Assessment of structural bearing capacity in case of internal explosion

The work has developed a method for determining the deformation of bent rod structures during an internal explosion. When consideration quasi-stationary explosion, model load is proposed, taking into account pressure rise section to maximum value at beginning then stationary and decline. in area equal more two peaks. With sufficiently long section, realized here, also determined from energy balance. In case short pressure, develops towards end explosion after drop. solutions are suitable describing beams with different fastening ends limited when does not exceed resistance structure. results can be used assessing capacity elements explosive industries, residential premises, action protective structures.
