Title: Fire Response of Prestressed Concrete Members
Author(s): Boris Bresler and Robert H. Iding
Publication: Special Publication
Appears on pages(s): 69-114
Keywords: beams (supports); computer programs; concrete slabs;
fire resistance; fire tests; prestressed concrete; structural
analysis; thermal gradient; thermal stresses.
Abstract:The thermal and structural responses of prestressed concrete elements under ASTM E-119 fire test exposure were studied analytically. Comparisons of analytical results with experimentally recorded local temperatures and deflections for specimens tested by the Portland Cement Association showed good agreement. In addition, stress histories in concrete and in steel tendons and extent of cracking in concrete during the fire test exposures were determined analytically. Sensitivities in material characterization at elevated temperatures and other modeling uncertainties are discussed.
