IS 1893 : Part 1 : 2025 Design Earthquake Hazard and Criteria for Earthquake-Resistant Design of Structures - Code of Practice - Part 1 General Provisions
1 SCOPE
1.1 This standard (Part 1) primarily specifies the minimum design earthquake hazard and criteria to be considered in the earthquake-resistant design of structures. Additionally, it outlines the principles of earthquake-resistant design, desirable and unacceptable features of earthquake-resistant structural system configurations, and methods of analysis and treatment of geotechnical aspects for all types of structures. Additional requirements pertaining to different types of structures are dealt separately within IS 1893 (Part 2) to (Part 11).
1.2 Structures, like multi-level parking structures, security cabins (which guard important, critical and special structures), and ancillary structures (like water and sewage treatment plants, and electrical sub-stations) associated with important, critical and special structures need to be designed for appropriate earthquake effects as per this standard.
