Two-Way Slab Required Strength per ACI 318-19 with ideCAD

How does ideCAD calculate two-way slab required and design 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.

Required strength is designed to analyse with https://idecad.atlassian.net/wiki/spaces/IKP/pages/1539605249

M_u= factored flexural moment at section, lb
M_n= nominal flexural strength at section, in.-lb

Dimensions c₁, c_2, and l_n are based on an effective support area for a slab system supported by columns or walls. A column strip is a design strip with a width on each side of a column centerline equal to the lesser of 0.25l₂ and 0.25l₁ according to 8.4.1.4.

Factored moment

M_u at the support is calculated at the face of support for slabs built integrally with supports.
