| Summary: | The
behavior of buildings during fires has recently become a significant issue.
Analyzing structures at elevated temperatures is complex and challenging in
structural engineering as engineers must take into consideration factors that
may not be included at ambient temperatures, namely material and geometric
non-linearity as well as time-temperature-varying strength. In this study, the
finite element software ABAQUS was applied to model and simulate the behavior
of structures in fire events. Steel beams and columns were modeled using
two-node linear beam elements, while concrete slabs were discretized using
shell elements. A series of verification analyses were conducted to ensure that
the analysis produced an acceptable level of accuracy. Furthermore, an
extensive sensitivity study was carried out to obtain the appropriate modeling
parameters to be used in subsequent numerical analyses. |
