Structural Capacity of Reinforced Concrete Columns Subjected to Fire Induced Thermal Gradients.

摘要

Based on prescribed fire time-temperature conditions the response of planar reinforced concrete frame structures was obtained at selected time intervals in terms of temperature distributions,forces,moments and displacements. Temperature dependent thermal and mechanical material properties as well as creep,shrinkage,tensile cracking and crushing were considered in this analysis. The behavior was described in terms of forces,stresses,strains and displacements. (Modified author abstract)
