CURVED BEAM : UNALAM WORDS of the WEEK
WHAT MAKES A CURVED BEAM DIFFERENT ?
A curved beam refers to a beam of constant cross section and typically with a constant radius of curvature. Straight beams are typically fabricated with a slight amount of curvature, or “camber”, but a curved beam will be bent to a much greater degree.
A curved beam may look similar to an arch, but its design is significantly different. A curved beam is designed to span without relying on any horizontal restraint at supports. Beam forces will tend to straighten the
curved beam, so radial tension forces will be present, and southern yellow pine is the recommended species.
