Wall is exposed to wind pressure and it supports eccentric gravity loads. R ÿ 1 ã 2 c2. Second moment of area of beam ab = (0.3 × 0.6 3 )/12 = 0.0054 m 4. The enercalc concrete slender wall program uses basic principles of structural mechanics to model the wall as a series of beam segments. Aci e702 example.
