Plane Frame and Grid Equations
Many structures, such as buildings and bridges, are
composed of frames and/or grids.
This chapter develops the equations and methods for solution
of plane frame

Chapter 4 - Development of Beam Equations - Part 2
Beam Stiffness
General Formulation
We can account for the distributed loads or concentrated loads
acting on beam elements by considering the following
formulation for a general structure:
F =

Development of Truss Equations
Having set forth the foundation on which the direct stiffness
method is based, we will now derive the stiffness matrix for
a linear-elastic bar (or truss) element using

Introduction
We begin this chapter by developing the stiffness matrix for the bending of a beam
element, the most common of all structural elements as evidenced by its prominence
in buildings, bridges, towers, and m
