Strains of Concrete in RC Structures Subjected to Fire

Structural analysis of reinforced concrete chimneys subjected to uncontrolled fire

We studied the behavior and residual structural capacity of reinforced concrete chimneys subjected to an uncontrolled fire. We used a combination of a heat transfer finite element model – to obtain the temporal distributions of temperature during the fire event – and the structural model of concrete chimney design provided by the American Concrete Institute (ACI 307–08). This approach allows es...

Reliability of Existing Concrete Structures during Fire – the Case Study of Concrete Slabs Subjected to Chloride Induced Corrosion

The assessment of the reliability of concrete structures during fire is becoming increasingly important due to the emergence of performance based design codes, the increased interest in decision making with respect to life time optimization of infrastructure, and the direct applicability of reliability calculations for insurance purposes. Most recent studies on the topic of the probabilistic ca...

Extracting Concrete Thermal Characteristics from Temperature Time History of RC Column Exposed to Standard Fire

A numerical method to identify thermal conductivity from time history of one-dimensional temperature variations in thermal unsteady-state is proposed. The numerical method considers the change of specific heat and thermal conductivity with respect to temperature. Fire test of reinforced concrete (RC) columns was conducted using a standard fire to obtain time history of temperature variations in...
