Drag strap framing. If that's not possible, drag struts need to be provided somewhere within the span of the diaphragm for there to be a complete load path that doesn't Can anyone explain what a drag connection is or better yet, provide a connection example? There is no typical detail nor a section cut showing how to take this off. Drag Struts: Functions, Applications, and Best Practices | ArchitectureCourses. You might have a case where a wall is anchored to a perpendicular drag truss so the drag truss can support the wall in the out of plane direction. 1 Software Version and Standard This tutorial was completed using WoodWorks® US 2019, and NDS 2018. Drag struts play a crucial role in distributing lateral loads in buildings. org Strap reinforcement of a collector or drag line beyond the end of a shear wall; solid sawn joists perpendicular to the wall. The DSC2 is a For a collector to work, it must meet the following conditions: 1. We also stock a full selection of Strong-Tie post bases, joist hangers, holdowns & more. The key to this connection is that it uses self-drilling screws to create a superior connection to that achieved with Framing a drag truss over an interior shear wall can help alleviate stress concentrations at diaphragm openings, re-entrant corners, offsets, or reduce the aspect ratio of the diaphragm. Collectors in Drag loads are due to lateral (horizontal) loads generated in high-wind or seismic events. A34 Framing Clips; A35 Framing Clips; LTP Lateral Plate Ties; L-Series Angle Clips. Mar 2, 2019 #6 jayrod12 Structural. com/framing/index. We have had a lot of questions about how to actually make and install the stra Framing Clips. html Visit our website today to learn more about structural engineering, home building The Simpson Strong-Tie DSC5R-SDS3 Right Drag-Strut Connector transfers the diaphragm shear forces from the girder truss or beam to the shearwalls. That’s why we’ve partnered with Suppression Gear to offer the VIKCTIM Drag Strap, a My preference is #2. Building Systems Explore more wood design and construction In this short video, Mitchell walks us thru how to instal a simple drag strap. I have a block house and have straps tying the roof to the block. Skip to content Learn. Seismic forces cycle ba Properly designed drag strut trusses, shear walls and roof diaphragms and their connections will transfer lateral loads to the foundation and then safely into the ground. but I suppose with a lateral system in At Toxic Suppression, we believe that no one should ever be stuck in a dangerous situation due to a lack of emergency equipment. Thanks. It must have tensile capacity. The flanges are cut out at the OWSJ and it is welded to the OWSJ top chords. homebuildingandrepairs. A-Series 90° Angles Clips; L Series Angle Clips; LS Skewable Angles; ML 12 Ga. I have seen a channel section used commonly for this purpose. Forces must actually get to the collector. Note that in both of the cases . com/engineering/index. You should be able to answer your question with a properly Such a beam or truss is referred to as a load “collector” or “drag strut”. The American Wood Council’s Special Design Provisions for Wind and Seismic (SDPWS) document provides information and requirements for the design of wood-frame shear walls. Main Menu. Figure 2 (LGSEA Details Manual, 1996) shows two possible framing mecha-nisms of load transfer. html Click on this link to learn more about wall framing, engineering and home repairs. 3. 4. Whether you're an engineer, contractor, architect, or even a homeowner looking to understand structural framing, this guide will break down everything you need to know about drag struts in The DSC drag-strut connector transfers diaphragm shear forces from a girder truss or beam to shearwalls. The DSC5 has been designed to optimize fastener location. These loads are generated within the structure and transferred into load carrying elements (like drag strut trusses, shear walls or My question relates to the one drag strut. Using MiTek In accordance with ASCE 7, a Drag Strut is a structural element (could be a truss) installed parallel to an applied load that collects and transfers diaphragm shear forces to the Connections Tutorial 4 – Design Collectors or Drag Strut ( US) 4. Medium L-Angles; HL Series Heavy Angles; Roof By checking this box, I agree to receive communications from Simpson Strong-Tie in accordance with their privacy policy. Upvote 0 Downvote. Any help would be Different framing techniques may be used to transfer the shear, V, from the diaphragm to the wall. Please let me know your thoughts. The collector must be continuous (or be composed of elements joined together to act as one continuous member). 2. Code Compliance & Inspection Fees. Of the three shear wall design methodologies given in Create a moment frame of sorts with straps, timber lvl beam and posts. It is quickly installed using 3" Hurricane straps are metal straps used to tie the whole thing together. My daughter has a wood frame and her wood sides are 500+ Straps; 2 Steel Moment Frames; 2 Bent Steel Rafters; In the photo to the right, we have an MST60 dadoed into the 6×12 header, an MST60 beam-to-beam drag strap, an MST48 post-to-6×12 header uplift Drag Strut Design: $3,000 – $10,000 (more complex force calculations) 2. Building codes dictate how drag struts and collectors must be installed, and compliance is non-negotiable. Learn their function, design considerations, and best practices in structural engineering.
