Twist off end bolts
Time related deformation due to sustained loading
Creep
Regarding wood members that are bolted together. This equation is used to evaluate connections that are loaded at an angle relative to the wood grain.
Hankinson Formula
For a wood connection with multiple pieces of wood, each shear plane shall be evaluated as a _______ connection/
Single Shear
The capacity of a wood connection, when anchored with lag bolts is greatest when the wood is loaded _______ to the grain structure.
Parallel
This is based entirely on the support conditions at the top and bottom of the column.
Effective Length Factor
The section modulus for the cross section of a member is related to the
I. moment of inertia of the cross section
II. depth of the cross section
III. bending stress in the member
IV. modulus of elasticity of the member
the section modulus (S) for the cross section of a member is the cross sections moment of inertia divided by the distance from the cross section’s neutral axis to its extreme fibers
Answer: I and II only
The Hankinson Formula
is a mathematical relationship for predicting the off-axis uniaxial compressive strength of wood
