ANALYTICAL BEHAVIOUR OF CONCRETE-FILLED DOUBLE SKIN STEEL TUBULAR STUB COLUMNS AFTER EXPOSURE TO FIRE

摘要：

This paper develops a finite element model for concrete-filled double skin steel tubular stub columns after exposure to ISO-834 standard fire. Reasonable agreement is obtained between the predicted load-deformation curves and the test results. A parametric analysis is then performed to study the effects of different parameters,such as fire exposure time,section type,sectional dimension and hollow section ratio,on the column residual strength.
