| Summary: | Fire is one of the most severe conditions that can be experienced by structure during its service life, that can result in the loss of lives, property, and followed by the negative impact on the environment. As a consequence, the structure needs to be design to accommodate the load due to an increasing temperature (fire). As a result, the safety of the users who are in the building and also the environment can be met. <br />
<br />
The scope of this Final Assignment consist of study of the behavior of low storey stell structures under fire conditions, structural design at ambient temperatur (room temperature), structural analysis for determine the fire resistance ratings with fully developed fire, structural design under fire conditions, and numerical analysis to determine critical locations of the structure. <br />
<br />
The basic principle of determining the fire resistance ratings of the structure is compare the load that occurred under fire conditions with nominal capacity of each element, the nominal capacity of the elements must be greater than the load occurred. Determination of the loading effect that occurs Efi,d is determined by the time t = 0, in accordance with the load combinations that occurred under fire conditions. Nominal capacity of each element under fire conditions generally using the same procedure as used in normal circumstances, but taking into account the amount of mechanical properties changes due to increasing temperature. <br />
<br />
The final results showed that the structure has a critical time 16.991 minutes. With increasing cross-sectional dimensions of structural elements, the critical time increases up to 34.271 minutes. The use of insulation for increasing structural critical time also can be done, which generated a critical time increases significantly. |
