© John R Haymaker 2010 Designers process: Decision Matrices Structural options and a decision matrix Score Key: 3 = Much Better, 0 = No Effect, -3 = Much Worse, ? = not enough info to decide Comments Score Comments Score Str uct ure + Garage will be less expensive + Superstructure less cost but Turner should confirm ? - Probably not enough regularity to make concrete inexpensive? ? No n- Str uct ? ? Mi ni + Faster to erect 2 - Not enough regularity for fast erection -1 Co lu mn = 12" Deep. If Finishes & Fireproofing is required, 18" total. 0 = 18-24" Exposed, larger under large transfer girders 0 + No wall in E-W direction because of MFs Ab ov e + More efficient transfer (e.g. vierendeel truss?) 2 - 48" Deep Transfer Girders -2 Ar ou nd Op - Slightly Deeper Around Perimeter + More flexibility ? + Thinner Profiles - less flexibility, beams fly through large openings ? At Ext eri - Thicker Exterior Perimeter (18") -1 + Thinner Profiles (8") 1 Roof Framing + Steel allows much flexibility. All steel roof is probably cheapest. 2 - Probably will need steel or timber, so new contractor needs to be brought in -1 + Geometry not limited. Cost of geometric irregularities is less relative to concrete. 1 - Openings, cantilevers, notches harder to accommodate without increasing depth. -1 Future Flexibility + Easier to add floor openings later + Easier to poke holes through beams + MF provides more space flexibility in E-W direction + BF allows openings for future 2 - More difficult to accommodate future services, because there are beams and big concrete walls -1 + relatively light 2 - 30% Heavier FOB -3 + easier to poke through steel beams and around braces - but more beams in the way horizontally.
