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 ...

Evaluation of Link Overstrength Factor for the Seismic Design of Eccentrically Braced Frames

Applied Sciences
In 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

Predictive modelling and latent space exploration of steel profile overstrength factors using multi‐head autoencoder‐regressors

ce/papers, 2023
AbstractThis paper investigates the suitability and interpretability of a data‐driven deep learning algorithm for multi cross sectional overstrength factor prediction. For this purpose, we first compile datasets consisting of experiments from literature on the overstrength factor of circular, rectangular and square hollow sections as well as I‐ and H ...

Evaluation and suggestions for improvement of seismic design procedures for R/C walls in dual systems [PDF]

, 2010
This paper aims to shed some further light on the seismic behaviour and design of reinforced concrete (R/C) walls which form part of dual (frame + wall) structures.

Overstrength Factors of Buckling Restrained Braced Frames [PDF]

Journal of the Earthquake Engineering Society of Korea, 2004
In this study the overstrength factors of medium to low-rise bucking restrained braced frames (BRBF) were evaluated. Various design variables, such as number of stories, span length, yield strength of the brace, level of earthquake load, and the response modification factors.

Overstrength factors of RC bridges supported on single and multi‐column RC piers in Mexico

Earthquake Engineering & 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,

Effect of irregularity on seismic design parameters of RC-infilled structures

Magazine of Civil Engineering, 2021
A four-storey reinforced concrete (RC) building is seismically evaluated with the incorporation of different irregularities. Three model systems have been considered, i.e., model I: (RC-infilled regular frame in X and Y direction), model II: (RC-infilled

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

Response Modification Factor of RC Frames Strengthened with RC Haunches

Shock and Vibration, 2020
This paper presents experimental and numerical studies carried out on two-story reinforced concrete (RC) frames having weaker beam-column joints, which were retrofitted with reinforced concrete haunches to avoid joint panel damage under seismic actions ...
