“…The initial value of velocity (V 0 ) for all models was taken 1000 mm/sec while, the residual velocity (V R ) after perforation was captured. Then the ballistic limit of the studied models was calculated from the following relation:-Absorbed energy for computing ballistic limit = ½ m (V 0 ) 2 …”

“…Double-skinned CFST columns have some advantages over single-skinned CFST columns. From a structural point of view, double-skinned CFST columns have higher uni-axial strength (Han et al, 2011;Tao et al, 2004;Uenaka et al, 2010;Wright et al, 1991;Yang et al, 2008;, bending stiffness, moment capacity Lin and Tsai, 2001;Lu et al, 2009;Tao and Han, 2006), better ductility and excellent seismic performance (Zhao et al, 2010). The strength-to-weight ratio is largely improved owing to the cavity inside the inner steel tube.…”

It has been demonstrated that high-strength concrete (HSC) is able to improve the strength-to-weight ratio of reinforced concrete columns and maximise the usable areas of tall buildings. However, closely spaced transverse reinforcement needs to be installed to provide stronger confinement for averting brittle failure of HSC. To resolve the problem, double-skinned concrete-filled-steel-tubular (CFST) columns have been advocated, which eliminates the steel congestion problem for better concrete placing and reduces the concrete arching action thus providing a more uniform confining pressure. Despite these advantages, a major shortcoming of double-skinned CFST columns is that imperfect interface bonding occurs in the elastic stage that reduces elastic strength and stiffness. Thus, the authors proposed to adopt external confinement to restrict the lateral dilation of the outer tube of double-skinned CFST columns. To verify the effectiveness of the proposed external rings, a total of 20 double-skinned normal-and high-strength CFST columns were tested. From the test results, it was observed that the stiffness, axial load-carrying capacity and ductility of ringconfined double-skinned CFST columns were significantly higher than the unconfined columns.

“…Among these, conventional headed stud connector and throughthrough connectors are commonly used in steel-concretesteel sandwich construction. Resistance of face plates against tensile separation depends on pull out strength of headed studs in conventional headed stud connectors [4,5]. Steel plates and through-through shear connectors are fabricated in factory and concreting is done at site, thus facilitating ease of construction [6,7].…”

Steel-concrete-steel (SCS) sandwich construction combines the advantages of both steel and concrete and finds application in numerous areas such as bridges, protection against impact and blast loads, flooring system etc. Shear connector is a critical component of SCS system. In the present study, two new configurations of bidirectionally inclined shear connector are proposed. Response behaviour of SCS beams with bi-directionally inclined connector is obtained through numerical investigations. Finite element models of SCS beams are generated by using a simplified approach that employs solid, plate and beam elements to represent concrete, cover plates and shear connector respectively. Behaviour of concrete is represented using concrete damaged plasticity model, while steel behaviour is modelled by using bilinear stress-strain curve. Beam is simply supported and is subjected to a central concentrated load. Nonlinear static analysis is carried out to obtain load-deflection response. Numerical model is validated by solving a SCS beam with through-through connectors, which was experimentally investigated in literature. Responses from bi-directionally inclined connectors are compared with that of through-through connectors. Bi-directionally inclined connector is found to be more ductile compared to that of through-through connector, while the load carrying capacity remains same. Parametric study is carried out by varying the cover plate thickness, angle of inclination and diameter of the connector to study their influence on the behaviour of the steelconcrete composite beam.
