Picture this: How they actually connect I-beams together. So you're designing a building and the requirement has beam columns connected together. How are they really connected? How will that connection be affected by the larger forces on the structure? If you don't know the reality, you can't create a good model simulation! Love this site. It shows some great pictures that connect the theory with the reality
