load resistance factor design (LRFD)

Load Resistance Factor Design (LRFD) is an engineering method used to ensure structures like bridges and buildings are safely built. It balances the expected loads (like weight, wind, or snow) with safety factors in the materials and design. By applying specific factors to account for uncertainties and possible variations, LRFD ensures that structures can withstand actual and unforeseen stresses comfortably. It provides a systematic approach to optimize safety and economy, reducing the risk of failure while avoiding overly conservative designs.
