Field Study the In-Plain Behavior of the Brick Wall under Subsurface Explosion

Nowadays, design of buildings against shock loads caused by explosion has attracted special attention, due to an increase in terrorist attacks. Thus, introducing the nature of explosion and its loads are regarded as the first step in achieving this goal. Blast is an abrupt release of big amounts of energy in which light, heat, sound, shock wave, and dense air are produced. The present study aims to examine the nonlinear dynamic response of a masonry wall including two openings by the underground explosion that employedto produce earthquake -like waves. In this study, Dynamic analysis is conducted through ANSYS software. Menetrey-Willam and Drucker-Prager are used to model the structure and soil, respectively. Finally, the results of analyzing numerical model based on finite element method were compared with the field data. The outcomes demonstratedthat there is good agreement between numerical results and field data.
