Analysis of Truss Frames by Method of the Stiffness Matrix.

摘要

The development of the general stiffness coefficients and load constants are presented for the flat Pratt and gabled Pratt truss frames. The stiffness coefficients and load constants are derived through the application of the theorem of least work. The elemental stiffness matrices for the flat and gabled Pratt truss frames are assembled using the respective stiffness coefficients for each type of truss. Two examples illustrate the procedures for computing numerical solutions for each type of truss frame.
