Before we dive into the nerdy calculations, it’s good to get an overview of the steps that need to be taken to design a steel column – in this case, an axially loaded column. 1. Calculate characteristic loads that act on the column 2. Load combinations 3. Define properties of steel column 4. Cross … See more Steel columns are used in 1. Warehouse structures 2. Temporary event structures (tents, stages, etc.) 3. Buildings 4. Scaffolding 5. Renovation projects as “reinforcement” of … See more Load combinations combine several load cases and multiply the characteristic loads with safety factors. Luckily we have already written an … See more There is a variety of different static systems that the structural engineer can choose from, and often the columns act together with beams … See more The loads of a structure depend on its location, geometry, building type and other factors.
