2. Euler's critical load - Wikipedia

   en.wikipedia.org/wiki/Euler's_critical_load

   The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. As the load is increased beyond the ...

3. Southwell plot - Wikipedia

   en.wikipedia.org/wiki/Southwell_plot

   The Southwell plot is a graphical method of determining experimentally a structure's critical load, without needing to subject the structure to near-critical loads. [1] The technique can be used for nondestructive testing of any structural elements that may fail by buckling. [2]

4. 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. The ...

5. Buckling - Wikipedia

   en.wikipedia.org/wiki/Buckling

   Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. . Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capac

6. Column - Wikipedia

   en.wikipedia.org/wiki/Column

   Since at this stress the slope of the material's stress-strain curve, E t (called the tangent modulus), is smaller than that below the proportional limit, the critical load at inelastic buckling is reduced. More complex formulas and procedures apply for such cases, but in its simplest form the critical buckling load formula is given as Equation ...

8. Johnson's parabolic formula - Wikipedia

   en.wikipedia.org/wiki/Johnson's_parabolic_formula

   In structural engineering, Johnson's parabolic formula is an empirically based equation for calculating the critical buckling stress of a column. The formula is based on experimental results by J. B. Johnson from around 1900 as an alternative to Euler's critical load formula under low slenderness ratio (the ratio of radius of gyration to ...

9. Structural engineering theory - Wikipedia

   1.0 x Dead Load + 1.0 x Live Load. Different load cases would be used for different loading conditions. For example, in the case of design for fire a load case of 1.0 x Dead Load + 0.8 x Live Load may be used, as it is reasonable to assume everyone has left the building if there is a fire.
