What is the difference between buckling and crippling?
Buckling Load: It is the highest load at which the column will buckle.
Crippling Load: It is the max load beyond that load, it cant use further it becpomes disable to use.
The buckling Load < The Crippling Load
Safety load= Crippling Load/ Factor of safety
Main difference between local and overall buckling related to distortion of the overall system geometry. Local buckling does not cause distortion of the overall geometry, usually local buckling seems on short (channel or angle) compression members (excessive loaded and material related problem). On the other hand overall buckling causes distortion, we can give example as plastic ruler compressed by fingers . There is equation on buckling developed by Euler.
Buckling and bending are similar in that they both involve bending moments. In bending these moments are substantially independent of the resulting deflections, whereas in buckling the moments and deflections are mutually inter-dependent - so moments, deflections and stresses are not proportional to loads.

The elastic bucklingoccursfor slender columns that have a large slenderness parameter(KL/R) before any yielding in the materials. While the inelastic buckling occurs for intermediate columns that have amoderate(KL/r) ratio and the failure occurs by both the buckling and part of the materials yieldingsimultaneously
Generally local bucking occures in large web beams under heavy concentrated load while the lateral buckling occures in long slender columns. lateral buckling is more dangerous than the local buckling as the structure may collapse due to lateral collapse of the column. local buckling can be controlled by providing web stiffners while the lateral buckling can be prevented by controllinge the slenderness ratio.
buckling means that when a member of a building subjecting to point load or external load along it's axis then buckling occurs. binding biding meaning is that when we pack together two material more closly. like when we add water to cement then between them a reaction occures after that there is formed a strong bond between them by this example we define binding.
