Abstract : The design, analysis, and testing of a buried circular cylindrical shelter has been described in this paper. This shelter may be used for personnel protection in emergency situations like accidental blast, terrorist attack, etc. Various criteria have been used for designing and analysing the shelter. The shelter has been analysed using a software package called ANSYS for finding out the stresses, deflections, buckling load factors, and buckled mode shapes. The shelter was buried under earthcover (1.5 m) and tested for the required loading.
