Probabilistic design of mechanically-jointed timber beams using Eurocode 5


A computer program that automates a probability-based design of mechanically-jointed timber Ibeams subjected to gravity loading is presented. The specifications of the EC-5 (1995) and EN 338 timber strength classes were strictly followed in the program development. In addition, first order reliability method (FORM) was adopted in checking the safety of the designed section. Failure of bottom flange due to extreme fibre tensile stress produced the most uneconomical results. The maximum shear stress condition on the other hand, gave the most critical results of design. Therefore it is considered to be the most critical mode failure for mechanically jointed timber I-beams subjected to gravity loads.
