Individual sloping and vertical pieces connecting the chords are called web members, and the whole assembly of these pieces is called the web. At panel points, where the individual pieces intersect, the pieces are connected by bolts, rivets, or welds.

The framing carried by a truss generally is designed so that loads bear on the truss at the intersections of a chord and web member. As a result, the chord and web members are subjected only to tension or compression, and thus less material can be used than what is needed when the truss members also have to resist bending.

Three of the better-known types of trusses (all patented in the 1840's) are the Howe truss, named after the American engineer William Howe; the Pratt truss, named after the American engineer Thomas Pratt; and the Warren truss, named after the British engineer James Warren.
