Understanding clearance dimensions is crucial for the efficient assembly of structural connections between beams and columns or between beams themselves. This guide outlines essential dimensions, including center-to-center distances (Dimension A), back of connection angles (Dimension B), and setback clearances (Dimension C). It also discusses the required calculations for connection beams, such as the actual length needed for fabrication (Dimension D) and nominal setback clearance (Dimension E). Cope cuts and their importance in ensuring smooth beam intersections are also covered.

  1. Structural Drafting Assembly Clearance Dimensions

  2. Clearance Dimensions for Beams Connecting to Beams In order for members to assemble readily, clearances are required between beams and columns or beams and beams. The dimension values can be found in the Dimensions and Properties Tables of the AISC manual.

  3. Clearance Dimensions for Beams Connecting to Beams Dimension A: Is the given center to center distance from the main beams. This dimension is found on the framing plans. Dimension B: Dimension from the backs of the connection angles (A - (C1 + C2)) Dimension C: Clearance dimensions for the connection angles. This dimension is also referred to as "Setback." Note that the C dimension is calculated using the beam that is being connected to. C = (tw / 2) + 1/16 Dimension D: Actual length of connection beam. This is the dimension that the fabricators need to cut the beam to proper length to fit in the assembly. (D = B - (E1 + E2) Dimension E: Nominal Setback clearance for beam. This is generally 1/2".

  4. Clearance Dimensions for Beams Connecting to Beams For Example: Given a W12 x 35 is connected to two W18 x 60 beams, calculate the following dimensions: A = 26'- 4" (given on the framing plan drawing) C = (tw /2) + 1/16 = 1/4 + 1/16 (The (tw /2) value is taken from the W18 x 60 beam not the W12 x 35) E = 1/2 B = (A - (C1 + C2)) = 26'-4" - (5/16 +5/16) = 26' - 3 3/8" D = B - (E1 + E2) = (26'-3 3/8") - (1/2 + 1/2) = 26' - 2 3/8"

  5. Cope Cuts When the tops of beams are to be flushed, a notch must be cut into the connecting beam to prevent interference with the flange of the other beam. Such a notch is called a cope, block, or cut. It is the practice of the structural detailer to draw the depth dimension to scale so that the relation of the detail is correct and so the fabricator can interpret the relation of the holes to bolts or other holes more readily. Q1 = k distance This is a minimum dimension. Q1 can never be smaller than the k-distance Q2 = ((bf - tw) 2) + 1/2 The Q2 dimension is measured from the back of the connection angle Note: Q1 and Q2 are rounded to the nearest 1/4"

  6. Cope Cuts The intersection of the horizontal and vertical cuts (re-entrant cut) is shaped to a smooth radius to provide a fillet at this point. Although most shops routinely provide these fillets, they should always be shown on shop details. An approximate minimum radius to which this corner must be shaped is 1/2 inch (13th Edition AISC manual, Part 9). Q1 = k distance This is a minimum dimension. Q1 can never be smaller than the k-distance Q2 = ((bf - tw)/ 2) + 1/2 The Q2 dimension is measured from the back of the connection angle Note: Q1 and Q2 are rounded to the nearest 1/4"
