Strength Reduction Factor/ Resistance / Partial Safety Factors
|
|
|
Enter the strength reduction 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; uncertainties related to inaccuracies in the design equations; and the ductility and importance of the member. |

Design CodeDisplay the selected design code. Update By Code: Factors are automatically changed to the values specified in the selected design code.
Strength Reduction FactorsEnter the strength reduction factor in each field. For Flexure (Phi_B): Strength reduction factor for pure flexure or flexure + axial tension For Axial Tension (Phi_T): Strength reduction factor for axial tension For Axial Compression, and Axial Compression and Bending - Spirally Reinforced Column (Phi_C1): Strength reduction factor for spirally reinforced columns subjected to axial compression or flexure + axial compression - Other Reinforced (Tied) Column (Phi_C2): Strength reduction factor for tied columns subjected to axial compression or flexure + axial compression For Shear (Phi_V): Strength reduction factor for shear Note
Design Resistance Factors It is available when BS5950 design code is selected. Strength of the Material (Gamma m1) Manufacturing Tolerances (Gamma m2)
Partial Safety Factors It is available when Eurocode3, IS:800 or IRC:24-2010 design code is selected. Class 1, 2, or 3 Cross-Section (Gamma m0) Class 4 Cross-Section (gamma m1) Net Section at Bolt Holes (Gamma m2)
