| Abstract | ||||
| This paper presents the numerical procedure of fluid dynamics for simulating the shock wave loading on RC columns. It starts from the fundamentals of explosion and blast wave as well as prediction of blast loading technique. Modelling procedure of blast wave using AUTODYN including Euler analysis method, and smooth particle hydrodynamic analysis (Lagrange analysis method) are described. The propagation modelling of blast wave is also explained with highlighting on definition of geometry properties, remapping method, boundary conditions, and interaction & contact Points. Validation studies were carried out to compare the results of former experimental researches of blast loading on square and rectangular reinforced concrete columns with results derived from finite element modelling (FEM) using AUTODYN explicit Program. | ||||
