Steel Ductile Detailing of Moment Resisting Frames for Pre-engineered Buildings

Abstract

Long span structures with no interrupting column are necessary in any type of industrial structures and pre-engineered buildings (PEB) satisfies this need along with less time and cost as compared to conventional structures. This methodology is adaptable not only due to its quality pre-designing and prefabrication, but also due to its light weight and economical construction. The concept includes the technique of providing the best possible section according to the optimum requirement. This concept has many advantages over the conventional steel building (CSB) with roof truss. Although PEB systems are extensively used in industrial and many other non-residential constructions worldwide, it is relatively a new concept in India.The present work involves the static analysis and design of pre-engineered building moment resisting steel frames. A study has been undertaken to evaluate the similarities and differences between the Pre-Engineered steel building design specifications for seismic forces used in the India and United States. This study includes the seismic ductile detailing of beam-column joints of a steel moment frame by using limit state method (IS 800: 2007) and IS 1893: 2002 (part 1) and the gap in IS 800: 2007 is fulfilled using American Code AISC 360-10 (2010) and AISC 341-10 (2010).
