Abstract:
A calculation and comparison of maximum and minimum reinforcement ratio, axial compression of normal cross section, eccentric compression capacity as well as transversal reinforcement configuration strength under combined flexure and axial forces, details of ties for RC columns were presented between Chinese Code for Design of Concrete Structures(GB 50010—2002)and American Code ACI 318M—05. Results show that firstly, for axial compression members, the strength reduction factor of American Code is smaller than that of Chinese Code; secondly, from the eccentric loaded column with tension failure to that with compression failure, the structural strength reduction factor of American Code changes with the failure mode, while that of Chinese Code does not; thirdly, for high-strength concrete, the brittleness factor is introduced to determine the nominal concrete material strength in Chinese Code, while a relatively larger stirrup reinforcement ratio is used in American Code to ensure that the failure mode of high-strength concrete is same to that of common concrete.
