Learning summary Columns: -
slender members that transfer axil compressive loads Can be either long or short and are chosen depending on, what they will be used for, practicality and what their cross sectional strength can handle
Week 5 Wall systems
Structural Frames

Steel:
less common seen on sloping sites traditional framing need bracing or rigid joints in corners to stabilise structure
Concrete - Seen in larger scale buildings (city) - Combination of columns connected to beams - Columns have to be strong enough to carry live and dead loads above
Figure 1(network steel, 2011)
The above cross sectional column examples are the three most common due to their similar properties of being material and cost efficient. For example Circular columns are chosen over a solid long columns as they have a greater outer radius and strength against buckling (Chitale, Gupta, 2007, p.72).

used when the fire rating is low common in industrial buildings usually a grid of columns such as RHS, UB, CHS and SHS (examples in column section) connected to beams and girders steel frames have to be stabilised though either bracing, shear wall bracing or by making the joints rigid (Newton, 2014)

Load bearing walls Load bearing walls are under compression and therefor need suitable materials such as -
