Pre-engineered buildings PEBs are a unique construction methodology that provides structural efficiency, cost savings and fast-track delivery compared to traditional steel and reinforced concrete systems. This survey paper ergs a Literature Based Metanalysis of PEB Structural Analysis Design Optimization with respect to most advanced Computation Software Tools like STAAD Pro This area will not take big measure tools eg ETABS, ANSYS, SAP2000, Tekla Structural Designer Portal frame geometry, tapered section design, portal gable framing, behaviour of eave strut systems, optimal roof slope of freely supported buildings for self-weight or lateral loads resistance (or both), wind load distribution and seismic performance were; the systematic survey carried out among studies published from 2005 to 2024. The review shows that software based design workflows consistently achieve reductions in steel consumption ranging from 15–30 % above the quantities of steel that can be achieved, without significant loss of structural resistance when considering codified load combinations per IS 800, AISC 360 and Eurocode 3. Dynamic soil–structure interaction modelling, lifecycle performance assessment and the integration of Building Information Modelling (BIM) frameworks with structural optimization algorithms are critical gaps. We review issues with methodological inconsistencies across studies and outline standard benchmarking criteria to enhance clarity in future research. A meta-analysis of 30 studies shows a pooled reduction in steel weight of 18.6% (95% CI : 14.2–23.0%) with high between-study heterogeneity (I² = 74.3%), confirming the vital need for context specific optimization assessment. Results confirm that state-of-the-art software-enabled design may be regarded as the key driver for economical, structure-satisfying PEB systems in industrial, commercial and logistic applications. |
