  2. Compression member - Wikipedia

    en.wikipedia.org/wiki/Compression_member

    A compression member is a structural element that primarily resists forces, which act to shorten or compress the member along its length. Commonly found in engineering and architectural structures, such as columns , struts , and braces, compression members are designed to withstand loads that push or press on them without buckling or failing.

  3. Euler's critical load - Wikipedia

    en.wikipedia.org/wiki/Euler's_critical_load

    Fig. 2: Column effective length factors for Euler's critical load. In practical design, it is recommended to increase the factors as shown above. The following assumptions are made while deriving Euler's formula: [3] The material of the column is homogeneous and isotropic. The compressive load on the column is axial only.

  4. Column - Wikipedia

    In other words, a column is a compression member. ... and KL = effective length (length of an equivalent hinged-hinged column). From Equation (2) it can be noted that ...

  5. Wood method - Wikipedia

    en.wikipedia.org/wiki/Wood_method

    The Wood method, also known as the Merchant–Rankine–Wood method, is a structural analysis method which was developed to determine estimates for the effective buckling length of a compressed member included in a building frames, both in sway and a non-sway buckling modes. [1] [2] It is named after R. H. Wood.

  7. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    The duration of compression at the impact end is the time required for a stress wave to travel along the column to the other (free) end and back down as a relief wave. Maximum buckling occurs near the impact end at a wavelength much shorter than the length of the rod, and at a stress many times the buckling stress of a statically loaded column.

  8. Johnson's parabolic formula - Wikipedia

    en.wikipedia.org/wiki/Johnson's_parabolic_formula

    (L is the original length of the specimen before the force was applied.) However, certain geometries are not accurately represented by the Euler formula. One of the variables in the above equation that reflects the geometry of the specimen is the slenderness ratio, which is the column's length divided by the radius of gyration. [4]

  9. Slenderness ratio - Wikipedia

    en.wikipedia.org/wiki/Slenderness_ratio

    The effective length is calculated from the actual length of the member considering the rotational and relative translational boundary conditions at the ends. Slenderness captures the influence on buckling of all the geometric aspects of the column, namely its length, area, and second moment of area .
