• Hall of fames

cylindrical shape is based on the water towers
that nourished steam engines and grain silos
dotting rural landscapes. Four concentric circles
represent the 78-, 45-, 33- RMP records and the
compact disc creates the stair stepping roof.

• The interior
• design was
• inspired by
• country stores,
• and I believe a
• lot more can be
• done to achieve
• this.

• This is what I personally think of when the term
  country general store is mentioned.

Senior Project
Spring 2004
13
Country Music Hall of Fame Museum

• So How Can We Make This Look More Like A Country
  General Store?
• The most observant choice is the surround-ness of
  natural wood for its simple, rustic charm that
  provides a warm, down-home atmosphere and believe
  would recapture Americas earlier days. This
  will be our prime directive.
• And we have two constructible methods
• Enfolding all of the steel beams columns with
  wood.
• Or replace the steel structure with a wooden
  structure.

Senior Project
Spring 2004
14
Country Music Hall of Fame Museum

• Alternative 1 Enfolding the steel with wood
• This is not really desired because it presents a
  false sense of an honest structure.
• Alternative 2 Change the steel to wood
• This illustrates the true veracity of the
  structure and is the preferential.

Senior Project

• This is not really desired because it presents a
  false sense of an honest structure.
• Alternative 2 Change the steel to wood
• This illustrates the true veracity of the
  structure and is the preferential.
• So the motivation is to have an honest structure.

Senior Project
Spring 2004
16
Country Music Hall of Fame Museum

• So You Might Be Asking What Is An
• Honest Structure?
• Well an honest structure is
• A structure that supports itself by its true
  identity.
• Case in point
• An honest structure Eiffel Tower (Supported by
  what you see).
• A non-honest structure St. Louis Arch (The arch
  has no structural capabilities, its a
  post-tensioning concrete structure).

Senior Project
Spring 2004
17
Country Music Hall of Fame Museum

• So How Much Steel To Replace With Wood?
• All of it?
• Could build the entire museum out of wood. This
  would be a true honest structure but would be
  expensive and have to consider cost. Besides
  were only looking for what you can see.
• Or Partial?
• Could only replace what is seen by visitors, this
  would be more cost minded and believed to be
  acceptable as an honest structure.

Senior Project

• And This Is The Choice Were Going With
• All of it?
• Could build the entire museum out of wood. This
  would be a true honest structure but would be
  expensive and have to consider cost. Besides
  were only looking for aesthesis.
• Partial
• Could only replace what is seen by visitors, this
  would be more cost minded and believed to be
  acceptable as an honest structure.
• By the way, least cost is not an issue.

• What Part Of The Museums
• Structure is Seen?
• First floor are staff mechanical areas.
• Second third floors are visitor areas.
• Fourth floor are office spaces.
• The structure is open from the second floor to
  the roof.

Senior Project
Spring 2004
20
Country Music Hall of Fame Museum

• What Are We Replacing?
• Second floor frame will be left in its present
  condition and act as a fire barrier between the
  first and upper floors because of high
  combustible areas (i.e. the commercial kitchen on
  the first floor).
• Second floor will be accorded interior wood
  columns.
• Third fourth floor will be accorded a wood
  floor frame and interior columns.
• The mono-sloped roof will be accorded heavy
  timber trusses.
• The exterior frame will be left in its present
  condition for very important reasons.

Senior Project
Spring 2004
21
Country Music Hall of Fame Museum

• Those Reasons are? Lateral
• Least important, the exterior frame is the
  lateral system for the building, which isnt
  necessary a problem with a wood frame.
• But more important, since we are building a 3
  story wood frame on top of a 1 story steel frame,
  there needs to be connections for story shear
  transfer. This would require a very large
  connection to join the two materials. Thats why
  continuous columns are used with splices, which
  is what we have.

Senior Project
Spring 2004
22
Country Music Hall of Fame Museum

• So Here Is What We Are Doing
• Were going to replace the upper core of the
  building with wood, leaving the entire exterior
  frame and first bay in its present condition for
  lateral stability and fire separation,
  respectively, and shelter the building with a
  heavy timber truss roof.

Senior Project

Country Music Hall of Fame Museum

• Before We Think About Designing With Wood We Need
  To Confirm With
• A Building Code First.
• Museum was designed under SBC 1994.
• And will be redesigned under IBC 2000.

