Abstract

In the preceding chapters, we have considered the matrix analysis of structures modeled as beams, frames, or trusses. The elements of all these types of structures are described by a single coordinate along their longitudinal axis. These are structures with unidirectional elements, called skeletal structures. In general, they consist of individual members or elements connected at points designated as nodes or joints. For these types of structures, the behavior of each element is considered independently through the calculation of the element stiffness matrices. The element stiffness matrices are then assembled into the system stiffness matrix in such a way that the equilibrium offerees and the compatibility of displacements are satisfied at each nodal point. The analysis of such structures is commonly known as the Matrix Structural Analysis and could be applied equally to static and dynamic problems.
