Strength Reduction/Design Resistance/Partial Safety Factors

Function

  • Enter the strength reduction / Design Resistance / Partial Safety factors, which are a form of safety factors to account for the difference between the nominal and real strengths of the materials; the difference in member strengths between the design and manufacturing or construction; and uncertainties related to inaccuracies in the design equations.
