Hysteretic behavior of multi-cell T- Shaped concrete-filled steel tubular columns

Seismic Performance of Recycled Aggregate Geopolymer Concrete-Filled Double Skin Tubular Columns with Internal Steel and External FRP Tube

“…This is transcending because the items in the specimen had failed in previous load rounds. The minor fractures of the specimen were gathered at a specific place by advancing the transverse loads, resulting in inconsistent damaged reductions for sides B and A due to non-homogeneity of components and varying local buckling functioning of the STT [ 56 , 57 ]. As a result, the specimen’s strains developed irregularly on these different sides.…”

Parametric Study on the Axial Behaviour of Concrete Filled Steel Tube (CFST) Columns

“…Numerous experimental and analytical studies have been conducted to realize the behaviour of CFST columns with various sectional shapes, such as circular section [12][13][14], rectangular section [16][17], T shaped section [16] and double skin section [18]. Authors concluded that, the behaviour of CFST column is affected by the diameter to thickness ratio (d/t), steel yield strength (f y ), concrete compressive strength (f ck ), axial compression ratio (n) and slenderness ratio, for circular section and also depth to breadth ratio for rectangular section.…”
