Gholipour et al. [8] | FEA (LS-DYNA) | Reinforcement configurations | Increasing the rate of impact from 2 m/s to 12 m/s, makes specimen failure mode in shear and flexure |
(i) Low shear (L22S6) |
(ii) Low flexure (L12S12) |
(iii) Sufficient shear-flexure (L22S10) |
Loading sequences | Impact-blast and blast-impact load scenario revealed local spallation and direct shears, respectively |
(i) Impact-blast load |
(ii) Blast-impact load |
Time lags | Large flexural bending moments were obtained when the sequential explosion detonated at the time of peak bending moment |
(i) Low-rate impact (2 m/s) |
(ii) Middle-rate impact (6.86 m/s) |
(iii) High-rate impact (12 m/s) |
|
Gholipour et al. [9] | FEA (LS-DYNA) | Loading sequences | Severe damage (spallation) was obtained beneath the depth of the beam |
(i) Impact-blast load |
(ii) Blast-impact load |
Time lags | Increasing the time lag from 2.1 ms to 20 ms revealed global shear failure mode |
(i) tL = 2.1 ms |
(ii) tL = 5.0 ms |
(iii) tL = 10 ms |
(iv) tL = 20 ms |
Beam depths | Both peak and residual displacements increase when decreasing the beam depth |
(i) D1 = 0.15 m |
(ii) D2 = 0.20 m |
(iii) 3 = 0.25 m |
|
Gholipour et al. [9] | FEA (LS-DYNA) | Span lengths | While changing the span length from 0.9 m to 1.9 m, large flexural bending moment was obtained |
(i) L1 = 0.9 m |
(ii) L2 = 1.4 m |
(iii) L3 = 1.9 m |
Longitudinal reinforcements | Increasing flexural steel ratio drops the damage index values and the path of damage |
(i) Low flexure (C13T16) |
(ii) High flexure (C20T25) |
Transverse reinforcements | Beam with sufficient shear detail had small spalls |
(i) Low shear (Фt = 6 mm @ 15 cm) |
(ii) Sufficient shear (Фt = 16 mm @ 5 cm) |
