| description | A three-dimensional refined numerical simulation model of corrugated steel-concrete slab composite structure under contact explosion load was established by using FEM-SPH coupling method to explore the anti-explosion performance of corrugated steel reinforced concrete slabs with different thicknesses. The influence of corrugated steel thickness on the dynamic damage evolution characteristics, anti-explosion performance and shock wave propagation mechanism of composite structure was investigated. The results show that the maximum error between the simulation results and the experimental results of the crater diameter of the concrete slab and the mid-span displacement of the corrugated steel in the corrugated steel-concrete slab composite structure is 1.6 % and 2.3 %, respectively, which verifies the effectiveness of the simulation method. The mid-span displacement, peak stress and acceleration at the center point of corrugated steel in corrugated steel-concrete composite structure decrease with the increase of corrugated steel thickness, while the energy absorption value increases with the increase of corrugated steel thickness. The mid-span displacement of 12 mm thick corrugated steel is 83.4 % lower than that of 3 mm thick corrugated steel. The failure mode of the composite structure under the same explosive equivalent is mainly manifested as the crater and penetration failure of the concrete slab, and the damage range gradually decreases with the increase of the thickness of the corrugated steel. The failure volume of concrete slab in the composite structure decreases with the increase of corrugated steel thickness, while the energy absorption value of the composite structure increases with the increase of corrugated steel thickness. The research results can provide a theoretical basis for the application of corrugated steel-concrete slab composite structure in the field of structural anti-explosion protection. |
