In addition to the moisture-induced tension perpendicular-to-grain failures discussed above, similar failures can result from a number of different, incorrect connection design details. Improper beam ...

Behold the beam, an amazing structural element that bends when loaded — but one that must not bend too much. A fallen tree spanning the banks of a river was perhaps the first ...

A basic two-dimensional version of the software, suitable for designing basic beams and structural parts, is freely available now online, she says, as the team continues to develop a full 3D version.

Wide-flange is born The mill began rolling the beam in January of 1908 and Bethlehem Steel never looked back. Soon, every developer who wanted to go high did it with the so-called Bethlehem Beam.

No longer confined to vacuum chambers, Plasma Arc Window electron-beam welders could produce high quality welds on large structures such as airplanes and ships.
