The increase in global terrorism in the past several decades has resulted in the retrofit of window glass tox000D
increase its blast resistance. Most windows in high profile buildings are often retrofitted with anti-shatter filmx000D
to mitigate injuries and fatalities due to glass shards. When the anti-shatter film is, however, anchored tox000D
window frames, blast loading is transferred to the window frames and ultimately to the structure of the façade.x000D
Conventional windows often lack adequate strength to resist the imposed blast loading, resulting inx000D
dislodgement of retrofitted windows accompanied by their projection into the interior of buildings with a highx000D
capacity to cause injury and fatality. Post-installed anchors are recommended for upgrading anchorage ofx000D
window frames to the structure of the façade. However, limited information is available for design of anchorsx000D
subjected high strain rates such as blast and impact loading.x000D
The proposed project will test post-installed mechanical anchors subjected to high strain rate loading generatedx000D
in a drop-mass test frame as a first step to understanding behaviour of post-installed mechanical anchors underx000D
blast loading. The results from the tests will provide much needed information for the design of blast resistantx000D
window systems. Information that will also assist Federal Government departments such as Global Affairsx000D
Canada and Public Works and Government Services of Canada to design blast resistant structures in Canadax000D
and abroad. This is particularly important for the safety and security of Canadian Embassies abroad and highx000D
profile government buildings in Canada requiring blast protective design.
