Measures To Protect Urban Infrastructure
Site selection : The project site should be away from the active fault lines. It should be done with the help of GIS seismic mapping.
Structure of earthquake-prone areas Following code need to be followed till they are revised
Priority for finalising earthquake-resistant design and construction related codes by the BIS:
1. IS:1893 (Part 2) :: Elevated and Ground Supported Liquid Retaining Structures, (Part 3) :: Bridges and Retaining Walls, and (Part 5) :: Dams and Embankments
2. IS:4326 :: Earthquake Resistant Construction
3. IS:13920 :: Ductile Detailing of Reinforced Concrete Structures
4. IS:13827 :: Earthen Dwellings
5. IS:13828 :: Low Strength Masonry Structures
6. IS:13935 :: Seismic Strengthening of Structures
BIS codes are already mentioned in the Model Town Planning Act. Now, it is required that codes related to construction activities in earthquake zones should be strictly incorporated in the project. It should be supervised by the ULB/DDMA based on the extent of the project. While preparing for a project in a earthquakeprone area, following points should be checked by the ULB/DDMA regarding structure of building and other infrastructure:
· No relaxation in building plans which violate safety parameters in relation to earthquake safety will be permissible.
· While revising the DCRs and master plans, special attention should be paid to ensure that the seismic risk and vulnerabilities of existing buildings to withstand high-intensity earthquakes before allowing any relaxation relating to approvals for additional floors.
