Sažetak
A numerical model for numerical analysis of reinforced and prestressed concrete plates and shells including creep and shrinkage of concrete, already developed by the authors, has been updated with presented nonlinear creep model for concrete. The model can be applied for all levels of concrete stresses, while its use for ultimate stress levels is still not fully tested. Presented nonlinear creep model is simple, based on the well known linear model of concrete creep, and intended for simulation of practical concrete structures. For the verification of the presented model, experimentally tested square concrete plate and cylindrical concrete shell were analysed numerically. The results of experimental tests at high stress levels and numerical results are similar. Some additional experimental tests for testing of the presented nonlinear creep model in practice and its eventual updating are planned.
