The paper explores the possibility of using flexible adhesives to dissipate energy in CLT buildings
during earthquakes. In the first series of tests, a rod glued in a CLT panel with flexible adhesive was investigated. The
connection was tested in pull-pull configuration using cyclic,...

wood modification
Finding efficient ways to decrease wood decay caused by fungi is an important issue in the timber
construction. A possible way to avoid wood decay by fungi is by reducing the water content of
wood, since water is a primary condition for fungal growth. Bulking of the wood cell wall by
chemical...

Presents and overview of wood modification activities and uses in Slovenia.
As of early 2018, Slovenia has two main providers of thermally modified wood. One company developed its own process while the other firm provides treatment. In addition to Slovenia’s wood modification...

The objective of this study was to develop and assess the efficacy of two experimental methodologies for the maleinisation of lampante oil to be used for wood protection.
Two maleinisation techniques were used to chemically modify low-value lampante oil in an attempt to limit leaching, increase...

The market for new durable products of modified wood has increased substan- tially during the last few years, especially in Europe. This increased interest depends partly on the restricted use of toxic preservatives due to increased environmental concern, as well as the need for reduced...
This paper uses network analysis of two fields to demonstrate the value of the technique, and to examine how the fields have changed over time and to what extent they overlap. This was of interest for a COST Action (FP1407, ModWoodLife: http://costfp1407.iam.upr.si)
