Identify stiffened and unstiffened plate elements in Stiffened - a projecting piece of steel whose two edges parallel to the direction
compression. of a compression force are supported
Unstiffened - a projecting piece of steel having one free edge parallel to the
direction of a compression force, with the other edge in that direction
unsupported
Describe local buckling and compactness within the Local buckling - localized plate instability
context of columns. One element (web, flange, leg, stem) buckles before global buckling occurs
Compactness - if λ ≤ λr for all elements no local buckling
Explain the effect of local buckling on design strength. May reduce design strength
Describe the behavior of a built-up compression Double angle buckles flexural about the x-axis
member. Double angle buckles flex-tors about the y-axis
Single angle buckles between connectors about the z-axis
Sufficient connectors prevent buckling about the z-axis

Explain why a column base plate is required to transmit It distributes loads from the column to concrete footing; it is necessary for the
axial force from a steel column to a concrete footing. column load to be spread over a sufficient area to keep the footing from being
overstressed. Loads for the steel column are transferred through a steel base
plate to a fairly large area of the footing below.
Explain structural difference between beams and girders -Beams
with respect to load and bracing. Continuous bracing, includes the dead loads, live loads, and self weight
-Girders
Discrete bracing, includes the reactions of the beams and self weight
Describe various stages in flexural response leading up -When beam is resisting moment at each point
to the ultimate beam capacity, the fully plastic moment -Load increases 🡪 outer fiber of flanges begin to yield 🡪 yielding moves through
flanges into first fibers of the web 🡪 yielding occurs across entire cross section
Define and determine the fully plastic moment, Mp The moment that will produce full plasticity in a member cross section and create
a plastic hinge
Mp=FyZx
Determine if member is compact If no local buckling occurs
