Question

My name is Nadalie, nice to meet you, please explain Truss and Frames to me <3

Answer 1

Frame and Truss structures are designed to transfer loads from loading points to support points.

Truss

In a truss, the joints are of pin type, where end of the members can rotate freely. Moreover, individual truss members should not directly loaded transversely; loads should be applied at the joints of members so that no bending or shear forces will be generated on truss members. Self-weight of the members should be dumped both end for the same reason.

Frame

Unlike truss, the members of frames are connected rigidly at joints, and individual members can carry transverse load, which may generate bending moment, shear forces along with axial forces.

Answer 2

I am confused, what are pin type joints

Answer 3

Joints that could rotate freely if not held in place by other members.

Answer 4

rotate in what dof

Answer 5

okay so i mostly see 2D pics of these things
