Hai Engineers This Post describes the basic codes for RCC structural design as per Indian standard codes. The structural design of reinforced concrete structures should be carried so as to conform to the Indian codes for reinforced concrete design, published by Bureau of Indian standards.
Following are the design codes in India:
(i) IS456: 2000 – plain and reinforced concrete – code of practice (fourth revision)
(ii) Loading standard codes
The loads to be considered for structural design are specified in the following loading standards:
IS 875 (Part 1 to 5) : 1987 – code of practice for design loads (other than earthquake) for buildings and structures (second revision).
Part – 1: Dead loads
Part – 2: Imposed (Live) loads
Part – 3: Wind loads
Part – 4: Snow loads
Part – 5: Special loads and load combinations
IS 1893: 2002 – criteria for earthquake resistant design of structure (fourth revision).
IS 13920: 1993 – ductile detailing of reinforced concrete structures subject to seismic forces.
Purpose of design codes:
National building codes have been formulated in different countries to lay down guidelines for the design and construction of structures. The codes have been evolved from the collective wisdom of expert structural engineers, gained over the years. These codes are periodically revised to bring them in line with current research, and often current trends.
Design Handbooks:
The bureau of Indian Standards have also published the following handbooks which serve as useful supplement to the 1978 version of the codes. Although the handbooks need to be updated to bring them in line with the recently revised (2000 version) of the code, many of the provisions continue to be valid (especially with regard to structural design provisions).
SP 16 – 1980 – Design Aids (for Reinforced Concrete) to IS456: 1978
SP 24: 1983 – Explanatory handbook on IS 456: 1978
SP34: 1987 – Handbook on Concrete Reinforced and Detailing.
