Local web damage can result from either intentional or unplanned events. The addition of mechanical or electrical equipment to a structure is a common reason why significant pieces of steel members are removed without fully understanding the loss in strength of the member. This is particularly prevalent in existing older structures that are modernized to include central heating and air and the addition of Ethernet cables. Web damage in steel members exposed to the elements can also occur due to corrosion, where the material is weakened and damaged to the point where it is no longer able to carry the load.

While several papers address the issue of holes being intentionally placed in steel beams, this work does not extend to steel columns where reductions in load carrying capacity could result in catastrophic failure of a structure. Therefore, this work would fill a knowledge gap in the field of structural engineering and better prepare practicing engineers to assess the safety of damaged structures.

The axial compressive strength of web-damaged steel columns will be studied using both a variational analytical approach and computational models. An empirical equation based on the results of the analytical model and a computational parametric study will be proposed as a tool for practicing engineers to determine a quick and reasonable approximation of the capacity of locally web-damaged steel columns. The developed equation will be validated using detailed finite element analysis.
