Many of these structures, such as one- or two-family residential dwellings, do not require specific fire-resistance ratings rpe building codes but may require unrated membrane protection.

TIPS FOR PREVENTING FLOOR NOISE Trus Joist® TJI® joists are structurally uniform and dimensionally stable, and they resist shrinking and twisting. This helps prevent gaps from forming around the nails between the joist and the floor panels—gaps that can potentially cause squeaks or other floor noise. Using TJI® joists can help you build a quieter floor, but only if the entire floor system is installed properly. This is because other components of the floor system, such as hangers, connectors, and nails can be a source of floor noise. Properly Seat Each Joist Use Adhesive and Special Prevent Shrinkage Avoid “Shiners” in Hanger Nailing When Needed Construction adhesive Movement Gaps develop as sheathing shrinks Shiner Dab subfloor adhesive Bend tab in seat of hanger* and fasten Seat the joist tight to the bottom of the Nail interior partitions to the joists when Keep building materials dry, and properly Exercise care when nailing.

That’s why we developed TJ-Pro Rating. For over 50 years builders have looked to the Trus Joist name for guidance on floor performance, and our decades of proven success with TJ-Pro Rating is one of the biggest reasons why. How TJ-Pro Rating Works: Point values up to 65 are assigned using complex algorithms based on field and laboratory research conducted on over 600 floor system assemblies. It also factors in the variables listed under Key Factors Affecting Performance shown on page 5. Ranges can then be regularly correlated to performance expectations for the builder demographics listed below. Entry-Level Move-Up / Mid-Level High-End Luxury Much of the focus in this Builders in this demographic are Decision-drivers for builders in this demographic revolves around generally driven by Efficiency and demographic generally revolves Economy (cost) and Efficiency Image.

  • Truss Deflection
    Truss Deflection Truss deflection may be something you do not give much thought to when designing trusses. Unfortunately, meeting the code permitted deflection ratio does not always guarantee satisfactory performance. Regardless of what the codes say, most people regard large levels of deflection as a sign of structural deficiency. Paying attention to deflection may be the key to whether your customer is satisfied with you as a supplier and continues to buy your products. Deflection of a truss is generally based on the amount of vertical movement from its original position due to the loads applied to the members. The amount of deflection depends on the span and stiffness of the members, and the magnitude of the loads applied. Codes provide the maximum allowable deflection limits for floor and roof trusses, which is based solely on the truss span. Generally, for roof trusses, the deflection in inches due to live load cannot exceed the span in inches divided by 240 (L/240) and due to total load L/180. For floor trusses, the deflection in inches due to live load cannot exceed the span in inches divided by 360 (L/360) and due to total load L/240. To meet code deflection criteria, a 40-foot span roof truss could have live load deflection 2 inches, which does not ensure satisfactory performance. MiTek engineers recommend using the deflection limits listed below. Page 1 of 5 10 /12 /20 20 Truss Deflection Roof Trusses should use the following settings: In MiTek 20/20 Engineering go to Setup – Job – Design Info – Deflection: In Structure with Truss Design go to File – Setup – Job Properties - Job Settings – Design – Building Code Settings: Please note the settings for cantilever and overhang are half that of the main span.

  • Rolling Roof Trusses,” Pp
    Rolling 94 FINE HOMEBUILDING Roof Trusses Factory-made trusses save time and give you a roof engineered for strength and stability BY LARRY HAUN oof trusses offer many advantages. They are lightweight (generally made from kiln-dried 2x4s), so they Rare fairly easy to handle. Because trusses are engineered, they can span longer distances without having to rest on interior bearing walls, allowing for more flexibility in room size and layout. Finally, installing trusses on most houses is pretty simple. If you want to get a house weatherized quickly, roof trusses are the way to go. Ceiling joists and rafters are installed in one shot, and no tricky cuts or calculations are required. Lay out braces as well as plates Laying out the top plates for trusses is the same as for roof rafters. Whenever possible, I mark truss locations on the top plates before the framed walls are raised, which keeps me from having to do the layout from a ladder or scaffolding. For most roofs, the trusses are spaced 2 ft. on center (o.c.). I simply hook a IT’S EASY TO KEEP A STRAIGHT FASCIA Even if the walls aren’t perfectly straight, the trusses can be. To keep the eaves aligned and the fascias straight, you can take advantage of truss uniformity. Snap a chalk- line along an outside top plate (top photo). Align a mark on the truss with the chalkline when you set the truss (photos right).

What is a truss? A “truss” is formed when structural members are joined together in triangular configurations. The truss is one of the basic types of structural frames formed from structural members. A truss consists of a group of ties and struts designed and connected to form a structure that acts as a large span beam. The members usually form one or more triangles in a single plane and are arranged so the external loads are applied at the joints and therefore theoretically cause only axial tension or axial compression in the members.

    Chambers Covered Railroad Bridge Salvage and Rehabilitation Gregory W. Ausland, PE Greg has more than 27 years of Senior Project Manager civil/structural design and project management experience, OBEC Consulting Engrs and since 1989 has had the Eugene, Oregon, USA distinctive experience of being [email protected] the designer and/or project manager on rehabilitation and repair projects for 32 of Oregon's 50 covered bridges. Tony LaMorticella,PE, SE Inspired by the graceful bridges Sr. Project Engineer on the Oregon Coast, Tony became an engineer after OBEC Consulting Engrs building custom furniture for 15 Eugene, Oregon, USA years. He's been engaged in [email protected] structural design for 20 years, and has been lead design engineer on 18 covered bridge rehabilitation projects. Summary The Chambers Covered Bridge was built in 1925 and is the last remaining covered railroad bridge in Oregon, possibly the only one west of the Mississippi. Therefore, its rehabilitation was critical to historic preservation efforts of the country's remaining covered rail bridges. Before rehabilitation, the 27.4 m (90-foot) long timber structure was in danger of collapse after decades of neglect. In 2010 a windstorm threatened to destroy the bridge. This unique, single-span, four-leaf Howe truss structure was dismantled and rebuilt using almost all the original iron and hardware, and 25 percent of the original timber. The bridge was reconstructed on dry ground and launched onto the existing concrete piers. The rehabilitated Chambers Covered Bridge now serves as a landmark pedestrian and bicycle crossing that provides safe access across the Coast Fork of the Willamette River.
