Modification of response reduction factors of overhead water tanks based on ductility factor [PDF]
Discover Applied SciencesAbstractIn the earthquake-resistant design of overhead tanks, this research dealt with the determination of the response reduction factor applicable to overhead water tanks performing beyond the elastic limit. Eight existing water tanks were selected for the investigation and 127 ground accelerations due to 10 Indian earthquakes were selected.

Evaluating the Adequacy of Ductility Requirements of Seismic Design Codes [PDF]
Numerical Methods in Civil EngineeringSeismic design philosophy is based on this principal that destructive earthquakes have a low probability of occurrence, and it is not economical to design structures to perform elastically during such rare events.

Effect of structural characteristics distribution on strength demand and ductility reduction factor of MDOF systems considering soil-structure interaction [PDF]
Earthquake Engineering and Engineering Vibration, 2012 It is known that structural stiffness and strength distributions have an important role in the seismic response of buildings. The effect of using different code-specified lateral load patterns on the seismic performance of fixed-base buildings has been investigated by researchers during the past two decades.

Ain Shams Engineering Journal, 2017 In seismic codes, the force strength reduction factor is proposed to transform elastic to inelastic strength. The ductility reduction factor, Rμ, plays a key role on R factor if no overstrength is present. The Rμ is determined by SDOF systems.

Behaviour Factor of Ductile Code-Designed Reinforced Concrete Frames
Advances in Civil Engineering, 2021 The current generation of seismic design codes is based on a linear elastic force-based approach that includes the nonlinear response of the structure implicitly through a response modification factor (named reduction factor R in American codes or ...

Ductility reduction factor analysis of RC frames considering influences of infilled walls
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The value of ductility reduction factor is directly related to seismic design force. And then it has a vital impact on the safety and economy of structures. Influences of infilled walls as nonstructural members on ductility reduction factor is usual neglected in current codes.
