Abstract
The paper presents the basic steps leading to the derivation of the stiffness and
mass matrices for the new dynamic finite element for beam-type slender
elements with transverse crack. It further discusses its implementation in the
dynamical analysis of cracked frame structures. Although the basic idea of the
paper is devoted to cracks, the application can also be utilised for the modelling
of other local stiffness reductions or plastically deformed parts of structures, as
for example plastic hinges.
1 Introduction
Despite careful design, cracks or other types of local stiffness reductions might
appear on a structure during its utilisation. Although a crack or another local
weakness of a structural member does not mean that the structure will collapse,
it is especi
