Long-term behaviour of LVL-concrete composite floor beams
The long-term behaviour of timber-concrete composite is characterized by the response of its three components (timber, concrete and connection) to load, moisture content, temperature and relative humidity of the environment.

| Summary: | The long-term behaviour of timber-concrete composite is characterized by the response of its three
components (timber, concrete and connection) to load, moisture content, temperature and relative humidity of the
environment. This paper reports results of a 4-years long-term test on three 8m span laminated veneer lumber (LVL)-
concrete composite floor beams under service load performed in an indoor, uncontrolled, and unheated environment at
the University of Canterbury. The environmental conditions were characterized by either low temperature with high
relative humidity or high temperature with low relative humidity, conditions considered to be reasonably severe and
presumably close to service class 3 according to Eurocode 5. The mid-span deflections were extrapolated to the end of
service life (50 years) and compared to span/200 deflection limit, which was exceeded by all beams.
