| Abstract: | The numerical calculations of blast wave from gas explosion are carried out with the code MSC.DYTRAN.The dynamical responding of a cabin structure of LH-1 offshore platform under inner-blast loads is simulated.The dynamical response characteristics of the cabin structure is studied through the structure damage deformation and energy absorption by components of the cabin structure. |
