Load and Resistance Factor Design (LRFD)
Load and Resistance Factor Design (LRFD) is a method used in engineering to ensure structures, like buildings and bridges, are safe and reliable. It combines two main ideas: estimating the loads (forces like weight and wind) that a structure might face and evaluating the material's resistance to those loads. By applying different safety factors to both the loads and the resistance, engineers create a balanced design that accounts for uncertainties. This approach helps minimize the risk of failure, improving safety while optimizing material use and cost.

Load and Resistance Factor Design (LRFD) is an engineering approach used to ensure structures, like bridges and buildings, are safe and reliable. It combines different factors to account for uncertainties in both the loads a structure will experience (like weight, wind, and earthquakes) and the strength of the materials used. By applying specific safety factors to both loads and resistance, engineers create a balanced design that reduces the risk of failure while optimizing material use. This method helps to ensure that structures can safely support their intended loads throughout their lifespan.
