Abstract—Steel is the main material in the industrial sector. The material must have high strength to withstand explosive forces or loads that can occur at any time. Accidents are inevitable if no countermeasures or forecasts can be used as a reliable reference for designing mitigation or evacuation plans. To avoid such accidents, this research aims to develop a pipe structure that has high structural resistance to explosive loading that may occur due to internal explosions in the pipe. The research method used is the simulation method to determine how the structure responds to the blast load and how much deflection occurs in the structure at each load variation. This research was designed and tested using finite element analysis in ABAQUS/Explicit. Validation of the simulation was carried out with a comparative study of the pioneer experimental results. Analyses were conducted with numerical parameters (TNT loading and mesh size variation) and physical parameters (material variation). The analysis results showed that numerical parameters (mesh variation) affected the accuracy of simulation data, while physical parameters affected the performance of steel pipe shaped structures.
