CALEB: A COMPUTER PROGRAM FOR GEOMETRIC
AND MATERIAL NONLINEAR ANALYSIS OF
OFFSHORE PLATFORMS AND GENERAL FRAMED
STRUCTURES

Abstract
- 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,
eigenva
