This paper reports the instrumentation and monitoring techniques developed to improve understanding of the early-life behaviour of concrete industrial ground-floor slabs. Concrete strains, temperatures and joint movements were measured using vibrating-wire embedment strain gauges and thermistors, while ambient conditions were monitored to assess their effects. A reliable, accurate and easy-to-implement methodology, developed by instrumenting four types of floor slab (mesh-reinforced long strip, mesh-reinforced jointed large area pour, steel fibre-reinforced jointed large area pour and steel fibre-reinforced jointless large area pour) is described in detail, along with the further developments and modifications to the instrumentation. The methodology developed would be equally applicable to the early-life monitoring of other concrete structural elements. Some sample results of data gathered using the instrumentation methodology developed are included.

“…The findings from the instrumentation of seven sites, discussing the influence of thermal and hygral effects on slab and joint movements, are presented elsewhere 3,4 as are the results of finite element modelling of the slab behaviour. 5 Further information on the research can also be found on the project website. 6…”
