Comparative Study of Pre-Engineered and Conventional Steel Structures with Crane Load

Industrial buildings are generally constructed using either Pre-Engineered Building (PEB) systems or Conventional Steel Building (CSB) systems depending on design requirements and economy. Although both systems are commonly used, their behavior changes when crane loads are included, because crane loads add extra vertical and horizontal forces that affect member design and total steel requirement. In this study, a comparative analysis of PEB and CSB industrial structures with crane loading has been carried out using STAAD.Pro software by adopting identical geometric configurations and relevant load combinations including dead load, live load, wind load, seismic load and crane load as per Indian Standard provisions. The main aim of this study is to compare the steel tonnage of the two structural systems and to examine their displacement and internal force behavior. The results show a clear difference in steel usage and force distribution between PEB and CSB. The PEB system uses steel more efficiently because of its optimized and tapered sections
