Fire Performance of Reinforced Concrete Columns

open access: yes, 1985
To develop general methods for the prediction of the fire resistance of reinforced concrete columns, experimental and theoretical studies were carried out. Results obtained in the first phase of the study, which involved the testing of twelve columns, are given. Of the variables studied in this phase, load, cross-section size, and type of aggregate had
