Bolstering-Structural-Integrity-1

DSTA develops resilient military buildings and infrastructure to support the SAF’s defence capability amid tight land constraints in Singapore. In 2012, DSTA’s technology development efforts in the area of building and protective infrastructure were focused on reducing hazards that arise from explosive storage facilities, and building up an understanding of the resilience of multi-storey buildings against progressive collapse.

DSTA worked with overseas defence agencies to perform joint blast tests, thereby sharing expertise and minimising cost. The DSTA team also sharpened its knowledge base by participating in various international expert groups to share analyses and modelling practices.

In August 2012, DSTA conducted a series of small-scale earth-covered magazine tests with international partners and demonstrated the effectiveness of using soil cover to reduce hazard distance. With this build-up of knowledge, DSTA aims to develop guidelines to design ammunition storage facilities with smaller hazard circles, hence relaxing the constraints imposed on nearby military and civilian infrastructure.

In collaboration with the United States Defense Threat Reduction Agency, DSTA also conducted blast testing of a multi-storey structure in December 2012 to study the resilience of local building designs against progressive collapse. This test series, believed to be the first of its kind in the world, will serve to augment the SAF’s capability in structural resilience against weapons effects.
