WebConnection Calculator Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws, and wood screws per the 2015 NDS. Both lateral (single and double shear) and withdrawal capacities can be determined. Wood-to-wood, wood-to-concrete, and wood-to-steel connections are possible. WebHankinson's Equation... Hankinson's equation (also called Hankinson's formula or Hankinson's criterion) is a mathematical relationship for predicting the off-axis uniaxial compressive strength of wood ...The formula can also be used to compute the fiber stress or the stress wave velocity at the elastic limit as a function of grain angle in wood ...

WebJun 28, 2007 · Recent tests at the Weyerhaeuser Company Technology Center were aimed at determining the applicability of the Hankinson Formula for predicting the strength of wood loaded in tension at angles to the grain. Small specimens cut at varying grain angles were loaded in tension at a rate of 0.1 inches per minute. WebUsing the Hankinson's formula (with n=2), predict the compressive strength of a clear wood specimen at an angle of 40° relative to the grain (fiber) direction. 12. Predict the compressive strength perpendicular to the grain of a wood specimen with knot of height 0.3 inch. (Note: the height, h, of the specimen when compressed perpendicular to ...
