The structural channel is not used as much in construction as symmetrical beams, in part because its bending axis is not centered on the width of the flanges. If a load is applied equally across its top, the beam will tend to twist away from the web. This may not be a weak point or problem for a particular design, but is a factor to be ...

In a dashcam video captured in Harrisburg, Pennsylvania on Tuesday, one driver experienced a thankfully not deadly, but still frightening ordeal when a load of construction materials fell from a ...
True cruck or full cruck: The blades, straight or curved, extend from a foundation near the ground to the ridge. A full cruck does not need a tie beam and may be called a "full cruck - open" or with a tie beam a "full cruck - closed". [7] Base cruck: The tops of the blades are truncated by the first transverse member such as by a tie beam. [7]
