- Redo the elastic analysis (F9<\/kbd> or\u00a0

Some cross-sections will be more cracked than others. This will lead to a redistribution of the internal forces. Which in turn can lead to a additional cracking.![\"\"](\"https:\/\/support.buildsoft.eu\/wp-content\/uploads\/2018\/09\/ElastScheurdeStijfheid.png\")
