Assessment of Spectrum Modification Factor for Design of Steel Moment Frames in Near Fault Regions [PDF]
Journal of Structural and Construction Engineering, 2018 Iranian Seismic design code (standard No. 2800) increases the design spectrum ordinates by a modification factor (N factor), to consider the damaging effects of near fault ground motions in design procedure of structures.

The Effect of Spandrel Beam's Specification on Response Modification Factor of Concrete Coupled Shear Walls [PDF]
Civil Engineering Infrastructures Journal, 2016 Response modification factor (R factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. This paper has tried to evaluate the response modification factor of concrete coupled shear

Evaluation Of Response Modification Factor For Moment Resisting Frames
Kalpa Publications in Civil Engineering, 2018 Conventional seismic analysis of structure incorporates only elastic response of the structure. To understand nonlinear response of the structure, Performance Based Design (PBD) approach is widely used. PBD includes Pushover analysis i.e. nonlinear static analysis, which shows the post-elastic behaviour of the structure.

Journal of Asian Architecture and Building Engineering, 2022 A K-shaped eccentrically braced high-strength steel frame is a novel structure. For such structures to exhibit good plastic deformation under severe earthquakes, the links are made of ordinary steel (fy≤345 MPa), whereas high-strength steel (fy≥460 MPa ...

Evaluating response modification factor (R) for some types of steel structure
Ingeniería e Investigación, 2008 Response modification factor (R), tabulated in the Colombian Design Code as NSR-98, is used in this paper for eva-luating internal member forces produced by design earthquake action on steel structures and the inconsistencies pre-sent when designing ...

Determination of response modification coefficient of Steel Plate Shear Walls in Reinforced Concrete Frame using performance-based plastic design method [PDF]
Journal of Structural and Construction Engineering, 2021 In the last few decades, the idea of using thin steel plate shear wall, ( SPSW ) , has been noted as a lateral load resisting system in design and retrofit of buildings.
