PLASTIC DEFORMATION CAPACITY OF H-SHAPED STEEL BEAM CONNECTED TO CONCRETE FILLED STEEL TUBULAR COLUMN

摘要：

The flexural strength of a beam web connected to a concrete filled circular steel tubular column is calculated by a mechanism method assuming the plastic collapse mechanisms of the column wall and the beam web. The flexural strength decreases as the diameter-thickness ratio of the column increases. The flexural strength of the beam web connected to the circular CFT column is greater than that of the beam web connected to the circular hollow steel tube. The simplified equation for calculating the flexural strength of the beam web is presented based on the analytical results. Further, the plastic deformation capacity of the beam connected to the square CFT column is calculated.
