Our client was improving the living accommodation for staff at its compound in a politically unstable area of the world. As a result, temporary housing needed to be upgraded to meet required safety standards. They asked our Advanced Technology & Research Centre to design a roof for an existing building that would provide protection in case of mortar attack.
Mortar roof designed and tested by our expert team
Our team analysed the potential impact of a mortar blast and designed and tested the solution. It involved a two-layer construction which is lightweight and ductile. This meets the requirements for seismic impact while offering the required protection against mortar explosion. The top layer consists of plywood offset from the load-bearing steel structure. The second roof layer is weighted with sandbags to absorb shrapnel from the blast and delay the building response to the shock wave.
We also assessed the safety of an older existing mortar roof, which had been designed for protection from smaller weapons which had been common at the time. Using non-linear methods to model the impact of larger mortar blasts, we explored the displacement and impact at various points of the building. This enabled us to recommend strengthening measures to provide additional protection.
