报告摘要：
Timber is the one material that was common to almost every historic construction, whether as floors and roofs in predominantly masonry buildings, or as the main building material.
It is also the common building material most vulnerable to the agents of destruction, including insects, fungi and fire.
Structural timbers that appear to be by visual inspection to be in good condition can be severely degraded beneath the surface. Conversely, timbers that appear to be severely degraded by visual assessment often retain sufficient strength to be kept and conserved. Too frequently, timbers that should be repaired or replaced are missed, but even more often, timbers that should be retained and conserved as part of a historic structure are lost.
This presentation will discuss and illustrate some of the non-destructive techniques that can be used to locate, identify and assess structural timbers in historic buildings.
