Recently, the Bureau of Indian Standards shared the draft version of IS 1893:2023 for commentary purposes. This standard represents the criteria for the earthquake-resistant design of structures. The draft version of IS 1893 is set to introduce significant changes in the methodology of designing earthquake-resistant structures.

IS 1893 : 2023 Draft Version

The draft version of IS 1893 : 2023 is circulated by bureau of indian standard on April 2023 for the initial commentary from the end users. The format for sending comments on BIS Documents is given in the draft version of IS 1893.
