| Abstract In recent years, there have been numerous explosion catastrophes due to military and terrorist activities. Such accidents lead to damage structures and human casualties in military and urban areas. To protect structures and people against explosion accidents, more engineering insight on the explosion effect is required to study buried structure performance. However, the blast field test is expensive and risky to conduct. In this study, the nonlinear numerical model is proposed to understand the buried structure performance. The buried structure performance against impact of blast effect is analyzed under three case studies. The response of the buried structure is studied using 2-D finite element analysis (FEA) under the blast effect. The reviewed study cases are used to verify the 2-D nonlinear numerical model. The parametric study is also conducted to choose the suitable numerical model so as to improve the buried structure performance. Different TNT explosive charges are used based on the different case studies. The blast effects on the buried structure are expressed in terms of maximum displacement at different points located at the numerical model and pressure-time history hitting the buried structures. The results obtained by the three case studies have a good agreement with those obtained by the 2-D numerical model of case study. Finally, the proposed 2-D numerical model can be used to give a good estimate to study the performance of the buried structure under the impact of blast loading. | ||
