The St. Jan car park consists of three subterranean levels with a total of 1040 parking spaces. In September 2014, during construction, several beams on the upper levels were revealed to have insufficient load capacity. The solution was to apply strips of CFRP laminates, glued to the soffit of these beams. The composite action of the concrete, its rebar and the additional CFRP laminates then allows for higher loads. Structural calculations were carried out on the basis of CUR Aanbeveling 91, which requires testing to verify the strength of the glued connection in order to achieve sufficient composite action.
