The iconic skeletal structure of a steel building is normally concealed when construction is completed. I’ve made an animation of a mock steel building construction sequence to highlight the significance of different building elements. It begins with columns and beams that are further stabilized with joists and decking to form a frame. A non-load bearing curtain wall hangs on these bones. Gypsum sheathing, and a water resistant barrier such as Tyvek seal off the interior. A rainscreen turns back most rain and wind, while allowing airflow behind the assembly so that the wall assembly will dry out after a storm.
Below are some 3d diagrams I developed to illustrate standard steel details. I used two different graphic methods: slide highlights and a single-image section-cut with callouts.
