SNI 1726-2019 Structural Design Requirements for Indonesia
SNI 1726:2019: Structural Design Requirements for Indonesian Seismic Code
What is SNI 1726-2019?
Indonesia's Key to Earthquake-Resistant Structures
Indonesia, located within the Pacific Ring of Fire, is prone to frequent earthquakes. To mitigate the risks posed by seismic activities, the country has implemented the Indonesian National Standard (SNI) 1726-2019, a crucial guideline for designing and constructing earthquake-resistant structures.
SNI 1726-2019 is a comprehensive standard that outlines the procedures and requirements for planning and designing structures that can withstand earthquakes. It covers buildings and non-building structures, including residential, commercial, industrial, and infrastructure projects.
This standard is a revision of the previous SNI 1726-2012, incorporating updated knowledge, research findings, and lessons learned from past earthquakes. It provides a more detailed and stringent framework to enhance the seismic performance of structures in Indonesia.
