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 ...

Feeding overstrength cows' milk to babies. [PDF]
Br Med J, 1974 The dangers of overstrength milk feeds have been emphasized in several reports during the last two years. They may even be a factor in unexpected death in infants. Samples of prepared dried milk feeds were obtained from 302 mothers who brought their 5- to 8-week-old infants to a special follow-up clinic.

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 ...

Simulation model to estimate bending overstrength in concrete elements
Dyna, 2017 A simulation model to estimate bending overstrength in reinforced concrete elements is presented. The simulation model employs basic design hypotheses according to NTC–04 [1] and ACI 318–11 [2] for rectangular concrete beams subjected to bending with ...

Ductility and overstrength of nailed CLT hold-down connections
Engineering Structures, 2020 Abstract The structural performance of nailed hold-down connection systems used for cross-laminated timber (CLT) shear walls under monotonic and cyclic loading was experimentally evaluated. Critical connection performance parameters, including strength, stiffness, ductility, and overstrength, were derived from the testing of 68 hold-down connection ...

Ductility and overstrength of shape-memory-alloy reinforced-concrete shear walls
Engineering Structures, 2021 Abstract The unique properties of superelastic shape-memory-alloy (SMA) bars have motivated researchers to investigate their use as reinforcing bars for concrete elements. They were found to decrease seismic residual deformations, while increasing seismic inelastic deformations.

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

Overstrength of Displacement-Based Designed Eccentrically Braced Steel Frames [PDF]
Journal of Structural and Construction Engineering, 2016 Direct Displacement-Based Design (DDBD) is a performance-based seismic design method that has been proposed and developed over the past two decades for RC frame structures, shear walls and bridges design. The aim of this study is to evaluate overstrength

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 ...
