considering the importance of ductility requirements in structures subjected to severe earthquakes, a separate section is included on the detailing requirements for buildings in severe earthquake zones (Zones IV and V of IS : 1893-1984).
c) International Standard IS0 4066-1977 ‘Buildings and civil engineering drawings- Bar scheduling’ is reproduced in the Handbook.
d) The Handbook does not form part of any Indian Standard on the subject and does not have the status of an Indian Standard. In case of dispute about interpretation or opinion expressed in the Handbook. The provisions of relevant Indian Standard only shall apply. The provisions of the Handbook particularly those relating other literature should be considered as only supplementarr information.
e) The Handbook is expected to serve as a companion document to the three handbooks already published on the subject of reinforced concrete, namely, SP : 16-1980,
SP : 23-1982 and SP : 24-1983.
f) AlI dimensions are in mm unless otherwise specified.
The Handbook is based on the first draft prepared by the Central Public Works Depart-ment, New Delhi. Shri B. R. Narayanappa. Deputy Director, and Shri P. S. Chadha, Officer on Special Duty, Bureau of Indian Standards (BIS). were associated with the work. The assistance rendered by Shri A. C. Gupta, Assistant Chief Design Engineer, National Thermal Pdwer Corporation (NTPC), New Delhi, in the preparation of this Handbook specially in the formulation of drawings is acknowledged.
The draft Handbook was circulated for review to National Council for Cement and Building Materials, New Delhi; Structural Engineering Research Centre, Madras; Indian institute of Technology, Madras; Indian Institute of Technology, New Delhi; Andhra Pradesh Engineering Research Laboratories, Hyderabad; Engmeering Construction Corporation Ltd. Madras; Engineer-in-Chiefs Branch, Army Headquarters, New Delhi; Engmeering Consultants (India) Limited, New Delhi; Gammon lndia Ltd, Bombay; M/s C. R. Narayana Rae, Architects & Engineers, Madras; STUP Consultants Ltd, Bombay; Research, Design and Standards Organization, Ministry of Railways, Luclcnow; Irrigation Department, Government of Gujarat; M/s H. K. Sen and Associates, Calcutta; Siddharth Shankar and Associates (Consulting Engineers), New Delhi; Roy and Partners (Architects & Engineers), New Delhi; Shrish Malpani (Architects & Engineers), New Delhi; and the views received were taken into consideration while finalizing the Handbook.
