Modern Structural Analysis<br />
The modern use <strong>of</strong> <strong>non</strong><strong>linear</strong> <strong>analysis</strong> focuses mostly on these three<br />
fields:<br />
‣ Complex / stringent safety requirement structures (e.g. nuclear plants,<br />
dams, bridges)<br />
‣ Virtual laboratory for parametric studies<br />
‣ Existing structures (evaluation, repair, rehabilitation)<br />
Three types <strong>of</strong> <strong>non</strong>-<strong>linear</strong>ities may arise:<br />
F<br />
<br />
<br />
Concrete<br />
(“code model”)<br />
Steel<br />

Geometrical<br />
