With the development of science and technology in the field of structural engineering and also in civil engineering, it is possible to observe the adaptation of pre-engineered buildings in both industrial and residential construction sectors. In this paper, pre-engineered steel building will be design with different parameter using software Staadprov8i and analyzed with different loads on building i.e. dead load, live load, collateral load, wind load and load combinations on building .The main objective of this work is to understand the concepts of PEB and find the least possible weight of structure and various displacement or significance of forces in each direction which will help the structure to be safe and stable. The pre-engineered construction concept involves pre-engineered structure and quality construction systems which will help to minimize the use of cost and time.
Steel Industry is growing rapidly in all the parts of the world .To meet the rising demand of construction, alternative way construction is to be incorporated. In structural engineering, a pre-engineered building (PEB) is designed by a manufacturer to be fabricated using a pre-determined inventory of raw materials and manufacturing methods that can efficiently satisfy a wide range of structural and aesthetic design requirements. The primary framing structure of a pre-engineered building is an assembly of I-shaped members, often referred as I beam. Also the sections used are Tapered sections. In PEB, I section beams used are usually formed by welding together steel plates to form of I section. I section beams are then field-assembled (e.g. bolted connections) to form the entire frame of the pre-engineered building. Advances in technology have greatly improved over the years, contributing tremendously to improving living standards through various new products and services. A pre-engineered building (PEB) is one such revolution. They use a defined stock of raw materials that have been time tested to meet a wide range of structural and architectural design specifications. The majority of steel structures being built are only low-rise buildings, which are generally of one storey only. Industrial buildings, a subset of low-rise buildings are normally used for steel plants, automobile industries, light, utility and process industries, thermal power stations, warehouses, assembly plants, storage, garages, small scale industries etc. They use a defined stock of raw materials that have been time tested to meet a wide range of structural and architectural design specifications. PEB systems are extensively used in industrial and much other non-residential construction world-wide. These buildings were pre-designed or 'pre-engineered' into standard sizes, spans, bays and heights, and use standard details for fixing cladding, roofing, gutters, flashing, windows, doors etc. taking advantage of industrial practices of mass production of components economically. The concept of PEB is the frame geometry which matches the shape of the internal stress (bending moment) diagram thus optimizing material usage and reducing the total weight of the structure. The use of steel structures is not only economical but also eco-friendly at the time when there is a threat of global warming. Here, “economical” word is stated considering time and cost. Time being the most important aspect, steel structures (Pre- fabricated) is built in very short period and one such example is Pre Engineered Buildings (PEB). Pre-engineered building are steel building wherein the framing members and other components are fully fabricated in the factory after designing and brought to the site for assembly, mainly by nut-bolts, thereby resulting into a steel structure of high quality and precision. Steel is an expensive material as compared to the rest but when it comes to the cost-savings during the life span of the structure, steel proves to be a very affordable material . Steel can also be made rust proof by the application of special coated paints . Apart from that, steel is an insect and termite resistant material and the maintenance cost is lower during its life span as compared to other materials. PEB are generally low rise buildings however the maximum eave height can go up to 30 metres, Clear span upto 90 metre wide are possible.
The application of low rise buildings are ideal for showrooms, offices etc. The application of pre-engineered building concepts to low rise buildings is very economical due to its light weight and economical construction. Pre-engineering primary framing structure is an assembly of I-shaped structural members. The I-shaped beams are usually formed in the factory by welding steel plates together to form the I-sections. The I-section beams are then assembled on site with bolted connections to form the entire frame of the pre-engineered building.

II. LITERATURE REVIEW
A. History of PEB
Since then, the use of pre-engineered buildings has spread across Asia and Africa, where the PEB architecture concept has been widely accepted and praised. The principle of pre-engineered steel buildings is known as the most flexible and economical building. In civil construction, the economy and speed of delivery and installation of these buildings are incomparable. No other building system can match the pre-engineered building system in terms of speed and cost from excavation to occupation.

IV. ANALYSIS USING STAAD PRO V8I
StaadProV8i software was used to analyze and design pre-engineered building structures and conventional structures in this project. For the first structure, a pre-designed 3D construction model of a WAREHOUSE building was designed and compared to the conventional structure using conventional steel. In the second example, an 88m wide 2D flat structure was designed with conical sections for PEB, this structure cannot be built by the conventional method as it is not feasible and also not economical for the project. Different spacings between stalls were considered to verify the most adequate.(6)
A. Pre-engineered building by STAAD PRO
StaadproV8i comes with several tools and modes to benefit from a user-friendly interface. Design and analysis can be done side by side to check designs for errors. For PEB design, different dimensions of Conical I sections can be verified for a stable and optimized structure and the same is for conventional steel design, where pre-rolled sections with commercially available dimensions are accessible for design and analysis purposes. STAAD Pro software can be used to analyze and design pre-engineered buildings. It can analyze the bending moment, axial forces, shear forces, torsion, beam stresses of a steel structure so that the design can be done using conical sections and check safety. For the current design, the common stiffness matrix method was used for the structure analysis. Used pre-engineered building members are funneled using the Software's built-in option. The software offers a choice of support options for
our requirements. Here in this project, fixed supports are assigned. For the loads, we manually calculated and assigned them to our structure using the correct steps.

VII. FUTURE SCOPE OF THE STUDY
The future scope of Pre-Engineered Building (PEB) has emerged tremendously after the initiation of various government schemes such as Make In India, Smart City Initiative and with increased approval from the FDI’s demand for infrastructures. This paper represents a well optimized warehouse with least possible weight and different loads values acting on it. The study states that these kinds of buildings provide the required section as per the optimum requirement based on the bending moment. This method has pre-fabricated steel components that are assembled on the site and is lightweight and economical. Times being the controlling factor, the pre-fabricated steel structures are erected in less time and with ease construction on site.
A. In the present days, money is gaining their importance in every sector including the construction industry. Sustainability is what the world is running behind. In all these aspects PEB stands in the top position when compared with other technologies. B. The material used here is not only eco-friendly but also reusable. Steel is the basic material that is used in pre-engineered steel building materials. Infinitely recyclable, steel is the material that reflects the sustainability imperatives. C. A well optimized industrial warehouse will be designed with least possible weight i.e 253.796 KN and analysed by loads and loads combinations parameters. D. The maximum SF and maximum BM for a particular frame will come out for positive and negative envelope 173.901KN (+ve), 41.017 KN (-ve) for beam 76 and 91.107KN-m(+ve), 81.372KN-m (-ve) for beam 42 respectively are given above. E. The most appealing economy of civil construction can be achieved through the efficient use of high-grade steel and composite building form with advanced materials. The model building cost study showed that PEB structure is economical.
