Maximize Economy and Simplify Frame Construction
Structural steel moment frames are advantageous due to their rapid construction schedule and architectural versatility. A key factor with steel moment frames is selecting a beam-column moment connection that can be designed, fabricated, and erected economically as the moment connections are a key driver during frame fabrication and construction. Using field-welded connections simplifies design but takes more time and resources to erect and inspect. Field-bolted moment connections require more rigorous design but save time and money during fabrication and erection. DuraFuse Frames field-bolted connections make this decision simple by reducing the frame construction cost by lowering tonnage, simplifying fabrication and shortening the erection schedule. Our complimentary design assist includes preliminary design studies to identify the best solution for the project and provide information that can be used to accurately estimate frame construction costs. During the detailing phase we have freely available plug-ins for both Tekla and SDS2 to automate connection detailing. As the project progresses our team will continue to optimize the design finding the most cost-effective solution given the project demands.
DuraFuse connections are designed to be both fabricator- and erector-friendly and do not require special certification. The connections are fully field-bolted, thereby shortening the erection schedule. Erecting a DuraFuse connection does not require installing pieces in the shop that are then removed in the field or “threading the needle” to fit the beams to the columns. For seismic projects several detailing and fabrication requirements are relaxed which reduces cost and schedule beyond the fact that our frames are already lighter. DuraFuse eliminates the seismic lateral beam braces which is typically at least 2/3 of the braces on a project. This eliminates the fabrication, erection and conflicts associated with these pieces further reducing cost and time to construct the frame. The DuraFuse “Protected Zone” is just on the bottom fuse plate. Both the beam and the column are not part of the “Protected Zone” which minimizes RFIs and other issues associated with adjustments, conflicts, repairs, or modifications to the erected frame.
No matter the project location or size, we can assist with designing the most economical solution for your project. At DuraFuse, we strive to be a trusted partner from early design all the way through completion of construction and beyond.
Tip: The Resources section of the website has downloadable plugins for TEKLA, SDS2, and REVIT to make modeling and detailing easy.
Earthquake Resilience and Sustainability
One of the most innovative and valuable aspects to DuraFuse Frames is the repairability. For high seismic regions, building codes address life-safety, but not post-earthquake functionality. Buildings that absorb damage to the structural system will require significant time and resources for post-event repairs which may lead to demolition. With DuraFuse Frames, structural damage is confined to a replaceable fuse plate reducing post-earthquake repair time and cost by at least 60%. Focusing damage in a replaceable component makes buildings both sustainable and resilient as the probability of demolition and re-build is significantly reduced. DuraFuse Frames combines repairability and economy, meaning that you don’t have to settle. The building will have the lowest frame construction cost and can be rapidly reoccupied after a major earthquake.
