https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/98562/delete-member-commandI am trying to simulate a demolition sequence for a large hangar. The demolition sequence will involve removing steel members in a particular sequence. I have to monitor the stresses in the members to remain at the end of each stage of the removal.

So essentially you will have the first analysis with the full model and then separate analysis models for each subsequent stage.</p> <p>DELETE member cannot be used for a scenario where you start with the full model and deactivate members in installments. DELETE member is typically used when you need to model the entire structure for completeness of the model but do not need to consider some of these for analysis purpose. For example some non- structural components like ladders, handrails, architectural elements, attachments etc.</p><div style="clear:both;"></div>
