Experimental Study and Numerical Simulation for Explosion and Phenomena of RC Slabs

Abstract

The blast impact dynamic experiment of reinforced concrete rectangular plate with simply supported boundary conditions was performed using explosion pressure simulator. With 3-D FEM software LS-DYNA, the separate solid models of concrete and steel were established and 3-D FEM dynamic analysis of the experiment process was carried out. Compared calculation results to experiment results synthetically, the damage mechanism and failure characteristics of reinforced concrete plate under explosion impact loading condition were got and it is also verified that the H-J-C model can approximately simulate the concrete properties well under explosion impact loading condition.

Effect of corrugated steel angle on the damage characteristics and anti‐explosion performance of corrugated steel–concrete composite structures

“…The damage evolution characteristics and failure mode of concrete slab structures under contact explosion loads are key to analyzing their anti‐explosion performance. Scholars worldwide have extensively studied the anti‐explosion performance of concrete slab structures 3–7 . Research on the anti‐explosion performance of reinforced concrete slabs has been mainly carried out by experimental or numerical simulation methods.…”

“…Scholars worldwide have extensively studied the anti-explosion performance of concrete slab structures. [3][4][5][6][7] Research on the anti-explosion performance of reinforced concrete slabs has been mainly carried out by experimental or numerical simulation methods. On this basis, the damage process and failure characteristics of reinforced concrete slabs have been deeply explored by changing external factors [8][9][10] (such as explosive quantity, detonation distance, and air or water medium) and internal factors 11,12 (such as reinforcement ratio, steel yield strength, and concrete compressive strength).…”
