Abstract: The bearing performance of one SRC cantilever girder is studied through fine finite element analysis, focusing on the steel web palates contribution to the shear bearing capacity and ultimate bearing capacity of this girder. And then the complementary explanation is given out for the application of calculation formula for shear bearing capacity in current code. At last some factors which have be paid attention to in the simplified model is discussed.
Keywords: steel reinforced concrete; crack; shear bearing capacity; ultimate bearing capacity
