Effect of Ductility Level on the Seismic Behavior of Low Reinforced Concrete Moment-Resisting Frames Equipped by Double Friction Pendulum Bearings Isolation [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
The base isolation method is being utilized for more than two decades as a way to protect structures. Despite recent advancements in the seismic evaluation of isolated structures, the impact of ductility level on based-isolated Reinforced Concrete (RC ...

Interaction of piled foundation with a rupturing normal fault [PDF]

open access: yes, 2013
Post-seismic observations in the 1999 Kocaeli earthquake in Turkey have indicated that piled foundations may be less suitable than stiff mat foundations in defending a structure against a major normal fault rupturing underneath.

Hot ductility of TiNb IF steel slab after hot torsion testing [PDF]

open access: yes, 2019
The aim of the work was to evaluate the hot ductility loss in TiNb stabilized IF steel directly from the continuously-cast slab using hot torsion testing (plastometry) in the temperature range 600-1250 degrees C according to the basic programme, and also

Perforated steel block of realizing large ductility under compression: Parametric study and stress–strain modeling

open access: yesReviews on Advanced Materials Science, 2022
On one hand, the nature of linear elastic up to brittle rupture hinders the application of fiber-reinforced polymer (FRP) bars as reinforcement in the concrete member due to the displacement ductility demand of structures. On the other hand, FRP bars are

Ductility demand for uni-directional and reversing plastic hinges in ductile moment resisting frames

open access: yesBulletin of the New Zealand Society for Earthquake Engineering, 1999
In a major earthquake the beams in moment resisting frames may develop either reversing or unidirectional plastic hinges. The form of plastic hinge depends upon the ratio of the moments induced by the gravity loading to those induced by the seismic actions.
