Evaluation of response reduction factor and ductility factorfor RC braced frame [PDF]
Journal of Materials and Engineering Structures, 2015 Response reduction factor is the factor by which the actual base shear force should be reduced, to obtain the design lateral force during design basic earthquake (DBE) shaking. The response reduction factor (R) is basically depends on Over strength (Rs),

Ductility and Strength Reduction Factors for Degrading Structures Considering Cumulative Damage [PDF]
The Scientific World Journal, 2014 The effect of cumulative damage on the strength requirements of degrading structures is assessed through the evaluation of the target ductility and corresponding strength reduction factors of simple degrading structures. While the reduction on ductility is established through the use of Park and Ang index, the suggestions given by Bojórquez and Rivera ...
