This document discusses the study of different bracing patterns used in pre-engineering buildings. It analyzes the harp, perimetral, and peripheral bracing patterns through 3D modeling and structural analysis software. The harp pattern directly controls column displacement through tensile beams. The perimetral pattern connects panels to control deflections and forces. The peripheral pattern minimizes deflections at eave ends. Analysis of the models found that the perimetral pattern most effectively controls lateral and longitudinal loads and is the most economical in terms of steel consumption.
