Simulation CEL explosion of steel-UHPC composite RC beam(column) with multiple encased steel profiles in Abaqus

In this tutorial, the Simulation CEL explosion of steel-UHPC composite RC beam(column) with multiple encased steel profiles in Abaqus  has been done. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. The bar and strip are modeled as three-dimensional wire parts. The steel beam core and TNT part are modeled as solid shape, and the domain as an Eulerian part. You can see a figuer of the assembled parts below

The past decade has witnessed frequent occurrences of localized wars and terrorist attacks. Some important infrastructure such as government buildings, and embassy buildings might be targets for a terrorist bombing attack. Understanding structural response to explosive loads is essential to protect critical infrastructure against explosions. Damage assessment of RC beam has been an active research field for many years due to RC beam being the primary connection and the force transmission in building structures.The damage assessment of RC members is a complicated problem. RC beams will manifest cracks, crushing, and spalling under explosion. These phenomena are affected by various parameters, such as the number of main steel bars, permeability of concrete, stress waveform, detonation point, and air pressure, among others
