Joists are connected to beams in various ways. All of them would involve some sort of hanger or strap made out of metal. Simpson Strong-Tie is a major manufacturer of these hangers or straps. I do not have their website handy, but it should not be too hard to find.

Why does upstairs shake when walking?
If your house is wood framed with wood joists, the shaking may be caused by floor joists being too small. This will cause the floor to sink whenever a person walks across the room. Floor joists should be size by an experienced carpenter, architect, or engineer to prevent movement.Another cause of floor movement may be insufficient bracing between the floor joists. This will cause sagging and twisting of the joists.There are several solutions that require the skills carpenter. New joists can be added beside the existing joists to strengthen the floor. Another option is to add one or more beams and columns in the room below the floor. Or blocking can be added between existing joists to add support.
What is the difference between a Joist and Beam?
A joist can be a board as small as a 2 x 6 on up to a 2 x 12. A "beam" can be as simple as two joists nailed together. Beams will change depending on the load required of it. Some beams will require three 2 x 12s, glued and screwed or extreme loads or spans will call for engineered wood beams or even steel "I" beams with pipe columns.

How do you make trebuchets?
In its barest form, a trebuchet is a simple Type 1 Lever - a long pole with a weight at one end, and a pivot in the middle. They are relatively simple to make - all that is needed is wood and iron. A long, straight beam of wood (or several such beams) are required for the throwing arm, with thick wood beams being used to create dual "A-frame" structures as the supports. An iron rod is typically used for the pivot, and stones or iron scraps are typically what fills the counterweight bucket.
