Effort of the protective structure of the shelter under the influence of an external fire
The paper presents a numerical analysis carried out to determine the influence of the ground surface fire on the strain level of shelter housing with the ground cover. It is assumed that the underground shelter is longitudinal and the fire spans on an extensive area. The area surrounding the housing...

description | The paper presents a numerical analysis carried out to determine the influence of the ground surface fire on the strain level of shelter housing with the ground cover. It is assumed that the underground shelter is longitudinal and the fire spans on an extensive area. The area surrounding the housing was treated as a material with average constant thermodynamic values. The heating and cooling processes were described on the basis of the Fourier’s equation concerning heat conduction in consideration on material, ground and concrete heterogeneous nature. The numeric analysis was carried out in two stages. In the first stage, a quasi-stationary initial temperature distribution was sought in the ground centre and shelter shield. In the second stage of analysis, the fire effect was considered according to the time profile of temperature variation in object. |
