| Abstract: | The calculation method for
bearing capacity of concrete columns reinforced with I-shaped steel is
modified for SRC columns reinforced with T-shaped steel and their mechanical
properties and failure modes are analyzed. Combining with the
current national codes, the calculation methods and formulas of ultimate
moment capacity of this kind of columns are proposed and heights of the concrete
pressured region in two situations are compared. The bearing capacity of
one SRC column with T-shaped steel is checked using above formulas
and the results agree well with the experimental data, and
this numerical example shows that the suggested method has a good precision. |

| Keywords: | T-shaped steel the normal section bearing capacity the test of pressure and bending loaded loading angle energy dissipating capacity seismic-resistant behavior |
