| dc.title | The parametric study of tall building fire resulting in a collapse | en_US |
| dcterms.abstract | Since the severe casualties of tall building collapse induced by fire, the research of tall building fire failure mechanisms is becoming popular these years. Study about the mechanisms of fire-induced collapse helps to learn what happened with the structural elements in the whole fire process and these theoretical principles are the prerequisites of fire-protected applications. Aparametric study is a fundamental method to learn the mechanisms of fire resulting in collapse. Concerning the localized failure resulting in a broader collapse, this project focus on the one-storey fire structure. This project defined eight parameters and used two ways to compare their impact on the collapse mechanisms. The first one is to calculate the pull-in force related to collapse, and the second one is to simulate the collapse temperature. The pull-in force and the collapse temperature can be seen as two essential factors associated with the whole structure collapse. A larger pull-in force indicates the beam is stronger, and lower collapse temperature implies the structure is more vulnerable to fire and result in collapse. The results of the calculation of the pull-in force show that only increasing the universal column size leads to a smaller pull-in force, which results in a weaker beam. Increasing other parameters all lead to a stronger beam. And the simulation results indicate a similar finding-only increasing the UC size sparks off a higher collapse temperature, making the structure harder to collapse. And length of the beam, uniformly distributed load and universal column size are the key parameters resulting in a collapse of the tall building fire. | en_US |
