steel Flashcards
a straight structural member subjected to compressive axial loads.
Columns
Modes of Failures of columns
Crushing
Buckling
often called the “squash load”, the load at which the entire cross section would yield
Crushing
Sudden large lateral deformation of a structure due to a slight increase of an existing load.
Buckling
Critical buckling load
Pcr
Types of Column
Short
Long
Type of column where crushing failure governs
Short Column
Type of column where buckling failure governs
Long Column
Minimum axial compressive load for which a column will experience lateral instability failure or buckling
Pcr
is the smallest value of P that will cause the column to buckle
Critical buckling load
Critical buckling load is also known as
Euler buckling load (Pcr or Pe)
If the support restrict translation, K is always
less than or equal to 1
If translation is allowed, K is
always greater than 1
are supported along only one edge parallel to the direction of the load.
Unstiffened Elements
are supported along both edges parallel to the direction of the load.
Stiffened Elements
