Abstract In ACI 318-11 and ASCE/SEI 7-10 an overstrength factor, Ω 0 , was introduced for the seismic design of nonstructural building component anchorage into concrete. Though implemented into these codes with the same mechanisms as the overstrength factor for building structures, the rationale behind its inclusion for anchorage was fundamentally ...

AIP Conference Proceedings, 2019 In this paper, an empirical relation to compute an overstrength factor for Theory of Plastic Mechanism Control (TPMC) has been presented. This regression, accounting for random material variability, has been obtained as function of number of storeys, number of bays, coefficient of variation and the probability of failure of TPMC, provided by 25 Moment ...

Overstrength of dowelled CLT connections under monotonic and cyclic loading
Bulletin of Earthquake Engineering, 2017 This paper presents an evaluation of overstrength based on an experimental study on dowelled connections in Cross Laminated Timber (CLT). Connection overstrength needs to be well understood in order to ensure that ductile system behaviour and energy ...

Overstrength factor of short low-yield-point steel shear links
Thin-Walled Structures, 2021Abstract Owing to the relative uncertainty of previous numerical and experimental studies on the behavior of short and very short shear links, this article considers the overstrength factor of short and very short low-yield-point (LYP) steel shear links with or without stiffeners.

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,

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.

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 ...

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.

Earthquake Engineering and Structural Dynamics, 2015 This paper investigates the effect of the gravity framing system on the overstrength and collapse risk of steel frame buildings with perimeter special moment frames (SMFs) designed in North America. A nonlinear analytical model that simulates the pinched

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
