  An experimental program has been made in order to study the confined concrete behavior when its strength changes from traditional values to high strength values and with confinement levels ranging from 0% to values higher than 4%. The specimen shape and size have also been included as variables. With the data experimentally achieved, the parameters that define the stress-strain curve Cited by: 3. The behaviour of concrete columns with interlocking spirals The behaviour of concrete columns with interlocking spirals Kim, Jin-Keun; Park, Chan-Kyu The objective of this study is experimentally to investigate the strength and the deformability of specimens with interlocking spirals subjected to concentric axial loads.

Behaviour of reinforced concrete columns confined with circular spirals and hoops by Murat TugпёЈrul Toklucu Download PDF EPUB FB2

Transverse reinforcement is increased; and (5) spirals or circular hoops are used instead of rectangular hoops and supplementary cross ties [4–26]. Cusson and Paultre [6] have tested twenty seven square concrete columns to investigate the behavior of large-scale high-strength concrete columns confined by rectangular ties under axial.

One of the best alternatives to steel bars is carbon fibre-reinforced polymer (CFRP) bars. The experimental program consisted of 18 reinforced rectangular concrete columns under different eccentric : Zrar Sedeeq Othman, Ahmed Heidayet Mohammad.

RC columns with two layers of hoops is a new kind of column recently proposed. The concrete of the column is under three different degrees of confinement, namely unconfined concrete cover, singly-confined concrete between the two layers of hoops and doubly-confined concrete inside the inner layer of hoops.

The strength and ductility of the column can be greatly enhanced due to Cited by: 5. The writers investigated the axial load behavior of 10 spirally reinforced concrete columns.

Six of the mm diameter columns were confined with a GFRP spiral and four were confined with a steel spiral. Some of the columns that were confined with a GFRP spiral utilized steel vertical bars (hybrid columns), whereas others utilized GFRP vertical bars (all-GFRP columns).

The stress-strain and load-displacement behavior. In this paper, axial compressive behavior of concrete columns confined with CFRP strip ties was evaluated and compared with the columns confined with steel and pultruded CFRP by: 1. Twenty-seven short concrete columns reinforced with longitudinal steel and circular spirals or hoops were tested to failure under monotonic axial compression.

Effects of different variables, such as amount and type of lateral steel, lateral steel spacing, and specimen size, on the behavior of columns were investigated. GFRP and steel bars exhibit the same behaviour for confined circular columns concrete cores. The ductility and load-carrying capacity of GFRP-reinforced columns is increased by the reduction in the ligature spacing, whereas the axial-load carrying capacity is decreased compared to that of the steel RC column.

Twenty-seven short concrete columns reinforced with longitudinal steel and circular spirals or hoops were tested to failure under monotonic axial compression.

Although fiber reinforced polymer (FRP) confined concrete columns have been extensively investigated, a satisfactory stress–strain model for the columns under eccentric loading has not been. REINFORCED CONCRETE COLUMNS CONFINED BY CIRCULAR SPIRALS AND HOOPS.

Nonetheless, the axial compression behavior of FRP reinforced concrete (RC) columns has not yet been defined. This study introduces equations and a confinement model to predict the stress-strain envelope responses of RC columns reinforced with carbon-FRP bars (CFRP) and confined by CFRP spirals or hoops.

The relation between lateral pressure on concrete and concrete strength enhancement and the variation of spiral. To improve the mechanical behaviour of reinforced concrete (RC) columns with square cross-section, an additional configuration of transverse reinforcement using high-strength multiple-tied spirals is proposed to achieve better lateral confinement to the concrete and to delay or avoid the buckling of longitudinal by: 3.This study deals with a series of tests on circular and square plain concrete (PC) and reinforced concrete (RC) columns strengthened with carbon fiber reinforced polymer (CFRP) sheets.

According to the obtained test results, FRP-confined specimens’ failure occurs before the FRP reached their ultimate strain by: 7.
