Effect of Infills on the Response Modification Factor for Infilled Reinforced Concrete Frame Buildings [PDF]

, 2023
RC frames with unreinforced masonry infill walls are the most common type of building. Unreinforced masonry walls are often not considered by engineers in the design process, although walls and frames interact during strong ground motion, leading to ...

RESEARCH INTO THE DEVELOPMENT OF A RESPONSE MODIFICATION FACTOR FOR DIAGRID STRUCTURES

Proceedings of International Structural Engineering and Construction, 2021
The diagrid structure system has recently gained popularity as an effective structural system for high rise buildings. The effectiveness of the system relies on the truss action developed by the perimeter diagrid system to resist lateral loads. In active seismic zones, ductile performance of the lateral resisting system is highly desired to dissipate ...

Response modification factor - Review paper

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Response modification factor (R) has a main function in the seismic design of new construction materials and is a seismic design parameter in equivalent static analysis. It determines the nonlinear performance of building structures during strong earthquakes.
