The ‘double entry-point’ to design caused by timber remaining ‘working stress’, whilst other materials have long been ‘limit states’, is no longer helpful to professional engineers. To overcome the problem, TRADA Technology, with funding from DETR and TRADA, is undertaking a project entitled ‘Demystifying limit states design in timber’. The project has an Advisory Group, chaired by consulting engineer Stefan Tietz, and includes other practising engineers, timber design specialists, TRADA engineering staff, and an educational representative from the University of Bath. Professionally,
the project involves the Institution of Structural Engineers’ regional branches and the
Professional Activities Group. The UK Glued Laminated Timber Association (GLTA) is also
contributing.
