Which structural framing systems and materials are most commonly used in the United States for residences? For office buildings?
◦ What factors explain why those dominate?
Wood is cheapest for low-rise; steel and concrete offer necessary structural rigidity, lateral wind/seismic resistance, and acoustic dampening for taller structures
◦ Why did you choose your system, and what did it cost you?
I chose concrete. It costed be looks. Visually concrete looks bad.
You sized members by judgment rather than analysis.
◦ What did you base your first guess on?
◦ Why is it safer to guess large and shrink than to guess small and grow?
◦ At what point in a real project does the engineer take over from the guess?
Design teams link and share models rather than working in one file.
◦ What are the advantages of linking?
Multi-Disciplinary Autonomy: Architectural and structural teams work independently in dedicated model files
◦ What errors does linking make possible that a single model would not?
There was so many bugs. Many screens and views kept disappeared I had to keep uploading to cloud and always save to a certain folder. When I had it on my computer it would stay put.
◦ Why is getting shared coordinates right at the start so much cheaper than fixing it later?
If origins or shared coordinates are incorrectly set, linked models will open out of alignment in 3D space
Not every clash is a problem.
◦ On what basis did you classify a clash as an issue versus not an issue?
inor physical overlaps caused by software modeling tolerances (such as the 12-inch check tolerance setting) such as embedded connections
◦ Who should have authority to close a clash on a real project?
The VDC / BIM Manager
Your beam depths just constrained next week's ductwork.
◦ Where in your building is the ceiling plenum now tightest?
◦ What would you give up to get it back?
◦ Should the structural engineer have consulted the mechanical engineer before setting spans?
