Design, Fabrication and Operation Proposals for Glued-Laminated Timber, Based on Measuring and Modelling Results, Chapter 1: Literature Review and the Results of Examinations of the Spoil of the Glue Laminated Timber Beams
Glue laminated timber beams have been used in an increasing number of cases in the past 50 years. Glue laminated beams are durable constructs if they are manufactured from adequate quality materials and if their installation and operation are performed to a high quality standard. There are however an increasing number of cases of glue laminated beams suffering damage and as a result entire roof structures becoming life-threatening. Because of the arising problems the most important building complexes in Hungary-in which glue laminated beams are used as bearing structures- have been examined, considering both the demage problems of the existing structures and the operating features of the buildings. Later the reasons for the demages were examined with measurements and caculations. From all these observations conclusions and suggestions have been outlined both for the design, construction and operation.
