  2. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/Reinforced_Concrete_Column

    A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.

  3. Slenderness ratio - Wikipedia

    en.wikipedia.org/wiki/Slenderness_ratio

    111 West 57th Street in Midtown Manhattan is the world's most slender skyscraper. In architecture, the slenderness ratio, or simply slenderness, is an aspect ratio, the quotient between the height and the width of a building. In structural engineering, slenderness is used to calculate the propensity of a column to buckle.

  4. Johnson's parabolic formula - Wikipedia

    en.wikipedia.org/wiki/Johnson's_parabolic_formula

    The slenderness ratio is an indicator of the specimen's resistance to bending and buckling, due to its length and cross section. If the slenderness ratio is less than the critical slenderness ratio, the column is considered to be a short column. In these cases, the Johnson parabola is more applicable than the Euler formula.

    Lally column – is a round thin-walled structural steel column oriented vertically to provide support to beams or timbers stretching over long spans. The steel shell of a Lally column is filled with concrete. Lightening holes – Limit load (physics) – Limit state design – Linear elasticity – Lintel – Live load – Load bearing ...

    Fig. 1: Critical stress vs slenderness ratio for steel, for E = 200 GPa, yield strength = 240 MPa. Euler's critical load or Euler's buckling load is the compressive load at which a slender column will suddenly bend or buckle. It is given by the formula: [1] = where

  7. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    If the ratio is greater than 10, it is considered a long column (sometimes referred to as a slender column). Timber columns may be classified as short columns if the ratio of the length to least dimension of the cross section is equal to or less than 10. The dividing line between intermediate and long timber columns cannot be readily evaluated.

  9. Column - Wikipedia

    en.wikipedia.org/wiki/Column

    The term column applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, [1] which is made of stone, or appearing to be so. A small wooden or metal support is typically called a post. Supports with a rectangular or other non-round section are usually called piers.
