Abstract - For a design engineer the integrity, safety and
superseding IS 800:1984 which was based of Working Stress Method.
economic feasibility of the structure are of utmost importance. In the earlier general code of constructions in steel (i.e., IS 800: 1984), the design philosophy used was the Working Stress Method which ensures that the working stress in the member is computed under the action of the working loads, and is less than the permissible stress. Since this method was focusing only on the serviceability at working loads, the Limit State Method of design was introduced in the latest revision of code (i.e., IS 800:2007). This approach for design is based on attainment of the relevant limit state. Since in India it was introduced recently, it is an important task to study these two design philosophies so as to find most appropriate and economical design philosophy as per the requirement of the design engineer. As a result, we looked at a variety of literature evaluations on this topic, which is significant in the industry. We completed our analysis on such a structure because there were no articles especially on long span large height industrial sheds. This paper presents, the comparative study of the Working Stress Method (WSM) and Limit State Method (LSM) through analysis and design of a large span and a large height industrial shed equipped with gantry girder and the results are concluded in the form of tables and graphs.
1.1 Aim & Objective The aim of this paper is to compare a Large Span and Large Height Industrial Shed by Limit State method and Working Stress method of design. Thus, the objective is to Analyze and Design an Industrial Shed using Limit State Method and Working Stress Method and to compare both the methods in order to present a more cost-efficient structure.
2. LITERATURE REVIEW Various research papers have been presented by the researchers till date. Some important papers are discussed below: Prof. Ravindra Bhimrao Kulkarni and Rohan Shrikant Jirga published a paper on the design of tension members using the limit state approach and the working stress approach. For both equal and unequal angles, comparisons were made using design samples, charts, and graphs. They came to the conclusion that designing tension members using angle sections by the limit state approach is more cost effective than using the working stress approach, which saves between 12 to 54 % of economy [1].

1. INTRODUCTION
M. Krishnamoorthy and D. Tensing conducted research on compression member design using IS 800: 2007 and IS 800: 1984, comparing the design of columns with both ends fixed based on strength to weight ratio and load carrying capacity against different sections for column lengths of 2m, 3m, and 4m. In this study, they manually designed column members using FOS, load combinations using respective design methodologies and showed comparable results using graphs for different concepts. As a result, it was determined that WSM has a marginally larger percentage of load-carrying capacity than LSM, and the strength-to-weight ratio is governed by weight per unit length [2].
We are living in an age that is dominated by the wonders of technology. Globalization has influenced architecture and evolved from short stone and wood structures to steel structures. Today, many buildings and infrastructure are built with structural steel which has made it the world’s most dependable building material. The current growth in industrialization is greatly influenced by the development of structural steel as a building material mainly since they are sturdy, long-lasting, and easy to construct. Steel structures are utilised for a range of structures in modern construction, including massive industrial buildings. An Industrial shed is generally a steel structure that can be used for various purposes.IS 800:2007 was introduced as limit state method of design for steel structures
