Sensitivity of the seismic response to the modelling variables defining constitutive models of reinforced concrete frames (2023)
Conference Proceeding
Karaki, G. (2023). Sensitivity of the seismic response to the modelling variables defining constitutive models of reinforced concrete frames. In Life-Cycle of Structures and Infrastructure Systems. https://doi.org/10.1201/9781003323020

Probabilistic performance-based methods are well integrated into earthquake engineering applications. Therefore, the seismic response uncertainty and its sources must be adequately characterized for a more reliable seismic assessment. The paper exami...

Probabilistic approaches provide a more realistic look into assessing structures under fire conditions and overcome some limitations observed in the more traditional (deterministic) approaches. These approaches have also been introduced to the fire e...

Enhancing fire resistance of reinforced concrete beams through sacrificial reinforcement (2022)
Journal Article
Hostetter, H., Naser, M. Z., Hawileh, R. A., Karaki, G., & Zhou, H. (2022). Enhancing fire resistance of reinforced concrete beams through sacrificial reinforcement. Architecture, Structures and Construction, 2(2), 311-322. https://doi.org/10.1007/s44150-022-00061-w

Due to the superior properties of concrete, structural members made of concrete often satisfy fire requirements specified in codes and standards without special installations or the use of external insulation. A closer examination into fire codal pro... Read More about Enhancing fire resistance of reinforced concrete beams through sacrificial reinforcement.

Generalized temperature-dependent material models for compressive strength of masonry using fire tests, statistical methods and artificial intelligence (2022)
Journal Article

Architecture, Structures and Construction, 2(2), 223-229. https://doi.org/10.1007/s44150-021-00019-4

Masonry has superior fire resistance properties stemming from its inert characteristics, and slow degradation of mechanical properties. However, once exposed to fire conditions, masonry undergoes a series of physio-chemical changes. Such changes are...
