摘要：
The fire resistance of three full-scale beam-exterior column sub-assemblage specimens, designed according to ACI 318 seismic provisions and subjected to ISO 834 fire test, is presented. Two specimens were made of Self-Compacting Concrete (SCC) and one was made of Normal Concrete (NC). Analysis based on thermal properties of materials suggested in EC2 andANSYS software was carried out to predict the temperature distribution of specimens. The specimens performed satisfactorily after subjected to three hours ISO834 fire exposure. The significant explosive spalling occurred in about 25 minutes after heating. The beam deflection at the end of heating was approximately 10 times that before heating. The interaction of deformation between beam and column is presented. In the residual strength test, two specimens failed in ductile flexural mode, while another one failed in shear after significant yielding. The predicted and measured temperature distribution of specimens is well correlated.
