Effect of load cycling on plastic hinge length in RC columns

Engineering Structures, 2017
Due to the high complexity of the plastic hinge in reinforced concrete (RC) columns, investigation of its behavior under cyclic loading has largely been studied by experimental testing. However, different experimental works reported in the literature have focused on a certain aspect or special cases only, due to the high cost of testing.

Plastic hinge length of circular reinforced concrete columns

Computers and Concrete, 2012
This paper presents a parametric study of the plastic hinge length of circular reinforced concrete columns using a three-dimensional finite element analysis method, and using the Taguchi robust design method to reduce computational cost. Parameters examined include the longitudinal reinforcing ratio, the shear span-to-depth ratio, the axial force ratio

Plastic Hinge Length of FRP-Confined Square RC Columns

Journal of Composites for Construction, 2014
The confinement effect of fiber-reinforced polymer (FRP) jacket on the plastic hinge length of square RC columns is studied through experimental testing and analytical study. Seven half-scale RC square columns with different confinement ratios were tested.

Plastic Hinge Length of Reinforced Concrete Columns

ACI Structural Journal, 2008
Severe damage can be observed in regions subjected to large moments when a column experiences earthquake-induced lateral displacements while supporting gravity loads. These regions, which experience large inelastic curvatures, are referred to as plastic hinges.

Plastic hinge length of reinforced concrete slender shear walls

Magazine of Concrete Research, 2015
This paper proposes a simple model that can reasonably determine the potential plastic hinge region for seismic design of shear walls. To idealise the plastic hinge region, a parametric study is conducted on the curvature distribution over the member length using a non-linear, two-dimensional, finite-element analysis procedure.

Evaluation of the Plastic Hinge Length for Nonlinear Analysis of Reinforced Concrete Buildings

2015
Pushover analysis is among the most popular of approaches for the seismic assessment of reinforced concrete (RC) structures. In lumped-plasticity structural models, the underlying idea is to approximate the global inelastic behaviour by means of the formation of localized plastic hinges at the frame elements’ ends throughout the incremental nonlinear ...

DETERMINING PLASTIC HINGE LENGTH OF HIGH PERFORMANCE RC BEAMS

2017
Duringearthquake concrete structures dissipate energy by deforming inelastically. Theplastic deformation localized in a small zone namely the plastic hinge zone iscritical for flexural members as it governs the load carrying and deformationcapacities of the member.
