ASSESSING THE DISMANTLED GLUED-LAMINATED STRUCTURE OF A NATATORIUM AFTER 35 YEARS IN SERVICE

The article describes the results of the investigation of the load-bearing capacity of the recently dismantled roof structure of the Csik Ferenc Natatorium in Sopron, Hungary, after 35 years of service. The investigation was aimed at measuring the tensile strength perpendicular to the grain, shear strength and global bending strength of the beams and comparing it to the appropriate design stress values. The results showed that the tensile and shear strength of the beams fulfilled the criteria of the Eurocode 5 standard. The bending strength of the full size beam meets the Eurocode5 design strength requirements for strength class GL 36h. The bending MOE does not fulfil the criterion for this strength class, but is higher than the mean value of a GL 24h beam.
