Abstract - For a construction of single storey industrial
building the pre-engineered building (PEB) is a new thought in the construction field. It is a concept of steel structures introduced in early 1960’s. In this type of construction the entire structure uses of built up “I” sections, the main advantage in this concept is no welding process will be carried out in the site. The structure will be designed and manufactured in the plant and are transported to the site and then erected. The sectional properties will depends on the moments at those specific locations hence there won’t be any excess of steel utilisation. In this study, an industrial ware house is analyzed and designed according to Indian standards, I.S. 800-2007 and also referring MBMA- 2002/AISC-89 with members built up, rectangular and tapered sections. In this study, a structure with a length of 30m,width of 20m, clear height of 9m and roof slope of 1: 10 is considered to carry out analysis and design(The members are assigned with the built up sections of rectangle and tapered sections). The behaviour and economy of the structure is discussed with respect to its analysis results and weight, between Indian code (IS 800 -2007) and American code (MBMA- 2002, AISC-89). In this study the structures considered was analyzed and designed with structural engineering software STAAD.Pro.
duration and more expenditure, hence construction stages consumes more time and cost it results in an uneconomical. In these, type of buildings the all fabrication is done in factory, based on the design, pre fabrication is been carried out for the members. After that transportation of members to the site and the process of erection is carried out in a less duration. The performances of these buildings is structurally well understood, to ensure the satisfactory behaviour in high winds for the most part the code provisions are currently in place and adequate. The dismantling process of steel structures is easy because these buildings are connected with the bolts. When compared with strength to weight ratio the steel structures have better ratios than RCC structures. These members can be reused after dismantled.
1.2 Conventional steel building:
1. INTRODUCTION
Steel structures are low rise with the truss system of roofing with roof coverings are termed as conventional steel buildings. For these kind of structures can be utilisation of various types of the roof trusses. According to pitch of truss the type of roof system is used. The steel structures also termed as metal structures. In this construction process producing the shapes of structural steel material used is steel. The shape of steel structure is unique, built with a specific cross section and also including certain chemical composition.

1.3 Pre-Engineered Building and it’s Components:
In all parts of the earth almost steel industry is growing quickly. When there is a situation of resources availability, use of steel structures is economical solution, here word “economical” is used by considering duration and expenditure. The more important aspect in steel structures is time; these are built in very minimum duration of time. For the construction within the short duration, one such method is pre-engineered building construction. These are the buildings consists of steel sections, more amount of steel is avoided by considering the tapered section as per requirement of various analysis. Much more people are not aware of these kinds of structures but someone has to think about its prospect. Regular steel construction requires long
These buildings are the composed with the combination of various sections they are built up sections, hot rolled sections and the elements of cold formed sections. The basic steel frame work is provided by these elements. For roofing and wall cladding with a selection of sheeting of single skin with added insulation or insulated sandwiched panels are provided.
