Description
Summary:This paper describes newly developed semi-destmctive testing methods that can be used to examine the in-situ mechanical properties of timber structural members. The methods can be used to measure tensile modulus of elasticity and strength, density and moisture content. Special devices to extract micro-tensile and compression specimens were developed and tested in a laboratory environment. The technique gives direct measurements of tensile strength and modulus of elasticity of the material without compromising the integrity and strength of the structure under investigation. 1 Introduction Wood is the oldest structural material, and a significant number of tim
