An Evaluation of Overstrength Factor of Seismic Designed Low Rise RC Buildings
Procedia Engineering, 2013 AbstractThis study investigates the overstrength factor of reinforced concrete frame designed according to EC2 and EC8. There are two families of building considered in this study, i.e: regular and irregular in elevation with setback. Each family are designed to gravity load only and designed to resist seismic load with medium ductility and high ...

Overstrength factors of RC bridges supported on single and multi‐column RC piers in Mexico [PDF]
Earthquake Engineering and Structural Dynamics, 2021 AbstractMexico highway network has more than 14,000 bridges. Most of them are reinforced concrete (RC) structures. The bridges design process incorporates the use of an overstrength factor that is not justified and has received little attention in published works. Mexican regulations allow using an overstrength factor for buildings in the range of 2–3,

A novel formulation of the flexural overstrength factor for steel beams [PDF]
Journal of Constructional Steel Research, 2013 Abstract The ductile design of steel structures is directly influenced by the flexural behaviour of steel beams, which should be sufficient to allow plastic hinges to rotate until the collapse mechanism is completely developed. To guarantee the achievement of such a performance, the beam flexural overstrength must be quantified to appropriately apply

Evaluation of Link Overstrength Factor for the Seismic Design of Eccentrically Braced Frames
Applied SciencesIn eccentrically braced frames (EBFs), inelastic behavior is only permitted in the links. All members, except for the links, are designed according to the capacity design concept by using the link overstrength factor, Ω, so that they remain elastic even ...

Effect of Building Configuration on Overstrength Factor and Ductility Factor
, 2021 It is important for the structure to be economical and still have a high level of life safety. The lateral force sustained by the structures during a large earthquake would be several times larger than the lateral force for which the structures are designed. This is opposite to the fact that design loads such as gravity in codes are usually higher than

Overstrength and ductility factors of XBF structures with pinned and fixed supports
Studia Geotechnica et Mechanica, 2023 In today's time, most seismic design codes are based on a linear elastic force-based approach that includes the nonlinear response (ductility and overstrength) of the structure through a reduction factor (named behavior factor q in Eurocode 8 [EC8 ...

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

Investigating effects of boundary conditions on the evaluation of R-factor of un-braced steel frames
HBRC Journal, 2017 Design of Structures to resist seismic load depends on the theory of dissipation in elastic of energy that already exists in response modification factor “R-factor”.

Prediction of the flexural overstrength factor for steel beams using artificial neural network
Steel and Composite Structures, 2014 The flexural behaviour of steel beams significantly affects the structural performance of the steel frame structures. In particular, the flexural overstrength (namely the ratio between the maximum bending moment and the plastic bending strength) that steel beams may experience is the key parameter affecting the seismic design of non-dissipative members

Earthquake source effect and impact of the applied methodology to assess the overstrength factors of RC bridges [PDF]
Soil Dynamics and Earthquake Engineering, 2022 Seismic hazard assessment in several sites worldwide depends on two or more seismic sources. Many countries affected by subduction zones have strong motions earthquakes originated in at least two important seismic sources. In Mexico, interplate earthquakes (subduction process) have epicenters located in the Pacific coast with hypocenter depths less ...
