This paper is sequel to the first paper on comparison of general detailing practice for reinforcement and prestressing cables between past and the present code of Indian Roads Congress IRC Covering Section 15 of IRC: This paper covers the comparison of detailing requirements for specific structural members as covered in Section 16 of IRC: and provisions on ductile detailing for seismic resistance as covered in Section 17 of IRC: The code is less prescriptive and offers greater choice of design and detailing methods with scientific reasoning. This new generation code, when used with full understanding, will bring benefits to all sectors of society, as it will eventually lead to safer construction and make a tangible contribution towards a sustainable society. The present situation in the industry is that most of the consulting offices are struggling to understand this code, which is not so user-friendly. Since the designer is hard pressed for time, the majority of consultants are unfortunately spending their valuable time only in fulfilling the prescribed rules of the code, acting as a technical lawyer, with very little understanding of the subject. One of the useful methods of understanding the new code in the short term is by comparing the provisions of this code with the previous practice that used to be followed prior to publication of this code. This paper is written with this objective in mind. Toggle navigation Menu. Detailing provisions of IRC compared with previous codes i.

The relative stiffness of members should be based on the concrete or gross transformed irc 112 2011 properties as described in Clause 7. The grade designations, definitive properties and other properties, as adopted by the relevant Indian Standards, are given in Section 18 Table In the absence of other data, v may be taken as 0.

The Official amendments to this document which may be considered necessary from time to time would be published by the IRC in its periodical Indian Highways These shall be considered as effective and as part of the Code etc. New Delhi. Mizoram, Aizawl Sinha, A. Cement Concrete Plain and Reinforced ; IRC: 21, both based on working stress method, were first published in December 1 and October 1 respectively. The last revisions of these two documents were carried out in the year These two codes stands withdrawn on publication. The past two decades have seen unprecedented growth of knowledge in the field of concrete bridges, development of new structural forms, new methods of computer-based analysis and design and development of high strength materials. The need for a new rationalized. The object of issuing the new Code of Practice for Concrete Road Bridges is to establish a common procedure for design and construction of road bridges in India based on the limit state method.

Ik can be taken as 0. Rating: 3. All provisions of the Code may not be applicable for hybrid structural systems, or for structures using other types of concrete. Co-convenor Viswanathan, T. Ninan, R. Design verification for shear is carried out at Ultimate Limit State of strength only. IRC Loading Document 18 pages. Both the effects should be considered in selection of design prestressing force. There are no reviews yet. The general principles as well as normally used methods are covered in Section 7. Minimum acceptable standards of workmanship are given in Section Mix design shall be modified if it does not meet the acceptance criteria. Ibrahim Arabi. As a result stress-strain relationship is modified.

Notification No.

Note: These generally correspond to the maximum load-carrying resistance of a structure or structural member. The grade designations are as adopted by the relevant standards. In calculation of area of transverse reinforcement, the steel provided for any other reason such as distribution steel in slabs or shear reinforcement in beams, can be counted. These effects include the distribution of internal forces and moments as well as stresses, strains, curvatures, rotations and displacements in static or dynamic modes. Chakraborty, Prof. Presentation Coupler System Document 21 pages. The contribution of creep to total strain is different at loading and unloading stages. One of the useful methods of understanding the new code in the short term is by comparing the provisions of this code with the previous practice that used to be followed prior to publication of this code. For Later. Secretary 3. Stiffness constants based on the section properties as used for the analysis of the structure at the serviceability limit state, may be used in the analysis. II II.
