The paper describes experimental research in the real behaviour of connections and its application to the design and realization of new types of timber structures. According to the connection type, primarily dowelled joints with slotted-in steel plates made from solid and glulam timber have been examined. A vital factor in designing joints of timber structures is respecting wood properties related to its changes in humidity. It is namely the case of strength changes as well as volume changes in particular directions. The experimental tests have been used to evaluate the influence of material strength, diameter and dowel number on the load-bearing capacity of joints. Substantial strengthening of joint's load-bearing capacity can be attained by eliminating transverse tensile stresses in the region of dowels. Thus the conclusions derived from the experimental research and from the real behaviour have been implemented by the authors to develop new types of timber structures.
