A detailed nonlinear finite element (FE) modelling approach is proposed to represent the
behavior of precast pre-stressed hollow-core (PPHC) slabs under vertical loading until shear …

Even if precast pre-stressed hollow-core (PPHC) slabs are usually designed as simply
supported elements, continuity with the supporting beam may exist when constructed …

Serious concerns about the life safety risk of hollow-core floors during earthquakes were
raised following the collapse of hollow-core units during the 1994 Northridge earthquake …

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

Hollow-core flooring systems were damaged in Wellington buildings during the 2016
Kaikoura earthquake (7.8 M w) and have been shown to be susceptible to undesirable …

Since the early 2000s, it has been widely recognised that existing hollow-core floors can
pose a threat to life during earthquakes, but only limited and mostly unvalidated guidance on …

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 …

Concrete floor diaphragms of existing buildings are often inadequate to resist tension forces
developed as the diaphragm spans between the lateral load resisting elements. A common …