Senior Project
Spring 2004
24
Country Music Hall of Fame Museum

• IBC 2000 Classified this as A-III (Assembly
  Museum), Type-IV (Heavy Timber) Construction
  (This is the worst case)
• Museum has
• 4-Stories (a height of 76)
• 47,700 SQ. FT.
• These figures exceed IBC 2000 Limitations For
  A-III, Type-IV Construction and is repudiated.

Senior Project
Spring 2004
25
Country Music Hall of Fame Museum

• But
• Museum also has
• Sprinklers
• 20 Perimeter Frontage
• These bonuses give an Extra Floor and the
  Additional SQ. FT needed.
• Which is now approved by IBC 2000 for A-III,
  Type-IV Construction and we have the green light.

• What Type Of Wood To Use For Redesign?
• Solid Sawn Lumber Cheap but can only get them
  as big as you can find them out of tree with the
  fewest defects and straightness.
• Structural Composite Lumber (SCL)
• LVL Has greatest stress ratings but consist of
  small strands and is ugly.
• LSL Even smaller strands and even uglier.
• PSL Same as LSL.
• OSL - Same as LSL.
• Box Beams I-Beams Not the desire wanted.
• Glulam Has stress rating slightly lower than
  LVL but is aesthetically pleasing and can be
  obtained as big as you need them with limited
  control defects.

• What Specifications of Glulam?
• Southern Pine because of geographic location
  (Nashville).
• Architectural appearance.
• Contract this out to Rigidply Rafters Inc,
  Lancaster, PA, because of locality for
  visitations.
• Combinations 24F-V3 24F-V5 (V5 for stress
  reversals).

Senior Project

• What is a 24F-V3 ?
• This is the designation for beams
• F Fiber Strength
• 24 2,400 psi
• V Visual Graded
• 3 - of Layups
• Why are we using visual on critical load stressed
  members?
• Were using visual graded because the
  manufacturer is standing behind their work and
  guarantee quality and this is an insult if you
  question them about it.

• About the Structure
• There are no typical bays.
• Although the redesign is straightforward, simple
  beam designs EXCEPT for 3 Locales
• 3rd Floor Corbelled Walkway Cantilevers
• 3rd Floor Simple Span Girders with a 350 psf
  short term load
• 4th Floor Simple Span Girders with 22 Overhangs

• 3rd Floor Cantilever
• Six cantilevers, 21 in length, spaced at 30
  with 100 psf live load.
• Cant design as is with wood because of the
  required moment connection. This would require a
  hellacious wood connection.
• What are our alternatives to a cantilever?
• Could prop the free end of the cantilever with
• A column at the bottom
• A tensed rod from the roof

Senior Project
Spring 2004
37
Country Music Hall of Fame Museum

• But the cantilever is there for a purpose, it
  provides drama.
• So we would like to keep the integrity of the
  cantilever.
• What are other alternatives?
• How about a knee brace to remove the moment
  connection at the column?
• What about clearance?

Senior Project
Spring 2004
38
Country Music Hall of Fame Museum

• Well then, how about a curved knee brace?
• We can curve a Southern Pine glulam to a minimum
  radius of 18.
• Floor to Floor height is 18 so clearance seems
  okay.
• Will the knee brace be below the cantilever or to
  the side?
• We will have two knee braces, one on both sides
  to help reduce the knee brace size and also for
  symmetry, with the cantilever slotted in between.

Senior Project

Country Music Hall of Fame Museum

• What about thickness?
• The steel column is W40x199 with a flange width
  (bf) of 15.8
• What do we have in terms of thickness?
• We have a 3-ply truss a Top Chord sandwiched
  between 2 Curved Knee Braces
• Top Chord will be design with a width of 5-1/2.
• Curved Knee Braces will be design with a width of
  5.

• 3rd Floor Girder w/ Extensive Short Term Load
• Space requires a 350 psf short term load for the
  library.
• 6 simple span girders, 50 in length with a
  5-1/2 Overhang, spaced at 30.
• Left support varies among the six girders.
• Alternatives
• Keep the 30 spacing
• Or reduce the spacing to 15 and try to conserve
  size

Senior Project
Spring 2004
42
Country Music Hall of Fame Museum

• If spacing is maintain at 30, size required is
  14-3/4x52-1/4.
• If spacing is reduce to 15, size required is
  12-3/4x44.
• But in addition to the 15 spacing, we would also
  need
• Additional columns or a transfer girder which
  adds even more material
• So spacing will be kept at 30 and we will use a
  14-3/4x52-1/4.

