A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members.

What does "vertical member" mean here? Is hanging beam a type of such vertical members?

A beam is a Horizontal member, it transfers the load to the vertical members such as wall studs or posts.

When you lay down on a bed or on the floor you are the horizontal position, When you are standing on your feet you are in the vertical position.


  • I like the clarification of “standing” is vertical.

Beams and joists span horizontally to transfer load to vertical members like posts and load-bearing studs, which eventually bear down on footings or slabs or otherwise down to the ground.
