This paper studies the buckling behaviour and design of welded I-section stainless steel columns. Experimental numerical structural performance data together with methods for columns available in literature have been collated reviewed. A modelling programme including validation parametric has carried out to supplement experimental assessment existing codified proposed flexural formulations Colu...

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...

With the growing demand for bearing capacity of columns, large-section angle steel (LAS) columns have been widely adopted. Q345 is most commonly used steel, but research on axial compression stability LAS mainly focuses steels with 420 MPa and above. In order to study buckling behavior a total 96 specimens are subjected tests. The test results compared specification analyzed. Based data, an acc...

In this paper, a new type of steel-concrete composite member, concrete-filled core steel tube with outer angle steel plank reinforced concrete stub column, is proposed and a series of nonlinear 3D(three-dimensional) full-range numerical calculations under axial compression are carried out, some important factors are analyzed, such as the strength of the concrete, the steel tube and the angle st...
