In the LRFD method of design, why are the load factors for live loads a larger number than those for dead loads?
What will be an ideal response?
Th e load factors used for live loads are larger than those used for dead loads because estimates of weights associated with live loads (which are generally specifi ed by building codes in pounds per square foot) are less accurate than the estimates used for gravity dead loads, and so the larger load factors address the risk of underestimating the actual weights.
