Sažetak
The previously developed numerical model of the authors for the analysis of conventional reinforced and prestressed concrete shells under short-term and long-term loading was improved by including the effects of transverse shear stresses on the shell failure. The 9-node degenerated shell element with the layered material model through the thickness of the shell was used. The reinforcement was modelled as a separate layer. To include the effect of transverse shear stresses on the shell failure, the failure criterion for concrete and longitudinal reinforcement was defined by a relation of transverse shear stresses and normal stresses in two mutually perpendicular vertical planes. The total transverse shear bearing capacity of the shell cross-section is obtained by summing up the concrete and reinforcement contributions. The developed numerical model and appropriate software were verified based on experimental tests.
