Modeling flexural overstrength factor for steel beams using heuristic soft-computing methods
Structures, 2021Abstract When evaluating the structural performance of steel moment-resisting frames, significant consideration is given to the flexural behavior of steel beams. This analysis focuses on the primary response parameters, such as the ultimate flexural resistance and rotation capacity that dictate the behavior of the steel beam.

Reliability-based overstrength factors of cross-laminated timber shear walls for seismic design
Engineering Structures, 2021Abstract The ductile collapse mechanisms of structures should be less resistant than the brittle mechanisms to ensure a ductile seismic response: in this way, the ductile mechanisms activate before the brittle ones. This sort of chronological law of collapse is obtained in the design phase by providing a proper ”overstrength” to the brittle ...

Overstrength and force reduction factors of multistorey reinforced‐concrete buildings
The Structural Design of Tall Buildings, 2002AbstractThis paper addresses the issue of horizontal overstrength in modern code‐designed reinforced‐concrete (RC) buildings. The relationship between the lateral capacity, the design force reduction factor, the ductility level and the overstrength factor are investigated.

Evaluation of overstrength factor of short links in the eccentrically braced frames (EBFs)
AIP Conference Proceedings, 2022The aim of this work is the evaluation of the overstrength factor of short links of eccentrically braced frames. Starting from the experimental tests provided by the scientific literature, after the collection and the cataloging of experimental data, the author identified the main geometrical and mechanical parameters influencing the overstrength of ...

Overstrength factors for SDOF and MDOF systems with soil structure interaction
Earthquakes and Structures, 2016This paper addresses the concept of lateral overstrength; the ratio of actual lateral strength to design base shear force, for both SDOF and MDOF systems considering soil structure interaction. Overstrength factors are obtained with inelastic time history analysis for SDOF systems for period range of 0.1-3.0 s, five different aspect ratios (h/r=1, 2, 3,

Determining the overstrength factor based on statistical values of European steel grades
Steel Construction, 2020AbstractIn dissipative seismic design concepts, capacity design rules must be applied to control the plastic mechanism. For this purpose, nondissipative structural elements require an overstrength with respect to dissipative zones. The scattering of the yield strength of structural steel is considered in DIN EN 1998‐1 by the material overstrength ...

Overstrength and Ductility Factors for Steel Frames Designed According to BS 5950
Journal of Structural Engineering, 2003Buildings sited outside the seismic zones such as those in Singapore are not designed for seismic loads. However, the buildings in these regions vibrate due to tremors caused by faults in Sumatra, Indonesia. Therefore, in order to assess the vulnerability of these buildings under low-seismic excitation, it is important to determine the overstrength and

Prediction of the flexural overstrength factor for steel beams using artificial neural network
Steel and Composite Structures, 2014The 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

Evaluation of behaviour factors on the basis of ductility and overstrength studies
Engineering Structures, 1999The paper focuses on the evaluation of behaviour factors for seismic design of structures, with due consideration to both their ductility and overstrength. Firstly, inelastic strength spectra for typical target ductilities are presented for earthquake motions representative of those expected in Southern Europe, in particular Greece, the country with ...

Influence of the link overstrength factor on the seismic behaviour of eccentrically braced frames
Journal of Constructional Steel Research, 2007Abstract The paper investigates the influence of the link overstrength factor on the seismic behaviour of eccentrically braced frames designed in accordance with capacity design principles. To this end, systems characterised by different level number and link length are designed according to the force-based approach, by either static or modal ...
