Abstract (en)

The paper presents a method of non-linear analysis of load-carrying capacity and deformations of reinforced concrete columns subjected to long-term loads. Physical relationships expressing non-linear relations between internal forces and stresses, strains and stiffness are derived on the basis of the fracture and creep theories for concrete and using non-linear stress-strain diagrams modified for time effects. Second-order geometrical effects are taken into account by solving a second-order differential equation for elements subjected to compression and bending. A number of numerical and test results are presented. The technique proposed is verified by comparison of analysis results with extensive experimental data.
