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.

To counter slower setting of concrete, non chloride-bearing accelerators can be used after approval. Steel conforming to any other international standard may be used provided its strength, elongation, chemical compositipn and bond in concrete, are not inferior to those of Indian Standards. A Is the total area of the cross-section within the outer perimeter, including inner hollow areas. Note: These generally correspond to the maximum load-carrying resistance of a structure or structural member. Open navigation menu. The representative values of commonly used materials are defined in Section 6. The bursting forces in the end blocks, should be assessed on the basis of the ultimate tensile strength. Note Jul at 9 - 41 - 15 PM Document 1 page. Chakrabarti, S. Merani, N. Special care should be taken to identify the section along the member with the critical combination of moments. Where more accurate evaluation of the effective length is required or where end restraint values are less than those specified in a. The sample shall not receive any treatment before testing other than that envisaged in the regular supply of water proposed for use in concrete. Kumar, Vijay E-in-C Retd.

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.

If the manufacturer is not finalised at the time of design, values based on experience shall be used and stated on the drawing or on stressing schedule to enable proper adjustments to be made at site. It will generally be sufficient to consider the maximum and minimum ratios of moment to axial load in designing reinforcement areas and concrete sections. Mas-built is the actual bending moment set up in the structure as constructed. Minimum Yield Stress MPa On the other hand, the discontinuities in the barrier holidays have the tendency to concentrate the corrosion currents in these areas, leading to faster localised corrosion. RE Wall Construction Document 80 pages. Walls and Wall Type Piers Transient Design Situation Design situation that is relevant during a period much shorter than the design working life of the structure and which has a high probability of occurrence. In practice, the limits upto which the secondary effects can be neglected is given in Clause However, before grouting, the tendons shall be considered as unbonded. Necessity of including the second order effects in the analysis is indicated where it is important. Calculated Ls mm 0. Minimum acceptable standards of workmanship are given in Section
