Response reduction factor of irregular RC buildings in Kathmandu valley
Earthquake Engineering and Engineering Vibration, 2014 Most current seismic design includes the nonlinear response of a structure through a response reduction factor (R). This allows the designer to use a linear elastic force-based approach while accounting for nonlinear behavior and deformation limits.

Performance-based evaluation of the response reduction factor for ductile RC frames
Engineering Structures, 2013 Abstract Most seismic design codes today include the nonlinear response of a structure implicitly through a ‘response reduction/modification factor’ ( R ). This factor allows a designer to use a linear elastic force-based design while accounting for nonlinear behaviour and deformation limits.

Advances in Structural Engineering, 2020 Bouncing is a typical rhythmic crowd activity in entertaining venues, such as concert halls and stadia. When the activity’s frequency is close to the natural frequency of the occupied structure, the corresponding bouncing loads can cause intense structural vibrations resulting in vibration serviceability problems, even structural damage.

Nonlinear seismic response and response reduction factor of building frames on slope
ISET Journal of Earthquake Technology, 2021The response reduction factor (R) is used in seismic design to account for nonlinear response of structures. Significant research efforts have been made to obtain R factor for buildings. Various national codes recommend R values depending on structural configurations and construction details mainly for buildings on flat grounds.

Response Reduction Factor of Steel – RC Hybrid Structure
KEC Journal of Science and Engineering, 2023Civil Engineering structures should have sufficient strength and stiffness to control deflection and prevent possible collapse of the structure during a seismic event. The design force levels currently specified by most seismic codes are calculated by dividing the base shear for elastic response by the response modification factor (R).

Evaluation of response reduction factor by pushover analysis
International Journal of Structural Engineering, 2018Estimation of seismic forces plays a vital role in the design of the structure and generally these forces are computed using the linear static method with aid of response reduction factor. Response reduction/modification factor (R) incorporates the nonlinear response of any structure during a seismic event, allowing the designer for a linear force ...

FACTORS INFLUENCING RESPONSE OF MAMMALIAN SPECIES TO THE METHAEMOGLOBIN REDUCTION TEST
Australian Journal of Experimental Biology and Medical Science, 1966SummaryFactors influencing variations observed with mammalian species in response to the methaemoglobin reduction test have been investigated by extending the test to include measurements of the stability of “intact” haemoglobin (methaemoglobin plus oxyhaemoglobin) and of the stability of reduced glutathione, by modifying the conditions of the test and

Improved damping reduction factor models for different response spectra
Engineering Structures, 2021Abstract The rationality and reliability of the damping reduction factor are of great significance to the seismic design of building structures. However, the values of damping reduction factor predicted by the existing models have great dispersions, which are mainly related to the regression model and the considered influencing factors.
