Wood is one of the most intriguing structural materials and the only one
that is truly renewable. Along with stone, wood is the oldest structural
material on the planet and has been extensively used throughout human
history. Due to its aesthetical value and positive environmental impact,
wood has experienced a renaissance in construction.
As a biodegradable, hygroscopic, non-isotropic material, wood presents
special challenges for a professional and requires through knowledge
ranging from biology to continuum mechanics.
This state-of-the-art report reflects the current knowledge in the area
of in situ assessment of the physical and mechanical properties of wood
structures. Nondestructive, semi-destructive and destructive methods are
described in a systematic manner where technology, equipment and
limitations are discussed. Some of the discussed methods are used in
other materials such as masonry and concrete. Most of the methods,
however, are specific to wood and special qualifications are required to
understand and apply these methods effectively. Existing methods are
constantly improved and new methods are being developed. This report
includes methods that are used in practice or have shown significant
promise and have a body of knowledge that supports statements made in
this report.
This is a useable tool for professionals, researchers, educators and
students
