Standard Specifications and Code of Practice for Road Bridges, Section-II Loads and Load Combinations (Seventh Revision)
IRC 6 Section-II (2017) specifies the standard loads and load combinations for the design of road bridges in India, including vehicular, wind, seismic, earth pressure, and barge impact loads. It provides detailed guidance on applying these loads in limit state design, addressing various bridge types and terrains. This standard is essential for civil and structural engineers involved in the design, analysis, and safety evaluation of road bridges to ensure structural integrity under diverse loading conditions.
