Two-Way Slab Required Strength.

Rigid and semi-rigid diaphram conditions should be choosen by user according to irregularities defined in Codes.

Analysis is done automatically according to finite element method.

Required strength is designed to analyse with Load Factors and Combinations

Symbols in ACI 318-19

Mu = factored flexural moment at section, lb
Mn = nominal flexural strength at section, in.-lb
Vn = nominal shear strength, lb
Vu = factored shear force at section, lb
