Dynamic Analysis of Beams inertial effect in the structure: (1) the lumped mass method in which the distributed mass is assigned to point masses, and (2) the consistent mass method in which the assignment to point masses includes rotational effects. The latter method is consistent with the static elastic deflections of the beam.

Dynamic Analysis of Plane Framese 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.

Dynamic Analysis of Gridsplane or normal to its plane, as a special case, is the immediate reduction of unknown nodal coordinates for a beam element, hence a considerable reduction in the number of unknown displacements for the structural system.

Undamped Single Degree-of-Freedom Systemertain simplified situations. For problems involving complex material properties, loading, and boundary conditions, the engineer introduces assumptions and idealizations deemed necessary to make the problem mathematically manageable but still capable of providing sufficiently approximate solutions a

Response of One-Degree-of-Freedom System to Harmonic Loadingted to forces or displacements whose magnitudes may be represented by a sine or cosine function of time. This type of excitation results in one of the most important motions in the study of mechanical vibrations as well as in applications to structural dynamics. Structures are very often subjected t

Generalized Coordinates and Rayleigh’s Methodis, structures which may be analyzed as a damped or undamped spring-mass system. Our plan in the present chapter is to discuss the conditions under which a structural system consisting of multiple interconnected rigid bodies or having distributed mass and elasticity can still be modeled as a one-deg
