Lap splice in a lattice girder system

Övrigt konferensbidrag, 2005

A detailing of load-carrying joints between lattice girder slabs without any reinforcement across the cast joint was studied. The behaviour and capacity of the cast joint between the precast concrete and the in situ cast concrete is very important for this detailing. Two types of detail tests of the cast joint were carried out: one type where the cast joint was loaded in shear and one in tension. Furthermore, the detailing of the joint between two precast concrete panels was tested in bending in full-scale tests. The detail tests were used to calibrate a model of the cast joint, which was then used in finite element analyses of the full-scale tests.
