Assessing the vulnerability of Shiekh Bahaei’s bath under the blast wave

The purpose of this study is to investigate the vulnerability of Shiekh Bahaei’s bath under the blast wave. This study was performed as a numerical study using software analysis. The method of three-dimensional nonlinear finite element analysis was selected by Abaqus software. Nonlinear dynamic analysis method was selected to determine the moment-to-moment response of the structure to the explosive load. The Drucker Prager criterion is also used to model building materials in Abaqus software. The accuracy of finite element modeling results was ensured by comparing the modeling results with the laboratory sample. The finite element model of Shiekh Bahaei’s bath was modeled in Abaqus software and nonlinear dynamic analyses under the blast wave were performed. Then, the results were compared in the form of tensile damage meters and displacement-time diagrams. Based on the results of this study, the location of the breakdown and the amount of displacements in different parts of the bath under the blast wave were determined.
