Industrial Buildings are designed for wind loads in the transverse direction as steel lattice towers are less sensitive to earthquake loads. Recent times the collapse of transmission lines towers, under wind loading, has been increasing. Although the damages are controllable the threat under wind hazard is big concerns for designers. Similarly, the seismic analysis of Industrial Building is equally important as the response due to an earthquake may be severe than due to wind load. Recent cases of damage to Industrial Building during earthquake are during the 1994 Northridge earthquake two Industrial Building collapsed due to large ground motion, during the 1999 Chi-Chi earthquake led to blackouts in the central and northern regions of Taiwan The main aim of the study provides which method is most economical method and, high bending strength, more load carrying capacity and high flexural strength by analysis of both working stress and limit state method. An investigation of the seismic response of an existing industrial steel building is presented in the following. Starting from as-built data collection, the study has been addressed to develop the complete process of seismic risk assessment, through the use of current performance-based analysis methods. This paper is focused on the main modelling aspects and results from analysis of seismic performance upon integration with site-specific hazard, the structural risk assessment, that is, a probability of failures. These buildings require large and clear areas unobstructed by the columns. The large floor area provides sufficient flexibility and facility for later change in the production layout without major building alterations. The industrial buildings are constructed with adequate headroom for the use of an overhead traveling crane. There are various international codes available for the design of steel structures. Developments are still going on, to achieve the great economy by using different methods as well as by using different codes of practice. By using this study, we can make a relation between the different parameter of codes, to achieve the above goals of a structural engineer.

INTRODUCTION Any building utilized by the business to oblige the creation movement, stock crude materials, stock completed item before supply is known as a modern building. Rooftop support and entryway outline are utilized to cover and sanctuary the zone of a mechanical building. According to the prerequisite of a modern building, the reasonable sort of rooftop support and gateway outline is used. Rooftop support is intended for dead load, live load, wind stack, and their blends according to Indian Standards. An economy of a modern building relies upon the arrangement of structure, kind of rooftop bracket and gateway outline used, powers following up on building and determination of steel segments required according to drive utilized. A Structural steel is a material utilized for steel development, which is framed with a particular shape following certain norms of concoction creation and quality. They can likewise be characterized as hot moved items, with a cross area of extraordinary shapes like points, channels and pillars/joists. There has been an expanding interest for auxiliary steel for development purposes in India. Steel has dependably been more wanted to concrete since steel offers better strain and pressure in this manner bringing about lighter development. Typically, auxiliary steel utilizes three-dimensional supports henceforth making it bigger than its solid partner. Preference of steel as a basic material is that the basic steel displays attractive physical properties that make it a standout amongst the most adaptable basic materials being used. Its awesome quality, consistency, light weight, usability, and numerous other attractive properties settle on it the material of decision for various structures, for example, modern structures, steel spans, elevated structures, towers, and other structure. 2. COMPONENT OF AN INDUSTRIAL BUILDING The elements of industrial buildings are listed below: (1) Purlins (2) Sag rods
