| Abstract: | The dynamic response of a cylindrical reticulated shell structure under the impact of the blast waves generated by an in-tunnel explosion is investigated numerically.A three-dimension coupling model consisting of the underground tunnel,soil and a cylindrical reticulated shell structure is established with the ABAQUS software considering the material nonlinearity of the soil,concrete and steel.The accuracy and validity of the coupling model set up with the ABAQUS software is verified by an example.Three grou... |
