Abstract
A built-up beam includes a pair of I-beams each having opposing flanges, a web that extends between the opposing flanges, a plurality of flange openings in each of the opposing flanges, a plurality of web openings in the web, and a plurality of bolt holes in one of the opposing flanges. The I-beams are stacked together flange-to-flange in a stacked beam configuration and a plurality of bolts extend through the plurality of bolt holes and secure the pair of I-beams together in the stacked beam configuration.
Claims11
A method of fabricating a built-up beam, comprising:
- obtaining a pair of I-beams, each I-beam having a uniform cross-sectional profile over an entirety of a longitudinal length thereof;
- for each of the pair of I-beams, cutting a plurality of web openings and a plurality flange openings in the I-beam to vary the cross-sectional profile of the I-beam over the longitudinal length thereof;
- for each of the pair of I-beams, cutting a plurality of bolt holes distinct from the plurality of flange openings in one of opposing flanges of the I-beam along the longitudinal length thereof;
- stacking the pair of I-beams together flange-to-flange to form a stacked beam configuration in which the plurality of bolt holes of each I-beam align with each other;
- and
- bolting the pair of I-beams together via the plurality of bolt holes to secure the pair of I-beams together in the stacked beam configuration.
