- Abstract
Nails in wood construction – fundamental research and continuous standardisation The nail as a load‐bearing timber fastener is well known today. But 100 years ago, it was different: its structural use was not allowed. This changed with the beginning of systematical research at the end of the 1920s. Since 1933, the nail has been part of the German regulations and has been widely used ever since. For much of the 20th century, it served as the highly efficient fastener of choice especially in roof structures such as board and plank trusses. These material‐saving load‐bearing structural elements were always in demand due to the periodically recurring scarcity of material resources and are an important part in construction history. The following article deals with the research of the load‐bearing behaviour of nails and the standardisation that has constantly accompanied it. The achievements of individual research projects are presented. A timeline shows the connections between research and standardisation. Tables and graphics illustrate the changes within the standards from the first DIN 1052 in 1933 to the first independent timber construction standard in the DDR, TGL 112‐0730, from 1963 to DIN 1052‐1988. Reference is always made to the Eurocode 5 valid today. In general, it can be seen that a large part of today's knowledge still goes back to the basic research of the 1930s.
