Measurement of the shear modulus of wood by static bending tests

Journal of Wood Science, 1998
When measuring the shear modulus of wood by static bending tests, the basic theory is dependent on Timoshenko's bending theory. The shear modulus obtained by static bending is a much smaller value than that derived by other methods. We examined the applicability of Timoshenko's theory and propose an empirical equation that can derive the shear modulus ...

Influence of loading point on the static bending test of wood

Journal of Wood Science, 1998
We conducted three-point bending tests by changing the condition at the loading point and then examined the influence of the loading point on the test data. Yellow poplar (Liriodendron tulipfera L.) was used for the tests. First, using loading noses with various radii, static bending tests were conducted by varying the depth/span ratios.

Structural response of concrete-filled elliptical steel hollow sections under eccentric compression [PDF]

, 2012
The purpose of this research is to examine the behaviour of elliptical concrete-filled steel tubular stub columns under a combination of axial force and bending moment. Most of the research carried out to date involving concrete-filled steel sections has

Accurate identification of cross-sectional bending stiffness in large-scale wind turbine blades through static loading test

, 2023
To ensure the safe and stable operation of wind turbines, it is essential that the blades have sufficient bending stiffness to prevent excessive deflection and tower impact.
