Plane Frames



Structural analysis using the matrix stiffness method for structures modeled as beams has been presented in the preceding two chapters. This method of analysis when applied to structures modeled as plane frames with loads applied in the plane of the frame, requires the inclusion of the axial effect in the element stiffness matrices; hence, the inclusion of axial effect in the system stiffness matrix. The analysis also requires a coordinate transformation of element end forces and displacements from element or local coordinate axes to the system or global coordinate axes. Except for the consideration of the axial effect and the need to transform the element end forces and displacements, the matrix stiffness method when applied to plane frames is identical to the analysis of beams presented in Chapters 1 and 2.
