Should I solve dilated structures in a single project or in separate projects?
You can solve dilatation projects in a single project in the program. During the solution, the program will automatically find dilatations depending on the slab integrity you entered.
You need to examine the state and geometry of your building in order to enter it as single or separate projects. Let's examine possible assumptions about different geometries with examples:
Buildings that continue as a single block on the lower stories and as independent towers on the upper stories
In such structures, you do not have the chance to solve them as different projects. Therefore, you have to solve the project according to more than one rigid diaphragm acceptance in stories.
Common foundations
Structures with dilated foundations
The most suitable method for solving these types of structures is to model the building as different projects.
