Abstract:
The recent catastrophic failure of an offshore platform brought back into question the shear design of reinforced concrete members. Specifically, there is renewed suspicion that the current design practice may be uncon servative for members without shear reinforcement when such members are subjected to shear and axial compression. This paper describes nonlin-ear- finite element analyses made to determine the shear response of the tri-cell regions of two offshore structures; regions subjected to such loading conditions. The accuracy of the finite element procedure is demonstrated by comparing its predictions with the experimental response of a series of specimens tested under varying ratios of shear-to-axial compression. It is concluded that, while current empirical code equations do not perform adequately under the conditions considered, nonlinear analyses can pro-vide reliable results.
