Overstrength of I-Shaped Shear Links for EBF Design

Engineering Journal, 2023
Past experimental research on EBF indicated that the link overstrength, particularly that for short (i.e., shear) links, could be much higher than that specified in the AISC Seismic Provisions, thus potentially leading to an unsafe design of beams, columns, and gusset connections per the capacity design requirements.

Uncertainly Analysis of Flexural Overstrength for Capacity Design of RC Beams

Journal of Structural Engineering, 2014
AbstractTo ensure an overall ductile structural behavior, the reinforcing steel used in the seismic design of reinforced concrete (RC) structures is governed by certain specific requirements given in many international codes, such as the Eurocodes and the recently released Italian Building Code (IBC).

Ductility and overstrength in seismic design of reinforced concrete structures

Canadian Journal of Civil Engineering, 1994
The paper first reviews the different approaches taken by codes of practice in their treatment of ductility demand by the use of force modification factors. The way in which structural overstrength affects structural response and the factors influencing overstrength are discussed.

Implications of structural overstrength on the calibration of seismic codes

Bulletin of Earthquake Engineering, 2011
A computer program is developed to test the influence of the structural overstrength to calibrate seismic codes. The program automatically performs an iterative design-evaluation process to calibrate the seismic code. A numerical example is performed in order to test the different approaches. The virtual simulation shows that the force reduction factor

Use of overstrength and inelastic response in seismic design

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2013
Inelastic analysis procedures are more dependable means for predicting the actual seismic response compared with elastic analysis methods. Encouragement to use the former procedures is still limited and designers tend to favour elastic analysis procedures. The permissible reduction in response parameters obtained from elastic analysis unlike those from

Appropriate Overstrength of Shear Reinforcement in Precast Concrete Diaphragms

Journal of Structural Engineering, 2007
Current precast concrete diaphragm design may not necessarily protect the diaphragm from a nonductile shear failure in an overload situation. As evidence exists that diaphragms can attract large inertial loads during strong ground motion, emerging design methodologies are aiming to develop the diaphragm flexural strength.

The role of overstrength on the seismic performance of asymmetric‐plan structures

Earthquake Engineering & Structural Dynamics, 2018
SummaryUneven distribution of seismic demand in asymmetric‐plan structures is a critical concern in earthquake‐resistant design. Contemporary seismic design strategies that are based on linear elastic response, single load reduction factor, and uniform ductility demand throughout an asymmetric system generally lead to unsatisfactory performance in ...

Robustness and overstrength of structures under impacts

2018
Protection and safety of humans are basic needs and have become important issues in the past decades. The ability to address these needs is a multidisciplinary task for which the expertise of various disciplines is required. Engineers, specifically civil engineers, are responsible for the built environment.
