Question
How can different floor diaphragms be assigned in a MIDAS Gen model that consists of two towers and a shared podium?
Answer
To assign different floor diaphragms in a structure with two towers and a common podium/base, modules must be defined for each tower. This allows diaphragms to be applied individually to different vertical zones.
Step-by-Step Procedure:
- Define Modules:
# Navigate to: Structure > Control Data > Define Module
# Define separate modules for each tower.
- Set Diaphragm Assignment:
After modules are defined, diaphragms can be assigned or ignored for each story within each module. This enables independent diaphragm behavior for each tower.
- Review Module Data:
Ensure each module is correctly defined with the display name and number of stories. Refer to the module data table in the interface for verification.
Important Notes When Defining Modules:
- No Story Overlap: A single story must not belong to multiple modules.
- Module Continuity: Members in one module must not be interrupted by members from another module.
- Podium/Base Module: The shared base (podium) must be defined as the base module. Only the tower portions should be separated as individual modules.
