The advancement in the pre-engineered building construction approach involves time limitation, cost-effectiveness, improved structural behaviour and advanced architectural view. Pre-engineered buildings are becoming an effective replacement of conventional steel buildings in every aspect. It shows more advanced results in case of cost comparison, construction time, quality parameters and architectural point of view. The main objective of the current study is to compare pre-engineered steel buildings and conventional steel building in every aspect. A pre-engineered building was designed and then comparative analysis was done concerning a conventional building with the same configuration. The software which was mainly used for the entire designing and analysis part was Bentley STAAD PRO and it was found that the Pre-engineered building gives more sustainable results as compared to conventional steel buildings. It was also found that, if the construction process was according to conventional methods it will be more time consuming and more budget consuming at every aspect, so pre-engineered buildings usage should be implemented as the construction as well as the maintenance cost of pre- engineered buildings is very less as that of conventional steel buildings...In this project work we have compare parametric evaluation of pre –engineered building (PEB) and conventional industrial sheds of length 120m and width 60m under the influence of moving crane loads for both pinned support and fixed support using STAAD Pro. Key Words: Max. Displacement, Time period ,Base shear, STAAD Pro .etc. 1.INTRODUCTION India being a developed country massive house building construction is taking place in various parts of the country. Since 30% of Indian population lives in towns and cities; hence construction is more in the urban places. The requirement of housing is tremendous but there will always be a shortage of house availability as the present masonry construction technology cannot meet the rising demand every year. Hence one has to think for alternative construction system for steel or timber buildings, but timber is anyway not suitable to tropical countries like India.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. Within some geographic industry sectors these buildings are also called Pre-Engineered Metal Buildings. Historically, the primary framing structure of a pre- engineered building is an assembly of I- shaped members, often referred as I beam. 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. Cold formed Z and C-shaped members may be used as secondary structural elements to fasten and support the external cladding. Roll-formed profiled steel sheet, wood, tensioned fabric, precast concrete, masonry block, glass curtain wall or other materials may be used for the external cladding of the building.In order to accurately design a pre-engineered building, engineers consider the clear span between bearing points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection criteria, internal crane system and maximum practical size and weight of fabricated members. Historically, pre-engineered building manufacturers have developed pre-calculated tables for different structural elements in order to allow designers to select the most efficient beams size for their project. In pre-engineered building concept the complete designing is done at the factory and the building components are brought to the site in CKD ( Completely knock down condition). These components are then fixed / jointed at the site and raised with the help of cranes. The pre- engineered building calls for very fast construction of buildings and with good aesthetic looks and quality construction. Pre-engineered Buildings can be used extensively for construction of industrial and residential buildings. The buildings can be multi storied (4-6 floors). These buildings are suitable to various environmental hazards. Pre-engineered buildings can be adapted to suit a wide variety of structural applications; the greatest economy will be realized when utilizing standard details. An efficiently designed pre- engineered building can be lighter than the conventional steel buildings by up to 30%. Lighter weight equates to less steel and a potential price savings in structural framework.
