Walls in ACI318 Walls in ACI318 melsawaf (Structural) (OP) 1 Jun 15 05:45 Dears - Is there any provisions for vertical members whether to consider it wall or column ?? i mean ratio of height to width or length ?? RE: Walls in ACI318 Trenno (Structural) 1 Jun 15 10:55 Usual rule of thumb is a ratio of 4:1, anything beyond being reasonably designed as a wall. When it is touch and go though, it's a good idea to check what capacity you get if it were designed as a column. However I have no clue what the American code says. RE: Walls in ACI318 melsawaf (Structural) (OP) 1 Jun 15 14:31 i believe that 4:1 ratio is mentioned in BS code in the Egyptian code the ratio is 5:1 RE: Walls in ACI318 JedClampett (Structural) 4 Jun 15 01:18 ACI in definitions says a column is 3:1 with the smaller side being the least lateral dimension. But it explains that any member used to carry predominately a compressive load is a column. RE: Walls in ACI318 TXStructural (Structural) 4 Jun 15 04:04 From the horses mouth. Quote (ACi 318-14)Wall—a vertical element designed to resist axial load, lateral load, or both, with a horizontal length-to-thickness ratio greater than 3, used to enclose or separate spaces.
