Abstract
Sustainable construction of ecofriendly infrastructure has been the priority of worldwide researchers. The induction of modern technology in the steel manufacturing industry has enabled designers to get the desired control over the steel section shapes and profiles resulting in efficient use of construction material and manufacturing energy required to produce these materials. The current research study is focused on the optimization of steel building costs with the use of pre-engineered building construction technology. Construction of conventional steel buildings (CSB) incorporates the use of hot rolled sections, which have uniform cross-section throughout the length. However, pre-engineered steel buildings (PEB) utilize steel sections, which are tailored and profiled based on the required loading effects. In this research study, the performance of PEB steel frames in terms of optimum use of steel sections and its comparison with the conventional steel building is presented in detail. A series of PEB and CSB steel frames is selected and subjected to various loading conditions. Frames were analyzed using Finite Element Based analysis tool and design was performed using American Institute of Steel Construction design specifications. Comparison of the frames has been established in terms of frame weights, lateral displacements (sway) and vertical displacements (deflection) of the frames. The results have clearly indicated that PEB steel frames are not only the most economical solution due to lesser weight of construction but also have shown better performance compared to CSB frames.

The same single span rigid frame was used for both pre-engineered steel buildings (PEB) and conventional steel buildings (CSB)
Summary
Apart from making the steel building economical in terms of cost, time and quality, experts are working on making those steel buildings environmentally friendly and green throughout its life-cycle [1,4,5,6]. 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 [3,7]. Pre-engineered steel buildings prove to be very economical and environmentally friendly as compared to conventional steel frames [5,7]. Once the design life is over, most of the pre-engineered steel buildings end up at a recycling center where they are melted and Suussetadinafboilrityth20e18o, t1h0,exrFpOuRrPpEoERseRsEVraIEtWher than being dumped at the local available land/grou2nodf ,16thus reducing construction and demolition waste [8].
