John Kissinger, P.E., S.E., who worked on the project almost from its inception, will give insight into someof the project challenges. The project was named the Number One Design of 2001 by TIME magazine, and has wonState, National and International engineering awards.Mr. Kissinger was Project Manager overseeing structural, civil and environmental engineering for the development,for the firm of Graef, Anhalt, Schloemer and Associates. In addition, Mr. Kissinger also managed his firm’s work asAssociate Landscape Architect to the office of Daniel Urban Kiley.Mr. Kissinger will discuss how this unique project came to be, particularly with regard to the structural design. He willgive an insider’s perspective to unusual structural features of the building, including its kinetic roof structure, the“Brise Soleil”. He will also discuss the dynamics of its international design team, and the effect that this landmarkstructure has had on the community.ABOUT THE SPEAKERJohn Kissinger is a Vice President with Graef, Anhalt, Schloemer & Associates, Inc., an ENR Top 500 firmheadquartered in Milwaukee, Wisconsin. John’s broad range of experience encompasses engineering, marketingand management. He has developed a keen understanding of the special needs of clients, and has been an activeparticipant in distinctive projects that have become symbols throughout the Midwest.As an engineering manager, John has worked on projects with construction costs ranging from a few thousanddollars to several hundred million. His recent large-scale project management experience includes the internationallyacclaimed Milwaukee Art Museum Quadracci Pavilion, designed by Santiago Calatrava and winner of TimeMagazine’s No. 1 Design of 2001, and the Midwest Airlines Center, a 700,000 square foot convention center locatedin downtown Milwaukee. Additionally, he has been the firm’s principal-in-charge of both civil and structuralengineering teams for the $290 million expansion of the Green Bay Packers’ Lambeau Field stadium, as well ashead of a team assisting in the structural design of the $850 million expansion of McCormick Place ConventionCenter in Chicago, and a team providing civil engineering and site development services for the new 49-acre CampJohn Paul Jones at Great Lakes Naval Base.John is a registered Professional Engineer in Wisconsin, Ohio, Michigan and Nebraska, a Licensed StructuralEngineer in Illinois, and a LEED Accredited Professional. He is also a member of the American Society of CivilEngineers and the American Concrete Institute, where he is Past-President of the Wisconsin Chapter. John washonored as one of the “Top 25 Newsmakers of 2001” by Engineering News-Record Magazine.He and his wife Debbie have three children and live in Wauwatosa, Wisconsin, a suburb of Milwaukee.

Thesehelpful tips should help you keep bolts fromdriving you nuts, and welds from torchingyour temper.Connections can be expensive, and they cantake a lot of effort to create during the designand construction process. How can you savetime and money – and make everybody’s workeasier when working with connections on fasttrackschedules? Here are some generalguidelines for structural engineers for the designof economical bolted and welded connectionsfor columns, beams and braces. (Editor’s Note:Part I (Items 1-26) were published in January’snewsletter; Part 3 (Items 41-57) will follow inMarch.)27. Wherever possible, specify bearing joints.It makes the most economical use of bolts,eliminates masking or a special paintsystem, and reduces installation andinspection requirements.28. Use snug-tightened joints as much aspossible.29. Favor ¾” diameter A325 bolts for typicalstructures.30. Try to limit bolt diameters to 1” or smaller.Larger diameters require specialequipment, larger spacing and edgedistance, and special 5 / 16”-thick washers(ASTM F436) for fully pretensioned ASTMA490 bolts.31. Never use bolts with the same diameterbut different strengths on a job – it canlead to mistakes.32. Use short-slotted holes in outstanding legsof connection angles, end plates andsingle-plate connections.33. When loads are large, consider largerdiameter bolts and/or ASTM A490 bolts.‣ Bolt material cost is roughlyproportional to strength.‣ Higher strength bolts save inconnection material, hole-making,and installation cost.34. Consider excluding bolt threads (X-bolts)for:‣ Heavily loaded connections wheretypical bolt size doesn’t give enoughcapacity.‣ Shop assembled trusses.‣ Connections when outer plies are 3 / 8”thick or larger.35. Use slip-critical connections for:‣ Bracing connections with oversized orslotted holes.‣ Field-assembled trusses with oversizedholes.‣ Members with short / long-slottedholes when force applies parallel tothe slots.‣ Built-up compression members.‣ Cyclic loads.36. Where fully pretensioned bolts areneeded, permit the use of any of thefour methods approved by RCSC andAISC:‣ Turn-of-nut.‣ Calibrated wrench.‣ Twist-off-type tension-control bolt.‣ Direct-tension-indicator.37. Mechanically galvanized ASTM A325bolts provide excellent corrosionresistance and require a minimumovertapping of nuts and easierpretensioning.38. Keep your bolt holes as rational aspossible‣ Don’t use different hole sizes in thesame member. It leads to mistakesand slows fabrication becauseshop re-tooling is required for thepiece.‣ Don’t specify slots in materialthicker than bolt diameter plus 1 / 8”.The AISC Specification doesn’tallow punching holes in suchmaterial, and it is difficult to makeslots. A good alternative would beto use oversized holes.‣ Use the same oversized holes in allplies if it is possible.‣ Use long-slotted holes in girts andany members that must be fieldalignedto tolerances other thanstandard steel framing tolerance(for example, curtain wallconnections).39. Correctly apply AISC requirements forfillers:‣ Fillers in slip-critical joints are notrequired to be developed.‣ Fillers up to ¼” thick can be used inbearing joints without reduction instrength.‣ Fillers up to ¾” thick don’t have tobe developed if the design shearstrength of the bolts is multiplied bythe factor [1 – 0.4(t – 0.25)], wheret is the total thickness of the fillersup to ¾”.‣ Fillers over ¾” must be developedby bolts or welds, in or outside ofthe joint.40. Leave extra holes open. In almost allcases they don’t need to be filled, andfilling takes a lot of time (think laborcosts), especially for thick members.About the Author: Victor Shneur, P.E., is achief engineer with LeJeune Steel Companyin Minneapolis, MN.
