چکیده

The steel-concrete composite column comprises a steel core and surrounding concrete. purpose of the system is to provide analysis design techniques for newly invented class laced short columns cyclic axial loads. To minimize increasing density issues associated with nominal strength concrete in consideration depletion natural resources required produce concrete, factory-obtained lightweight sintered fly ash aggregates without basalt fiber are employed. normal-weight containing shown be more ductile than any other column. deformation LNA LSA at failure was found 3.5 mm, whereas LNAF LSAF reached an shortening 4.5 mm failure. have 5.3% energy absorption 11.5% less LNAF. It observed that rigidity these fabricated components had been enhanced. section configuration lacing improved confinement effects ductility. Comparing finite element experimental data revealed strong connection numerical modeling, variance around 8.77%.

Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

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...

Behavior of Hollow-Core FRP-Concrete-Steel Columns Subjected To Cyclic Axial Compression

This report presents the results of an experimental study that was conducted to investigate the effects of key parameters on the compressive behavior of fiber reinforced polymer (FRP)concrete-steel double-skin tubular columns (FSDT). Hybrid FSDT columns have been introduced as a new form of hybrid columns. They consist of an outer tube made of FRP and inner tube made of steel, with sandwiched c...

Experimental investigations on the softening and ratcheting behaviors of steel cylindrical shell under cyclic axial loading

In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...
