Diaphragm Required Strength per ACI 318-19 with ideCAD

How does ideCAD calculate diaphragm required strength according to ACI 318-19?


  • Rigid and semi-rigid diaphram conditions should be choosen by user according to irregularities defined in ASCE 7/16.

  • Analysis is done automatically according to finite element method.


The required strength is designed to analyze https://idecad.atlassian.net/wiki/spaces/IKP/pages/1539605249. It’s important to determine the required strength of diaphragms to control the effects of out-of-plane loads simultaneously with other applicable loads.

Diaphram modeling and analysis

The analysis is done automatically according to the finite element method. Rigid and semi-rigid diaphragm conditions should be chosen by the user according to ASCE 7/16.
