== Abstract ==<br />
<br />
<p><span style="font-size: 12.8px; font-style: normal; font-weight: 400;">This thesis is divided into two parts: in the first part the collapse of the WTC1, WTC 2 (Twin Towers) and WTC 7 buildings following the terrorist attacks of 11 September 2001 is analysed. In the second part, the collapse type and strength of frame buildings with different topological characteristics. What links the two parts is structural robustness.</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Below is an overview of the work with a description of the topic covered in each Chapter.</span><br style="font-size: 12.8px;"><br />

<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 2: timeline of the terrorist events of September 11, 2001.</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 3: description of the types of fire, the performance of structures and the behavior of the main building materials (steel, concrete) to fire.</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 4: analysis of the main hypotheses of the collapse of the Twin Towers present in the literature.</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 5: definition of structural robustness, structural toughness, vulnerability. Description of project strategies to prevent progressive collapses.</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 6: measurement of the structural strength of buildings with a reinforced concrete frame structure. through Discrete Element simulations (DEM).</span><br style="font-size: 12.8px;"><br />
<span style="font-size: 12.8px; font-style: normal; font-weight: 400;">Chapter 7: discussion of progressive collapse due to impacts from an analytical and bibliographical point of view.</span></p><br />
