Compressive Behavior of Circular Concrete Columns Confined

FRPConfinedConcrete - OpenSeesWiki

Mar 08,  · Example: Cantilever FRP-Confined Circular Reinforced Concrete Column under Cyclic Lateral Loading Cantilever Column Model Definition. The cantilever column was modeled by a linear beam element with its stiffness corresponding to flexural yielding and by a fiber element at the plastic hinge which is used in order to capture the flexural

Compressive behavior of concrete columns confined with

An experimental and analytical study on the compressive behavior of plain concrete confined by a new class of composite materials originated from basalt rock, Basalt Fiber Reinforced Polym er (BFRP) is discussed in this thesis . The main objective of this study is to observe the difference between compressive behavior of circular and

Axial load behavior of circular and square concrete

Apr 06,  · It is found that none of the existing models is capable of accurately predicting the strength of concrete confined with SFRP. Finally, new strength models based on a linear relationship between confined concrete compressive strength and lateral confining pressure are proposed to predict the compressive strength of circular and square sections.

Behaviour of Rubberized Concrete Short Columns Confined by

Feb 20,  · The short columns were confined using AFRP jacket. The confinement was carried out to (a) restore the initial compressive strength of concrete [] and (b) prevent the occurrence of the shear failure in the short columns [] when the RC model was subjected to various loading scenarios [].Given the limited number of papers related to structural applications of RuC, the findings of the research

ANN Model for Predicting the Compressive Strength of

Oct 11,  · The compressive strength of concrete is considerably increased by the lateral confined steel tube in circular concrete filled steel tube (CCFT). The aim of this study is to present an integrated approach for predicting the steel-confined compressive strength of concrete in CCFT columns under axial loading based on large number of experimental

Axial compressive behavior of bamboo slices twining tube

A total of 10 BST and BST-confined concrete (BCC) short columns were subjected to axial compressive tests using the BST wall thickness as a variable. The test results show that the mechanical properties of BSTs are close to those of engineered bamboo under tension and compression. The failure mode of the BCC specimens is the rupture of the BST

COMPRESSIVE PERFORMANCES OF THE CONCRETE FILLED CIRCULAR

Jul 25,  · A constitutive relationship suitable for concrete confined by circular CFRP-steel composite tube was proposed, and a finite element model was established by using ABAQUS for analyzing load-deformation relationship of the composite stub columns and it shows that the results predicted check well with that of the test and were on the safe side.

Modified Numerical Modeling of Axially Loaded Concrete

Predicting the behavior of concrete in a Concrete-Filled Steel Tubular (CFST) column is challenging due to the sensitivity to input parameters such as the size of the cross-section, the material modeling, and the boundary conditions. The present paper proposes a new modified finite element model to predict the behavior and strength of a CFST subjected to axial compression.
