The damage degree of RC two-way bending slab can be obtained by the following steps.
The original load-carrying capacity of RC two-way bending slab is obtained by some numerical simulations.
The damage degrees of RC two-way bending slab under different explosive weights is shown in Figure 13.
From Section 3.3, the failure mode of RC two-way bending slab changes from flexural failure to direct-shear failure as the explosive position is from center to the boundary.
