[abstract]
A generic fiber model algorithm for the analysis of cross sections under biaxial bending and axial load is presented. The method is applied to any cross section (reinforced, composite, repaired etc.) of irregular shape with/without openings and consisting of various materials. The only assumption is that plane sections before bending remain plain after bending (Bernoulli – Euler assumption). The cross section is described by polygons and circles. The material properties are user – defined. The stress – strain diagrams of all materials are composed of any number and any combination of consecutive parabolic or linear parts, subject to a desired accuracy. Various effects such as concrete confinement, concrete tensile strength, strain hardening of the reinforcement etc. may be taken into account, allowing full control of the designer over the entire model. A special purpose computer program with full graphical interface has been developed the main features of which are illustrated in a number of examples.
