AB  - Ground floors of industrial buildings, fully supported on the ground or piles, are usually made
of several concrete segments connected through free-movement construction joints. These joints
should provide shear load transfer of the slab and minimise its vertical displacements while
allowing slab horizontal movement to prevent damage due to concrete dry shrinkage. The
construction joint “Dilat 08”, consisting of round steel dowels and steel formwork, was
experimentally tested in a laboratory environment to determine its behaviour to shear load. The
experimental double-shear setup consisted of three slabs connecting through the “Dilat 08” join
system, with two side slabs fully supported on the base and the middle slab on which the vertical
loading was applied. Specimens were formed with a gap of 10 mm between adjacent slabs to
simulate the construction joint opening. Two construction joint orientations were investigated
introducing the vertical load to the slab with a steel plate on the edge and to the slab with an
angle profile on the edge. Experimental testing of both specimens resulted in construction joint
failure due to concrete cracking around steel dowels, near the edges of the middle slab. The
investigation confirmed that the joint orientation affects the joint shear response, demonstrating
larger joint resistance when the steel plate is installed in the slab subjected to failure. Although
contributing to the joint bending stiffness before formwork installation on the site, the horizontal
leg of the angle profile decreases the joint resistance. Experimentally obtained joint resistance
was compared to the design values of resistance according to Technical Report 34 and EN 1992-
4, highlighting a considerable difference between the two analytical approaches. The comparison
between the “Dilat 08” and three types of free-movement joints available on the construction
market showed that “Dilat 08” features larger resistance according to Technical Report 34, but
it also weighs more.
