Major Reduction in Shop Labor
How Does SIDEPLATE FRAME® Improve the Answers to these
Typical Questions?More Economical AND Greener?
– Reduced Detailing?– Reduced Tonnage?– Reduced Shop Man Hours?– Reduced Field Welding?
Shorter Construction Schedule?
Mega Performance?
How do Specify?
License Fee – How much & Who Pays?
GSA Federal Courthouse
Reduced Reduced Detailing costs? Yes!Detailing costs? Yes!SIDEPLATE FRAME® Experiences a significant
reduction in detailing costs compared to past projects because:
Shop installed beam stub has been eliminated and replaced with a Field installed full-length beam resulting in: Elimination of link beam and beam stub
coordination throughout shop drawings
Standardization of all connection designs and dimensions
Elimination of side plate extension below bottom of beam = no more MEP coordination around joints.
Tekla and SDS2 tools for ease of moment frame joint detailing.
Reduced Reduced Detailing costs? Yes!Detailing costs? Yes!SIDEPLATE FRAME® example in Tekla :
Detailers note: Top Of Steel (TOS), is set by the bottom edge of SidePlate {A}.
Reduced Tonnage? YES!Reduced Tonnage? YES! SIDEPLATE FRAME® Continues to Save 20-30% in Lateral Steel Tonnage over ALL other Moment
Connection Systems
How? Because of SidePlate connection stiffness 100% panel zone and 3*Ix beam ends
20-40% lighter beams and up to 60% lighter
columns results in: 1- 4 lb/sf net tonnage savings or 10-
20% overall project weight reduction, including connection plate weight (depending on seismicity level & progressive collapse requirements)
FYI: For maximum savings, use of W18-W24 Columns in Lower Seismic Regions and W24-W30 Columns in Higher Seismic Regions are typically the most economical column sections to utilize for any moment frame designs
Reduced Shop Man Hours? Yes! Reduced Shop Man Hours? Yes! SIDEPLATE FRAME® Experiences a 50% reduction in
shop labor compared to past projects because:
Shop installed beam stub has been eliminated and replaced with a Field installed full-length beam resulting in: Significant reduction in shop handling and
welding time Elimination of beam end preparation for field CJP
welding No Wide Trucking Loads
New Non-Linear F.E.M. based connection designs have up to 50% smaller fillet welds than before and lighter connection plates resulting in: 50% reduction in shop welding 1/4” – 5/8” typical shop fillet welds 8-12 shop man hrs/ton for the lateral system
Reduced Field Welding? YES!Reduced Field Welding? YES! SIDEPLATE FRAME® Continues to Save 50-60% in
Field Welding Time over ALL other Moment Connection Systems with an Erected Full-Length
Beam
No Ultrasonic Testing of Beam-to-Column Connections
No removal of bottom girder flange backing bar saves:
About 1 hour per beam end for- Back gouging &
- Reinforcing fillet welds
All decking can be installed prior to field welding (no safety issues)
Lighter & deeper columns have thinner flanges & webs, which reduce column splice CJP welding hours by 50-65%
100% Fillet Welding is Faster & Easier (No Beam CJP Welds)
Shorter Construction Schedule? Shorter Construction Schedule? YES!YES!
SIDEPLATE FRAME® Continues to Reduce ScheduleFewer Moment connections
mean: Shorten Construction Schedule Open for business sooner and Save on interest paid on construction loans
No CJP welding: Special Inspection Costs are reduced by a
minimum of 50% on non-essential facilities.
No UT inspections in the shop or the field Magnetic Particle Testing of 4 fillet weld
ends is faster and more certain than Ultrasonic Testing of beam-to-column CJP welded tee joints
Column procurement is predictable & domestic Eliminates long & uncertain overseas

Shop Drawing with proprietary notice Once you have one or two of these drawings put together send them
over for a quick SidePlate review. Then they should be submitted through the normal procedure. Typically SidePlate will review the SidePlate moment connections at the same time as the EOR is reviewing the rest of the shop drawings

