Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.

Question

A column is built up from 4-300 mm x 16 mm
plates, welded to form a box section having a
width of 300 mm along the x-axis and a depth of
332 mm along the y-axis. Unbraced column
length with respect to the x-axis is 12 m.
With respect to the y-axis, the column is braced
at third points so that the unbraced length is 4 m.
Assume pinned-ends for both axis. Sidesway is
prevented. Steel yield stress: Fy = 248 MPa
Modulus of elasticity = 200 GPa
1. Compute the effective slenderness ratio with
respect to the x-axis.
2. Compute the effective slenderness ratio with
respect to y-axis.
3. Compute the axial load capacity (kN) of the
built up column.
