Nonlinear seismic response and response reduction factor of building frames on slope

ISET Journal of Earthquake Technology, 2021
The 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.

Evaluation of response reduction factor by pushover analysis

International Journal of Structural Engineering, 2018
Estimation 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 ...

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.

Seismic behavior and response reduction factors for concrete moment-resisting frames

Bulletin of Earthquake Engineering, 2021
The existing seismic provisions across the world account the non-linear response of a structure in a linear elastic design implicitly using a constant behavior factor, or response reduction factor (R). However, this factor (R) does not address the effects of changes in structural configurations, which eventually alters the dynamic behavior of the ...

FACTORS INFLUENCING RESPONSE OF MAMMALIAN SPECIES TO THE METHAEMOGLOBIN REDUCTION TEST

Australian Journal of Experimental Biology and Medical Science, 1966
SummaryFactors 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

Response reduction factor based on geometric variation with soil structure interaction

AIP Conference Proceedings, 2021
The design of structure includes a significant parameter, which is seismic analysis. The earthquake designing for a structure depends on the ductility and strength of frame members. The response reduction value depends on the structure’s ductility and strength, thus contributing to the super structure’s seismic design.

Evaluation of reduction factors for high-damping design response spectra

Bulletin of Earthquake Engineering, 2008
High-damping response spectra are essential tools for the assessment and design methods based on the equivalent elastic structure concept. They are also often used for the analysis and design of structures with seismic isolation or energy dissipation systems. Many formulations of the reduction factors have been proposed and included in seismic codes to

Pathogen Reduction and Factors Responsible for Pathogen Reduction in Dairy Farm Operations Treating Dairy Manure

Biological Engineering Transactions, 2011
Manure management at large dairy operations presents a challenge; there is an increasing interest among farm managers for reuse of their manure and other farm residuals as low-cost bedding materials. A significant barrier preventing more widespread adoption of this technology is ambiguity in regards to the presence of disease-causing agents that may ...

Influential factors responsible for the effect of tax reduction on GDP

Evolutionary and Institutional Economics Review, 2017
The factors responsible for the effect of a tax reduction on GDP are analyzed using both agent-based modeling, based on the authors’ previous study, and a derived set of equations for tax reduction multipliers, based on Morishima’s economic linkage table.

Assessment of Seismic Response Reduction Factor for RC Shaft Supported Tank

Journal of The Institution of Engineers (India): Series A, 2020
The force-based design method as suggested by the major international seismic codes considers the nonlinear behavior through response reduction factor, R, in an indirect way. To obtain the design base shear, the elastic base shear demand is divided by the R factor, assuming adequate ductility and good post-yield behavior of the structural elements ...
