ROBUSTNESS AND CONSEQUENCE BASED ASSESSMENT OF AN EXISTING DAM


== Abstract ==

<p>Robustness plays a relevant role in the capacity of a structure to sustain abnormal loads<br>
or to deal with unexpected events with large effects, such as explosions and terroristic<br>
attacks. Such situations on dams may have extremely large consequences. For buildings,<br>
the design approach that best implements robustness concepts is represented by the so<br>
called &ldquo;Consequence Based Design&rdquo;: even if nothing is known about the cause, selective<br>
element removals and extreme load on the structure are modeled, and their effects are<br>
determined with respect to progressive collapse and damage arrest.<br>
In the paper we try to set-up a &ldquo;Consequence Based Assessment&rdquo; of a typical example of<br>
a gravity dam built between the &lsquo;30s and &lsquo;40s of the last century in the northwestern<br>
Italian Alps. A simplified model of the structure is adopted. Removal of parts of the dam<br>
cross-section is assumed to occur: the effects of the extent of damage is discussed on the<br>
bases of the tension generated within the body of the dam.</p>
