Economical Design for Dairy Farm Structures
Abstract
In this study a steel framed dairy farm structure designed by considering IS 800-2007. It has been observed that by following the code recommendations for the design of dairy farm structures, it becomes expensive, that an ordinary farmer can't afford it. The basic idea of the investigation is to make these structures more economic for the farmers so that they become affordable. It is proposed to take realistic approach viz-a-viz applicable codes in design of these structures to make them safe and economical. The analysis and design will be done using ETABS software. The factors such as structural capacity and cost involved will be focused in the study.

Introduction
India is agrarian country. Agriculture is the profession of more than 75% of the population of the country and dairy farming comes along with it. Dairying is an important source of subsidiary income to small/marginal farmers and agricultural labors. Dairy producers aim to ensure that the safety and quality of their raw milk will satisfy the highest expectations of the food industry and consumers.
The total milk production in the country for the year 2018-19 was estimated at 189 million metric tonnes and the demand is expected to be 230 million tonnes by 2022. To achieve this demand annual growth rate in milk production has to be increased from the present 6.5 % to 9%. Thus, there is a tremendous scope for increasing the milk production through profitable dairy farming. Thus, understanding the requirements for dairy farm structures gain attention of this study.
This includes study of geometry of structure. The structure is used mainly by animals for living purpose. Different areas are to be made for resting and feeding them. These structures are situated in farms which are plain terrains. All these put challenges in selecting the shape and size columns. Therefore, careful designing is essential.
The productivity of animals in India is not as much to justify the cost of production of safe milk. Therefore, farmers look for lower costs. Even the financial institutions stress to lower the cost for better feasibility and sustainability of these farms. Hence the thorough study is needed to lower down the costs of these structures.
Conclusion
It is observed that 15̊roof slope proves ideal for designing of dairy farm shed.
The reduced wind loads made it possible to reduce section sizes to very small as compared to conventional 22̊ roof slope model.
The total savings in quantity of steel is found to be close to 30%.
