Slip and uplift measurements along the steel and concrete interface of various types of composite beams

Our approach is going to consist in showing various experimental results issued from beam tests in laboratory and in comparing them with theoretical results supplied by numerical simulation ; to make shorter the presentation, only the case of simply supported beams will be considered. The data useful to calculation will be deduced whether from push-out and pull-out tests or from direct measures taken on beams. First of all, the numerical model concerned here is briefly presented in its main lines.
