Basic Theory,ural behaviour is linear elastic and that any non-linear part of the relationship between load and structural displacements may be disregarded. It is taken for granted that the load direction throughout the entire span of the structure is perpendicular to the axis in the direction of its span.

One and Two Degree of Freedom Systems,more realistic cases of including the effects of damping and the possibility of an external fluctuating force. However, in this chapter we limit ourselves to only consider the cases of single or two degrees of freedom systems, subject to a single harmonic force. Such a load case is virtually absent

The Finite Element Method in Dynamics,hods usually applied elsewhere in theory of elasticity. However, in dynamics it is necessary to add the effects of mass in motion as well as internal damping, which, for a line like system, will affect the shape of motion into a combination of harmonic and hyperbolic functions, see Chapter 3, and th

Frequency and Time Domain Response Calculations,in Chapters 4 with respect to the original degrees of freedom (see Eq. 4.39) and in Chapter 5 with respect to the modal degrees of freedom (see Eq. 5.13 for a discrete system description and Eq. 5.32 for a continuous system description). In this chapter we shall present possible solution strategies.

Dynamic Response to Earthquake Excitation,to representative single component horizontal ground acceleration will usually suffice for design purposes. The problem of dynamic response calculations under such excitation is pursued in the present chapter. For simplicity, the focus of the theory below is limited to structures with main extension

Wind Induced Dynamic Response Calculations, its span. The wind velocity vector is split into three fluctuating orthogonal components, . in the main wind direction, and . and . in the across wind horizontal and vertical directions. Typical full scale recordings of ., . and . are illustrated in Figs. 8.1 and 8.2 above.

Moving Loads on Beams, though the problem may not necessarily be that of the bridge, it may also involve uncomfortable vertical oscillations of the vehicle. The problem may also occur on moving hoisting forces on heavy cranes.
