A beam splice connection joins W12 and W21 steel members using bolted splice and shear plates. The connection features three three-quarter-inch A325N bolts securing a three-eighths-inch by four-and-a-half-inch by nine-inch shear plate at the beam web, alongside flange splice plates matching the flange thickness fastened with groups of four three-quarter-inch A325N bolts. The beam web includes slotted holes with one-quarter-inch radiused corners to accommodate the splice configuration.
