Investigations on the impact of explosions on buildings have been carried out widely in the world, spreading nearly a century in developed countries such as the US, the UK, Australia, and Russia. Achievements in the area have contributed to enhance the buildings' safety; more importantly, they have helped protect citizens in wars and terrorist attacks. In Vietnam, such investigations on the behaviors of buildings under those special loads are still limited, mainly due to the lack of funding. These studies have been carrier out mostly under the supervision of the Department of Defense, whereby results are kept confidential. However, the society has experienced changes, including more frequent explosions such as from terrorist attacks and gas accidents. This requires more research attention on the impact of explosions on commercial and residential buildings. Studyprovided with a comprehensive review of the loads from terrorist attacks on buildings; study by Pham Thanh Tung focused on the behavior of a concrete wall to the explosion load in a linear environment (lD). This study extends study research scope by considering a 2D working plane with various restraint conditions to compare the results with those of the first case. To produce a more precise assessment, it is necessary that experimental studies are carried out to consider other factors such as materials' strength, steel ratio, steel structure in the two working planes, and the dimemsions of the concrete components. The author would like to thank Assoc. Prof. Dr. Ngo Due Tuan (University of Melbourne, Australia) and Assoc. Prof. Pham Thanh Tung (National University of Civil Engineering, Vietnam) for their support and assistance with useful documents and references and for their appreciation of the benefits to be gained from this research.
