CALCULATION METHODS FOR ULTIMATE MOMENT CAPACITY OF SRC COLUMNS WITH T-SHAPED STEEL

The calculation method forbearing capacity of concrete columns reinforced with I-shaped steel ismodified for SRC columns reinforced with T-shaped steel and their mechanicalproperties and failure modes are analyzed. Combining with thecurrent national codes, the calculation methods and formulas of ultimatemoment capacity of this kind of columns are proposed and heights of the concretepressured region in two situations are compared. The bearing capacity ofone SRC column with T-shaped steel is checked using above formulasand the results agree well with the experimental data, andthis numerical example shows that the suggested method has a good precision.
