The design will be considered of a 300 X 300 mm column, using grade 30 concrete. In order to distinguish between these two types, there are two important limits for slenderness ratio/index which are the lower and the upper slenderness limits. 3-1. designing to eurocode. The latter is known as column buckling. In contrast, engineers would evaluate a non-slender or short column using an elastic first order Cross-section of Column *Min. ...

Hi Guys Does anyone have any tricks for designing slender concrete columns where the Le/r ratio starts getting higher than 50. bend diameter = 4 tie for #5 and smaller ties (ACI 7.2.2), therefore minimum radius = 2 tie. Failure of a slender column is initiated either by the material failure of a section, or instability of the column as a member, depending on the level of slenderness. In place of such an analysis, an approximate design method based on a moment magnifier principle and similar to the procedure used under the AISC Offers a proposal for revising the slender column design procedures of the 1963 ACI Code. Reinforced concrete columns are classified as short columns while the slenderness effect can be neglected or slender columns where the slenderness effect has to be included in the design. Lawrence C. REFERENCES ACI Committee 318. If a column is slender, engineers must consider either an elastic second order analysis or they may analyze the column by the moment magnification procedure contained within the Building Code Requirements for Structural Concrete (ACI 318-11). analysis wherever possible or practical.

ACI 318-08 Slender Column Requirements in Sway Frames 1. Short and slender columns (Clause 3.8.1.3, BS 8110) A braced column is classified as being short if : 7. Offers a proposal for revising the slender column design procedures of the 1963 ACI Code. This is illustrated in Fig. ACI 318-08 Slender Column Requirements in Sway Frames 1. 4.4 Design of Slender Columns Design of a slender column should be based on a second-order analysis which incorporates member curvature and lateral drift effects, as well as material non-linearity and sustained load effects. An alternative approach is specified in ACI 318-05 for columns with slenderness ratios not exceeding 100. Design Braced and unbraced columns (clause 3.8.1.5, BS 8110) A column may be considered braced in a given plane if lateral stability to the structure as a whole is provided by wall or bracing or buttressing designed to resist all lateral forces in that plane.
