associated to different limit states. Comparisons with the behavior of previously tested confined masonry walls without openings are also made. The results show that masonry unit type and size of the openings control the behavior and that confined masonry walls, even with large openings, have a significant deformation capacity. They also show

Adelaide Research & Scholarship: Seismic behavior of FRP

The results also indicate that the presence of a concrete filling inside the inner steel tube significantly and positively influences the seismic behavior of DST columns. It is found that the performance of the void-filled DST column is superior to that of a companion CFFT column having identical geometric and

Constitutive Relationship of Concrete Core Confined by

In this paper,the bearing mechanism of square concrete-filled steel tube(CFT) stub column under axial load is analyzed,and a constitutive relationship descri the equivalent single-axis compressive stress of the concrete core confined by square steel tube is put forward based on the typical constitutive model of confined concrete,which takes the restriction of steel tube to concrete as the

Axial load behaviour of concrete-filled steel tubular

This paper reports an experimental study of concrete-filled steel tubular columns. Six short columns subjected to concentric load were tested. Columns of square, circular and rectangular cross-sections with two steel tube thicknesses were considered. The experimental results showed that the ductility of high-strength concrete increases when confined by a steel tube, but the load-carrying

Seismic performance analysis of steel beam to CFST column

Concrete-filled steel tubular (CFST) column to steel beam joint with the ductility and energy dissipation components is a type of connection which is used in prefabricated structures, to improve the capacity of connections and construction efficiency. In this paper, two different type of steel beam to CFST column connections with the penetrated high-strength bolts and end-plate are

The most common are either steel-encased concrete (SRC) where a steel shape is encased within a concrete column or concrete-filled steel tubes (CFT) were an outer tube is filled with concrete. Concrete-filled tubes are generally designated by the shape of steel tube, i.e., rectangular and square (RCFT) or circular (CCFT). SRC RCFT CCFT Figure 1

Behavior of Large-Scale Hybrid FRP-Concrete-Steel

The combined use of a fiber-reinforced polymer (FRP) tube with steel and concrete to form hybrid structural members has attracted increasing research attention. Hybrid FRP-concrete-steel multitube concrete columns (MTCCs) are a new form of such members, comprising an external FRP tube and a number of internal steel tubes, with all the space inside the tubes filled with concrete.

Numerical study of concrete-filled steel composite (CFSC

Concrete-filled steel composite (CFSC) stub columns which were experimentally tested by Tao et al. (2005) were considered in this paper for the verification of the finite element modelling using the finite element software LUSAS. The cross sections of the columns with the lengths ( L) of 750 mm and 390 mm are shown in Figure 1.

This paper presents an experimental investigation of the concrete filled thin-walled welded steel tubes. Square and rectangular columns are tested with and without the bond between the steel profile and concrete. In order to remove the bond in the latter columns a polyethylene (PE) film is placed inside of the steel profiles.

Circular hollow steel tube and square hollow steel tubes were tested and reported in this research (Fig. 2). Refs. [15–24] specifically indicate the results of tests on different types of structural components such as unprotected structural steel-1, circular steel columns filled with bar-reinforced concrete, steel hollow structural section

Nonlinear analysis of circular concrete-filled steel

The confinement effect provided by the steel tube in a circular concrete-filled steel tubular (CFST) short column remarkably increases the strength and ductility of the concrete core. The reliable prediction using nonlinear analysis methods for circular CFST columns relies on the use of accurate models for confined concrete.
