GNU Octave scripts for the arc-length method. This implementation is based on a novel a extrapolated predictor.

The main script is main_arclength.m. The input files are prepared and tested. Uncomment the corresponding line in the main file to run the script for a particular problem.

Some load-displacement curves computed with this code.

• Lee frame

• 215-degree circular arch

• Semi-circular arch with asymmetric loading
