Overstrength factors of RC bridges supported on single and multi‐column RC piers in Mexico [PDF]
Earthquake Engineering and Structural Dynamics, 2021 Mexico 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 ...

An Evaluation of Overstrength Factor of Seismic Designed Low Rise RC Buildings
Procedia Engineering, 2013 This 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

A Novel Statistical Model for Link Overstrength
, 2014 The Eccentrically Braced Frame (EBF) has both high ductility and high stiffness characteristics. The key member of the EBF is the link, which acts as a sacrificial fuse by dissipating seismic energy.

Overstrength of RC Medium Length Span Bridges
Applied Mechanics and Materials, 2022Overstrength factors in bridges reported in various studies show great diversity that depends on the type of bridges selected and the set of seismic records used in the analyses. Particularly in Mexico, there are no previous studies that evaluate the bridges’ overstrength.

Seismic Overstrength in Reinforced Concrete Frames
Journal of Structural Engineering, 1995Seismic overstrength of multistory reinforced concrete frames has been assessed by means of nonlinear pseudostatic analysis on four-bay, three-, six-, and nine-story frames designed for seismic zones I to V as per Indian codes. In pseudostatic analysis, the lateral force profile corresponding to the first mode of elastic vibration is applied ...

STUDY ON THE OVERSTRENGTH OF HEA EBFS LINKS BY FEM SIMULATIONS
, 2019 In this paper, numerical analyses of detailed finite element models (FEM) have been carried out to verify the combined influence of link length, boundary conditions and stiffener spacing on the plastic overstrength of “I shaped” HEA links for eccentrically braced frames. Parametric analysis has been carried out by means of FEM simulations under cycling

Brittle failure in RC masonry infilled frames: The role of infill overstrength [PDF]
Engineering Structures, 2018 The interaction between an infill panel and a reinforced concrete (RC) column can lead to the brittle failure of the structural element. A novel combination of cutting-edge analytical modelling approaches for masonry infills and RC elements is employed ...

Connection overstrength in steel-braced RC frames
Engineering Structures, 2008Steel bracing systems can be used effectively for seismic retrofitting of existing RC buildings as well as for seismic design of new buildings. Although adaptation of bracing to upgrade the lateral load capacity of existing RC frames has been the subject of a number of successful studies, guidelines for its use in newly constructed RC frames need to be
