The column with diagonal ribs is referred to as diagonal ribs stiffened CFST column. This paper summarizes the test results of axially loaded diagonal ribs stiffened and longitudinal ribs stiffened CFST columns comprehensively, followed by further tests of stub columns with longitudinal reinforcing bars...
The ultimate load of axially loaded concrete filled steel tube columns was investigated and design equations are proposed which are based on summing the tangent modulus buckling loads of the concrete core and the steel tube. The tangent modulus loads are calculated using the AISC code method for ...
Axially loaded walls are modelled quite well but the theory is conservative for walls tested eccentrically. Although the inclusion of a strain gradient factor and consideration of nonlinear behaviour would improve analytical predictions for the latter case, these extra factors are not applied to the ...
Ultimate axial resistance will aid the engineer to decide the size and reinforcement of an axially loaded column, whereas the axial and bending moment resistances under balanced failure provide insight into column capacity when it is subjected to bending moment. 展开 ...
摘要: Axially loaded reinforced concrete columns are hardly exist in practice due to the development of some bending moments. These moments could be produced by gravity loads or the lateral loads. First,...关键词: columns double curvature mode eccentric loading equivalent column concept single ...

This paper presents the results of experimental and analytical studies of the performance of axially loaded concrete columns confined with PVC-FRP tubes. Test variables include type of confinement, volume of fiber and FRP hoop spacing. The results indicate that the new hybrid columns exhibited high ...
1. The first is the axially loaded column, shown in Fig. 1 (a). The load is perpendicular to the plate and through the column centroid. It is used in frames in which the column bases are assumed pinned. A layer of grout is used for leveling of the plate and setting it at the ...
As indicated in the preceding section, the ultimate loadPuof an axially loaded cantilevered column such as that Demonstration problems All the columns analysed in this paper are composed of square hollow section (SHS) 203×6.3. This section was selected for three reasons. First, the issues of ...
The current work examines the buckling behaviour of an axially loaded framed spliced steel column. The general behaviour is characterized using a polynomial Rayleigh–Ritz approximation substituted into the potential energy function, in combination with the method of Lagrange multipliers, and the critical...
