What is IS 1893 Part 4?




IS 1893 Part 4 is a part of a series of standards that deal with earthquake resistant design of structures in India. The other parts are:



  • Part 1: General provisions and buildings



  • Part 2: Liquid retaining tanks - elevated and ground supported



  • Part 3: Bridges and retaining walls



  • Part 5: Dams and embankments



IS 1893 Part 4 was published in 2005 by the Bureau of Indian Standards (BIS), which is the national standards body of India. It covers the design and construction of industrial structures including stack-like structures, such as chimneys, silos, cooling towers, blast furnaces, and other similar structures. It provides guidelines for determining the seismic loads, the design parameters, the analysis and design methods, and the design considerations and detailing for these structures.


Why is IS 1893 Part 4 important?




IS 1893 Part 4 is important because it helps to ensure the safety and performance of industrial structures including stack-like structures in earthquake-prone areas. India is a country that has experienced some devastating earthquakes in the past, such as the 2001 Bhuj earthquake, the 1993 Latur earthquake, and the 2005 Kashmir earthquake. These earthquakes have caused significant damage and loss of life to various types of structures, including industrial structures.


Industrial structures including stack-like structures are particularly vulnerable to earthquake effects because of their height, slenderness, mass distribution, and dynamic characteristics. They can experience large displacements, stresses, and vibrations during an earthquake, which can lead to structural failure or collapse. Therefore, it is essential to design and construct these structures in accordance with IS 1893 Part 4, which takes into account the seismic hazard, the structural behavior, and the ductility requirements for these structures.


By following IS 1893 Part 4, industrial structures including stack-like structures can achieve the following benefits:



  • Reduce the risk of structural damage and collapse during an earthquake



  • Protect the lives and property of the occupants and users of these structures



  • Prevent or minimize the environmental and economic impacts of these structures



  • Enhance the resilience and functionality of these structures after an earthquake

How to use IS 1893 Part 4?




If you have downloaded IS 1893 Part 4 PDF from any of the official sources, you can use it as a reference for designing and constructing industrial structures including stack-like structures. However, you need to have some basic knowledge and skills in structural engineering, earthquake engineering, and relevant codes and standards. You also need to have access to appropriate software and tools for performing the analysis and design of these structures.


IS 1893 Part 4 consists of six sections and four annexures. The sections are:



  • Scope and general



  • Seismic zoning and design parameters



  • Analysis and design methods



  • Design considerations and detailing



  • Industrial structures



  • Stack-like structures



The annexures are:



  • Annex A: Seismic zone map of India



  • Annex B: Response spectrum curves



  • Annex C: Ductility classes and performance levels



  • Annex D: Examples of industrial structures including stack-like structures



To use IS 1893 Part 4, you need to follow these steps:



  • Determine the scope and general provisions of the standard that are applicable to your structure, such as the definitions, symbols, notations, assumptions, and references.



  • Determine the seismic zoning and design parameters of your structure, such as the seismic zone factor, the importance factor, the response reduction factor, and the design horizontal acceleration spectrum.



  • Select an appropriate analysis and design method for your structure, such as the equivalent static method, the response spectrum method, the time history method, or the modal analysis method.



  • Perform the analysis and design of your structure using the selected method and considering the design considerations and detailing requirements of the standard, such as the ductility requirements, the foundation design, the connection design, and the reinforcement detailing.



  • Check the compliance of your structure with the specific provisions for industrial structures or stack-like structures given in the standard, such as the stability criteria, the wind load effects, the thermal load effects, and the dynamic amplification factors.



  • Prepare the drawings, specifications, and documentation of your structure according to the standard and other relevant codes and standards.



What are some examples of industrial structures including stack-like structures?




Industrial structures including stack-like structures are those structures that are used for industrial purposes and have a stack-like shape or feature. Some examples of these structures are:



  • Chimneys: These are vertical structures that are used to vent smoke or gases from boilers, furnaces, or fireplaces. They can be made of brick, concrete, steel, or other materials. They can have different shapes and sizes depending on their function and design.



  • Silos: These are cylindrical or conical structures that are used to store bulk materials such as grains, cement, coal, or wood chips. They can be made of metal, concrete, wood, or other materials. They can have different heights and diameters depending on their capacity and design.



  • Cooling towers: These are tall structures that are used to cool water or air by evaporating a small amount of water. They can be used for power plants, chemical plants, or other industrial processes. They can be made of concrete, steel, wood, or other materials. They can have different shapes such as natural draft, mechanical draft, or hyperbolic.



  • Blast furnaces: These are large structures that are used to produce iron from iron ore by smelting. They can be made of steel or other materials. They can have different heights and diameters depending on their output and design.



These are some examples of industrial structures including stack-like structures that follow IS 1893 Part 4 for their earthquake resistant design. You can find more examples in Annex D of IS 1893 Part 4 PDF.
