- Abstract
Nails in wood construction – fundamental research and continuous standardisation For a long time, the load‐carrying capacity of nails and nailed connections in timber structures was regulated only by tables based on experimental investigations. In the last 100 years, different researchers investigated the load‐deformation behaviour of these connections and developed models with which the load‐carrying capacity and deformation behaviour of nails can be estimated very precisely on the basis of analytical equations. At first used in material saving construction in economical difficult times, nails are nowadays mainly used for the connections of the sheathing to the ribs for light‐frame elements. In the following article, the research and development of the load‐carrying capacity and deformation behaviour of timber‐timber connections with nails as fasteners is explained chronologically and in detail. Different methods to determine the load‐carrying capacity are presented. Mechanical phenomena that have been discovered stepwise are dealt with. Actually, very individual connections can be verified by using code regulations. In addition, it is possible to determine the stiffness of the connection. Tables and graphics illustrate the milestones of the historical development and specifically compare the normative regulations since the introduction of the nail in engineered timber construction in Germany. Here it can be shown that despite the constantly changing definitions, the calculation results regarding the load‐bearing capacity has remained in a similar order of magnitude since 1933 until today.
