In this paper an experimental program on concrete-filled steel tubular columns subjected to eccentric loads is presented. The have different cross-sectional configurations, including single (CFST) and dual (CFDST). response of all the was studied physical state specimens after tests checked. level utilisation achieved by each type column in relation its resistance analysed together with influen...

In this study, the mechanical properties of different CFST column shapes, including circular, rectangular, square, square with rounded corners, and triangular, are all analyzed compared using ANSYS R2 2021 software. Total deformation, equivalent stress in concrete steel, elastic strain characteristics various shapes also compared. axial load as well highest that columns can support. Comparing c...

A convenient family member of composite columns is concrete filled double skin tube (CFDST); it contains two tubes concentric steel and also shell that there between them. The superior or equal potential offering characteristics CFDST are more than counterparts classical (CFST). purposes the present study to provide experimental investigation results into prestressed load-carrying capacity colu...

Recycling or utilization of industrial waste is becoming more popular as people become environmentally conscious. Silica fume a by-product the smelting process in silicon and ferrosilicon industries. This study examines mechanical behavior steel tubular composite column filled with conventional concrete silica experimentally under axial compressive loading. For study, variability tube thickness...

This study mainly presented a pseudo-static experiment on two full-scale square CFST short columns with the cross-sectional width of 600 mm under combined constant axial load and cyclic lateral load. The seismic performance were investigated. Meanwhile, plastic hinge length specimens was discussed. test results that suffered bend-shear failure. local buckling steel tube occurred at end core con...

Among many tasks to be done by the state, most significant is a social-economic one i.e. provision of its citizens with affordable, long-lasting, energy- efficient and economical housing. One ways doing given task application concrete-filled steel tubular (CFST) structures, for elements building, circular, square or rectangular type. It also possible use such structures not only new housing sto...

Structural bolts have been widely used in prefabricated construction to connect one steel column another due their and structural benefits. In recent years, innovative column-to-column (PCC) connections using normal developed simplify the process of concrete-filled tubular (CFST) columns transfer upper load bottom through bolt-coupler connection. The PCC connection are under compression. Theref...
