Abstract
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.
