Dynamic Analysis of Plane Frames

Abstract

The dynamic analysis using the stiffness matrix method for structures modeled as beams was presented in Chapter 14. This method of analysis when applied to beams requires the calculation of element matrices (stiffness, mass, and damping matrices), the assemblage from these matrices of the corresponding system matrices, the formation of the force vector, and the solution of the resultant equations of motion. These equations, as we have seen, may be solved in general by the modal superposition method or by numerical integra­tion of the differential equations of motion. In this chapter and in the following chapters, the dynamic analysis of structures modeled as frames is presented.
