Based on observed behaviour in previous earthquakes and subsequent extensive research,
it is now well understood that hollow-core floors can be highly vulnerable to earthquake …

Despite development of detailed assessment procedures based on extensive past research,
little guidance has previously been available regarding how to retrofit deficient precast …

Precast concrete floors comprise precast floor units with in-situ (often lightly) reinforced
concrete topping to form a composite floor system that generally also functions as a …

Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand
in 2010-2011 and 2016 respectively, highlighted that floor systems can be heavily damaged …

Existing precast hollow-core floors commonly have insufficient seating lengths, which makes
them prone to Loss of Support failure when subjected to earthquake-imposed demands. A …

A simple and cost-effective method of improving the seismic performance of RC structures is
explored in this paper. Twelve archetypal RC moment frames were developed following the …

Precast prestressed hollow-core floor units are a common precast floor system. Hollow-core
floor units were observed to sustain critical damage during earthquakes, where deformation …

Hollow-core floors have been recognised to have a potentially poor seismic performance
since the 1994 Northridge earthquake, with subsequent research leading to significant …

Precast concrete floors are a prevalent feature of New Zealand's existing building stock.
While it is well understood that older precast floors constructed using hollowcore or double …
