Basic Beam Element Review

Loads and Boundary Conditions

2-D Horizontal Frame (rod and beam elements added)

2-D Horizontal Beam Example:

What about truss/frame elements that are not horizontal, then we rotate the stiffness matrix.

To get the element Stiffness Matrix Ke one can use MathCad, MatLab, Maple or do it by hand.

When we join the elements of a frame, it is like adding axial or rotational stiffness. Let’s go over some examples…8.9a, 8.10, use Frame2d
