Open and flexible architecture allows flexible use of buildings. A way to improve timber buildings in this direction is by introducing moment–resisting frames with rotationally stiff beam–to–column connections. In the present paper, a new concept for a beam–column moment–resisting timber connection is presented. The connection consists of threaded rods inserted with inclination to the beam and the column joined by use of purpose-made steel rings as coupling parts. Moreover, the stiffness requirements with respect to serviceability limit state are evaluated by use of finite element analysis, for a set of moment-resisting planar timber frames with different parameters. Comparing the experimental results for the prototype connection to the stiffness requirements obtained by FE analyses it was concluded that moment-resisting frames up to 8-10 stories can be used to provide the necessary lateral stiffness in timber buildings.
