nccer 27105 - floor systems 47min how should the joints be positioned when installing a built - up beam? at 8 intervals directly over support columns midway between support columns as close to the span midpoint as possible

Explanation:

When installing a built - up beam, the joints should be positioned directly over support columns. This placement helps in effectively transferring the load from the beam to the columns, ensuring structural integrity. Positioning joints at 8' intervals may not align with the structural support requirements. Midway between support columns or as close to the span midpoint as possible would not be ideal as these positions do not provide the necessary support for the joint.

Answer:

directly over support columns
