Publications:

It is, of course, not possible to give a complete list of all publications of a lifetime, working more than 80 hours a week and moreover endless lists of titles will not give any information. Publications on civil engineering problems and on concrete can be found in the reports and the references in these reports of the Consultant bureau Ir. J.G. Hageman. A thesis was written on concrete mechanics but not published and probably can be delivered by the Concrete department of the TU-Delft or by Prof. Bruggeling. Publications on timber engineering can be found in the catalogue of the Section of Timber Engineering of the TU-Delft and the Research Activities Reports of the TU.

For this overview here it is only important to mention the last publications only of new theoretical derivations that are related to the now actual projects of the Delft Wood Science Foundation.

Recent publications will be available on this website and can be downloaded and will be mentioned and discussed there.
An overview of publications about new theory of the old Wood Science Foundation of before 1993, done in cooperation with the TU-Delft, over a period of the last 5 years, related to the now actual projects is given in the following list because it can not be found elsewhere. Reports and EC-reports are not mentioned and can be found in the catalogue of the Section of Timber Engineering of the TU-Delft.