• If The Largest SP Width In The NDS Is
  10-1/2, How Can We Specify A 14-3/4 Width?
• NDS sizes restrains a naïve engineer from
  irregular or outsized sizes.
• The size of glulam both depth and width are
  actually governed by the machinery, particularly
  the planar, so sizes can be larger than NDS
  sizes.
• Rigidply Rafters can produce widths up to 14-3/4
  thick and 76 deep.
• So you can design larger sizes than NDS sizes.
• The size limits are within the manufacturer, not
  the NDS.

Senior Project
Spring 2004
45
Country Music Hall of Fame Museum

• While on the Subject
• There are numerous combinations (ex 24F-V3) for
  glulam in the NDS specs.
• Out of all the combinations only a selected few
  are actually manufactured, some dont even exist,
  theyre ideal.
• Rigidply Rafters manufactures only two
  combinations 24F-V3 24F-V5
• So you need to call the manufacturer to find out
  what combinations and sizes are available.

Senior Project
Spring 2004
46
Country Music Hall of Fame Museum

• 4th Floor Girders w/ Extensive Overhang
• Space requires a 50 psf short term load, no
  concern.
• Simple span girder though has a 22-6 overhang
  and are spaced at 30.
• Left support varies among the six girders.
• Alternatives
• Keep the 30 spacing.
• Reduce the spacing to 15 to try to conserve
  size, which we know doesnt work
• Knee Braces like 3rd Floor Cantilever.
• Use Fiberglass Reinforcement in the Glulam.
• Support the overhang with a tension rod.
• Flitch Girder.

Senior Project
Spring 2004

Country Music Hall of Fame Museum

• If spacing is maintain at 30, size required is
  14-3/4x59-1/8.
• If spacing is reduce to 15, size required is
  12-3/4x44.
• But in addition, would need also need a transfer
  girder or additional columns for the 15 spacing.
• Knee braces wont work due to obstructions below.
• Fiberglass reinforcement will not work because of
  its low stiffness increase (10).
• Supporting the free end wont erase the load but
  instead transfer it to the roof increasing the
  truss sizes, which we dont want.
• Flitch girder will not keep the integrity of the
  honest structure.
• So the decision is keep the spacing at 30 and
  use a 14-3/4x59-1/8.

• 4th Floor Girder

• Roof Frame
• The museum has 2-1/2 12 mono-sloped roof.
• Framed with 48 open web joists.
• We will redesign with heavy timber truss and
  double sided gusset plates.
• The wood trusses will be spaced 30 and up to
  160 long.
• Glulams will be needed again for strength and
  length capabilities.

• Design
• A Warren web pattern was chosen.
• All of the webs are positioned to carry
  compression allowing the members to resist
  compression and not bolt shear.
• Member widths are 8-1/2 10-1/2
• Member depths are 23-3/8
• The top and bottom chords are continuous and
  spliced ever 2-3 bays for shipment.

• What About Shipment?
• The top two truss are 160 long and 26 tall.
• The bottom seven are 109 long 22 tall.
• How do I ship such large trusses?
• Options
• Could assemble everything on site but would be
  very time consuming and expensive
• Could assemble enough to allow transport and
  assemble the partial pieces on site

• Columns

• The combination will be SP V49 N1M16 4 LAMS
• The largest size required is 12-3/4 x 12-3/4.
• This size can be assembled using a 2x8 and 2x6
  edged butted.
• One prominent disparity between glued-laminated
  columns and beams is the edge gluing required
  for the columns.
• Edge gluing the columns controls lateral
  buckling.

Senior Project

• Connections
• For efficiency we want to connect everything with
  bearing connections, letting the woods grain
  compression do the work and not the bolt shear.
• So were going to use
• Beam Saddles
• Beam Face Hanger Connections
• U-Brackets
• Beam Connections to Continuous Columns
• Timber Rings Shear Ring
• Double Gusset Plates

• Ice-Thermal Storage System
• Saw this in a building in Chicago on the ARCH 443
  trip.
• Ice storage generates ice at night during
  off-peak utility hours and stores it to cool a
  building the next day during on-peak demand time.
• The size of the chillers and cooling towers
  required for an ice system is significantly
  reduced compared to conventional chillers and
  cooling towers.
• Pump and pipe sizes are also reduced in an ice
  storage system as well as condenser water pipe
  sizes and head pressure falls.
• The only physical constraint for ice storage is
  physical space in the building.

• The cost reduction of the steel structure was
  compiled using RS Means 2004.
• Total steel deduction is roughly 350,000.
• This does not include fasteners, SFP, or any
  miscellaneous.
• A full member inventory can be found in the
  appendix of the report.
