“…Improving the transverse reinforcement ratio can effectively increase the shear resistance of the beam and avoid diagonal shear failure, although the maximum shear resistance was limited by the diagonal compression failure of concrete. While an increase in the concrete strength can improve the shear capacity of the beam (Liew and Wang, (2011) Lin et al (2020)), it also results in brittle failure occurring more easily (Sebaibi et al, 2012). Similarly, for SCS panels, Sohel et al (2011) found that the ultra-high strength concrete core does not improve the overall blast-resistant performance of the panel due to the brittleness of the concrete.…”

To increase the blast resistance of reinforced concrete or steel–concrete composite structures with long span, an innovative prestressed steel-grouting material composite beam with a hollow web is proposed. In the beam, the flange is filled with grouting material, and an I-type steel web is used to strengthen the shear capacity, and a prestressed tendon is placed in lower flange to improve the flexure resistance. The following three specimens were designed: a double hollow tube, a double tube filled with grouting material, and a prestressed double tube filled with grouting material. The specimens were tested against close-in blast, and overpressure, deformation, and strain were recorded. In order to further understand the blast-resistant performance of the beam, a finite element model was developed by commercial software LS-DYNA. A good agreement between the numerical predictions and test data was observed. It is indicated that the proposed prestressed steel-grouting material composite beam with hollow web exhibits excellent blast-resistant performance.

“…The sandwich structures with ultra-high performance concrete (UHPC) can be adopted for high performance composite structures, such as nuclear shielding walls. Lin et al (2020) studied the failure mechanism and failure patterns of SCS sandwich beams with steel fiber-reinforced UHPC. Compared to sandwich beams with ordinary concrete, sandwich beams with UHPC tend to fail by flexural failure rather than shear failure.…”

The present study conducts experimental, numerical and analytical investigations on the responses of double-layer Steel-RULCC-Steel sandwich panels subjected to concentrated impact loading. Seven full-scale SCS panels are designed and fabricated with different number of concrete layers, degree of composite action, type of shear connectors, and proportion of added rubber powder. The influences of these design parameters on the failure mode and response behavior are quantified and discussed. Advanced FE simulation is performed in LS-DYNA to extract more information on the strains, stresses, and energy absorption of the panel during the impact. Finally, a single-degree-of-freedom (SDOF) model and a two-degree-of-freedom (TDOF) model are developed to predict displacement-time and load-time responses of the double-layer SCS panels based on the quasi-static load-displacement relationship proposed also in this paper. The comparisons with test results demonstrate that the SDOF model overpredicts the peak deformation of the panel if the hammer weight is much larger than the effective panel weight. In contrast, both the FE model and TDOF model provide a much more accurate prediction on the impact responses of double-layer SCS panels, including the peak impact force, peak deformation, and residual deformation.
