2.6 Dynamic effects
Vibration can be a problem in slender bridges where the natural frequency is at a level which
can be excited by wind or traffic. Such a possibility can be investigated by means of a
dynamic analysis. In dynamics, mass has a significant effect on the response of the structure
to a given load and computer models must incorporate a representation of mass as well as
stiffness. This is frequently done by ‘lumping’ the distributed mass of a bridge at a finite
number of nodes.
