Simulation air blast explosion over RC column with spiral strip and steel tube cover in Abaqus

In this tutorial, the Simulation air blast explosion over RC column with spiral strip and steel tube cover in Abaqus has been done. The concrete column is modeled as a three-dimensional solid part. The spiral strips and bars are modeled as three-dimensional wire part. The steel tube as cover is modeled as three-dimensional shell part. You can see figures of the assembled parts below

The Johnson–Holmquist-II(JH-2) model is introduced as the constitutive model for concrete material in blasting. However, complicated and/or high-cost experiments need to be carried out to obtain the parameters of the JH-2 constitutive model. In this example, the Johnson-Houmquist model is implanted as input file code for concrete to consider damage variables. The Johnson-Cook hardening and damage is so suitable for the high strain rate deformation, so it used to define the steel material

The dynamic explicit step is selected for this analysis. perform dynamic simulations when speed is important. Explicit dynamics account for quickly changing conditions or discontinuous events, such as free falls, high-speed impacts, and applied loads. The steel reiforcements are embedded inside the concrete column host. The perfect contact is assumed between the concrete column and steel tube. The CONWEP blast method is selected to apply the blast load on the column. The proper mesh and boundaries are applied to the all parts

After the simulation, all results such as damage, failure, stress, strain, displacmeent, and other resutls are available. You can see some figures for the results below
