CALEB is a nonlinear finite element program for geometric and material nonlinear analysis of offshore platforms and general framed structures. The finite element formulations implemented in CALEB assumes large displacements and small strain. Geometric nonlinearity is taken into account by means of an updated Lagrangian formulation. Material nonlinearity is taken into account by means of an elastic perfectly plastic model derived from plastic hinge theory. Capabilities of CALEB version 1.4, the current release of CALEB, include: pre-processor for mesh refinement, problem-oriented language input, distributed member loads, automatic generation of environmental loads, joint failure check, save/restart procedure, eigenvalue buckling analysis, nonlinear stress analysis, and graphical post-processing. In this paper a brief description of CALEB version 1.4 and of its main features is presented.
