The Grasett Park is a glass art sculpture commissioned by the Government of Ireland, to be built in the City of Toronto, to honor the sacrifices made by Dr. George Grasett and his Canadian colleagues to accommodate Irish famine refugees that arrived in Toronto in 1847. The sculpture introduces a series of glass panels positioned like a “house‐of‐cards”, with structural glass panels up to 7 m tall. They generally consist of pair(s) base panels that supports the upper panel(s), all stabilized by rod bracings connected with stainless steel point fixings. Due to the complex geometry and high level of concentrated load, the point fixings are custom designed to allow grout filling within oversized glass holes to minimize additional stress concentration introduced by uneven bearing. Since the localized effects and global effects of stress are not independent, the detailed point fixings are meticulously modelled within a global finite element model. The glass panel is designed based on CGSB 12.20‐M89 and adapts design principles for point fixings introduced in DIN 18008. Typical upper panels are found to be adequate at 3 layers of 10 mm thick fully‐tempered glass, while lower panels are 5 layers of 12 mm. The maximum stress is limited to approximately between 60–80 N/mm2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