Begin with Column Sub-Assembly
Step 1: Column Tree Assembly
Bring in Side Plates, Tack Weld into PositionBring in Horizontal Shear Plates, Tack, Check Alignment, Apply Welds 1 and 3Rotate Column into Position to Apply Other PlatesBring in Side Plates and Horiz. Shear Plates, Tack into PlaceApply Welds 1 and 3, Bring in Temporary DogsApply Weld 2, NS/FS. Rotate Column to Apply Weld 2 to Other Side Plates (Not Shown Here). After that, Column Sub-Assembly Complete.
Placement of Side Plate {A} – step 1, verify alignment and placement and
double check holes
Placement of Side Plate {A} – step 2, place welds {1} & {3} without dogs – allowing side plates {A} to freely
move
Placement of Side Plate {A} – step 3, place dogs on the inside of side plates
before welding to column flange (do not tack at this time), slight spreading may be desired at this point, to compensate
for weld {2} shrinkage
Placement of Side Plate {A} – step 4, place weld {2},
Note: tacks shall be incorporated
into the final welds
Placement of Side Plate {A} – step 5, after weld {2} has cooled, remove bottom support (dog) and measure
Measure Dimension ‘Z’ opening here (most critical is about 2” from face of column).
Placement of Side Plate {A} – step 6. If the desired spread (Dim ‘Z’) is satisfied at the
bottom edge of side plate {A}, tack top dog for shipment to the field
Bottom edge of side plates, measure opening here
Note: top edge of side plates will likely be spread more than the bottom edge, as shown: bottom is 12 ¼” and top is 12 ½”
Top edge of side plates, place dog here
Placement of Side Plate {A} – step 7, if needed
If further spreading is required, Maximum separation shall not exceed width of column flange + thickness of side plate {A}, unless otherwise approved

Step 4: Remove Top Dog… (which provides ¼” rattle space for ease of erecting bm)
Top Dog removed and tightened bolts -help eliminate root gap
Metal Deck is Placed (no safety issues)
Step 5: Place 4 Horizontal Fillet Welds (cover plates to side plates)
Step 6: Field Items - Gap Closurebent plate or duct tape

Field Items: Fireproofing

So What’s the Bottom line to How SIDEPLATE® Moment Frames
Compare?Overall Net Savings, including License Fees:
Moment Frame to SidePlate - ranging between 5-15% in Total Steel Fabrication &
Erection Costs or $1-$4/sf Construction Costs PLUS Weeks of Critical Construction
Schedule
Multi-story Braced Frame to SidePlate - Designs typically resulting in either a “wash” or
even an overall net savings of as much as $2/sf in Construction Costs PLUS a Shorter
Construction Schedule
Fabricator & Erector Fabricator & Erector TestimonialsTestimonials“I really like your new SidePlate FRAME® system. It has gone up faster than we had anticipated and we’ve
had to send our crane operator home a few times because we ran out of steel. Erecting and welding the SidePlate FRAME® system is easy and we are very pleased with it. It’s a very nice system. It’s better than other moment connections because it puts a lot less heat and stress on the columns. We are looking forward to the next one!”
Steve Eckes, General ForemanDiversified Metal Works, Orange, CA
“SidePlate is already recognized as being the nation’s best choice for blast resistant structures. Hirschfeld’s experience with the innovations incorporated into the new SidePlate FRAME® system tells us that it could soon become the standard for all steel frame buildings.”
Dennis Hirschfeld, P.E., CEOHirschfeld Industries, San Angelo, TX
“By using the new SidePlate FRAME® detail, we were able to reduce the weight of the structure and the amount of moment frames required for the project, resulting in a substantial savings to the overall project budget.”
Marsh Spencer, Executive Vice President Steel Fab, Charlotte, NC
“Using your new SidePlate FRAME® detail, we can save $400,000 over your current SidePlate detailing on this project.”
Bob Hazelton, Vice President Herrick, Stockton, CA
“Banker Steel certainly sees big advantages in the new system with the significant decrease in both shop and field welds. Having the beam as one piece will also expedite the work through the shop. We are ready to use this system on an East Coast structure.”
