LRFD

LRFD stands for Load and Resistance Factor Design. It is an engineering method used primarily in the design of structures like buildings and bridges. LRFD accounts for different types of loads a structure may face, such as weight, pressure, and environmental factors, and applies safety factors to both loads and the materials' resistance to those loads. This approach ensures that structures are safe and reliable by balancing potential risks and uncertainties, leading to more efficient designs that can withstand real-world conditions while using materials effectively.
