Cross04

This is a MATLAB program for solving a continuous beam using the Cross Process. Euler-Bernoulli flexural behavior is assumed (Navier beam theory).

This program implements the Cross Process for continuous beams with uniformly distributed loads in each spam.

For more details of this process, refer to the book "Análise de Estruturas: Conceitos e Métodos Básicos", Second Edition, by Luiz Fernando Martha, Elsevier, 2017.

@version 1.03

Initial version 1.00: September 2026

Initially prepared for version Cross01 application of course CIV 2801 - Fundamentos de Computação Gráfica, 2026, second term, Department of Civil Engineering, PUC-Rio. Cross01 version has no canvas and controls the continuous beam Cross solution through control buttons.

Version 1.01: September 2026

Cross02 version: added model canvas and display of continuous beam model.

Version 1.02: October 2026

Cross03 version: implementation of drawing of deformed configuration and bending moment diagram.

Version 1.03: October 2026

Cross04 version: Implementation of procedures that treat mouse events for insertion of an internal support, deletion of an internal support, balancing of the bending moment at a selected internal node, modification of the value of a uniform load of a member, and modification of the position of a node.
