A NEW CONCEPT AND ALGORITHM TO TRANSFER BRITTLE AND ARBITRARY LOAD-SLIP CURVES INTO AN EFFECTIVE SHEAR RESISTANCE SUITABLE FOR EUROCODE 4. (LAJ22.A)

This paper proposes a new concept and algorithm to transfer brittle and arbitrary load-slip
curves into an effective shear resistance suitable for Eurocode 4. This algorithm is specifically
for demountable shear connections of composite beams which do not exhibit ductile
behaviour as required in EC4. The algorithm is validated with numerical finite element
models which have been calibrated against experimental results. The algorithm extends the
scope of the code to cover demountable shear connections: it allows the EC4 (EN 1994-1-1)
rules remain applicable for the evaluation of the plastic bending resistance of composite
beams with partial shear connection.
