IS 1893 (Part 4) : 2015 - Criteria for Earthquake Resistant Design of Structures - Industrial Structures Including Stack - Like Structures
This standard covers the earthquake resistant design of industrial structures, including stack-like structures, shall be designed and constructed to resist the earthquake effects and also provides the estimate of earthquake forces for design of such structures.
The standard includes detailed provisions on general principles including ground motion (including necessary assumptions and increase in permissible stresses); design spectrum to be used and the seismic coefficients; categorization of industrial structures; detailed design criteria which includes design loads, load combinations, special design factors, etc.
It also provides specific requirements for stack like structures which includes the design criteria; time period of vibration; design seismic force; dynamic analysis and special considerations for reinforced concrete stakes.
