Investigation on damage evaluation index with ductility factor based on simulation analysis for loading test of piping support structure

Mechanical Engineering Journal
The importance of seismic probabilistic risk assessment has drawn considerable attention for improving the seismic safety of nuclear facilities against earthquakes that exceed the design input ground motion.

New design model of reinforced concrete beams in bending considering the ductility factor

Revista IBRACON de Estruturas e Materiais, 2020
Ductility is a recommended characteristic by different RC structures design codes around the world, such as ABNT NBR 6118 [2], ACI 318 [1] and EUROCODE 2 [4].

Seismic performance evaluation of Egyptian code-designed steel moment resisting frames

HBRC Journal, 2018
Despite the fact that steel is a ductile material, the significant damage, during earthquake events, highlighted the need to thoroughly investigate the seismic performance of steel structures.

Minimum flexural ductility design of high-strength concrete beams [PDF]

, 2004
In the flexural design of reinforced concrete beams, apart from the provision of adequate strength, it is also necessary to provide a certain minimum level of ductility. Traditionally, this has been done by limiting the tension steel ratio or the neutral

Effective linear damping and stiffness coefficients of nonlinear systems for design spectrum based analysis [PDF]

, 2010
A stochastic approach for obtaining reliable estimates of the peak response of nonlinear systems to excitations specified via a design seismic spectrum is proposed. This is achieved in an efficient manner without resorting to numerical integration of the

Selection procedure of seismic-load reduction factor K1 at a given level of ductility factor [PDF]

Инженерно-строительный журнал, 2012
At the present time for providing earthquake resistance of buildings and structures, the multilevel design approach is applied. According to this approach seismic loads corresponding to the level of the maximum design earthquake must be perceived by ...

Effect of glass-fiber rods on the ductile behaviour of reinforced concrete beams

Alexandria Engineering Journal, 2018
Ductility can be defined as the “ability of material to undergo large deformations without rupture before failure”. The use of Glass-fiber reinforced polymer (GFRP) bars instead of steel in reinforcing concrete structures is currently encouraged by many ...

The effect of precipitation on strength and ductility in a Mg-Zn-Y alloy

, 2012
The effect of pre-ageing deformation on the size and distribution of beta-prime precipitates and subsequently on the resulting strength and ductility have been measured in a Mg-3.0at.%Zn-0.5at.%Y alloy.

Assessment of Non-Linear Analyses of RC Buildings Retrofitted with Hysteretic Dampers According to the Italian Building Code

Applied Sciences
While the use of steel hysteretic dampers has spread in the last decade for both new and retrofitted constructions, the Italian Building Code (IBC), as well as the Eurocode 8, does not provide specific recommendations for the design and verification of ...

Near-threshold fatigue crack growth in bulk metallic glass composites [PDF]

, 2009
A major drawback in using bulk metallic glasses (BMGs) as structural materials is their extremely poor fatigue performance. One way to alleviate this problem is through the composite route, in which second phases are introduced into the glass to arrest ...
