AIA-registered provider Growing interest in mass timber has led to increased use not only of cross-laminated timber, but nail-laminated timber (NLT or nail-lam) — a lesser known but ostensibly more common material option. NLT is created by fastening pieces of dimension lumber, stacked on edge, into one structural element with nails or screws. It offers a unique aesthetic, flexibility of form, fast erection and a light carbon footprint — and is a cost-effective option for designers looking to expose wood structure. Using lessons learned from real projects, this workshop will provide practical strategies and guidance for the safe, predictable, and economical use of NLT. Discussion will include architectural and structural considerations, envelope and fabrication details, and key information from the Nail-Laminated Timber Design and Construction Guide , which was authored by the speakers. workshop description 1. Review conceptual, planning and detailing considerations associated with NLT, including MEP, acoustics, and form variation. 2. Discuss engineering procedures for gravity and lateral design, including connection design, special loading conditions, and calculating fire resistance. 3. Study the design of NLT assemblies as building enclosure elements, while evaluating ways to mitigate heat, air and water flow into and out of the building. 4. Consider how NLT is prefabricated and installed, along with best practices for material procurement, tools and equipment, shipping, storage, and lifting. learning objectives gravity 1 design lateral 2 design 3 connections odds & 4 ends overview gravity design 2x “joists” at 1-1/2 inches choose: depth, profile species, grade continuous vs. butt-jointed laminations design approach gravity design NDS: CL, CF, Cr Other: Klayup , Ksection adjustment factors gravity design w L LL wL 2/10 ∆ = 0.0069wL 4/(EI) joint rules per IBC 2304.9.2.5 IBC 2304.9.3.3 NLT Guide Table 4.1 bending strength: 0.67 stiffness: layup factors based on 0.69 IBC Table 2306.1.4 Klayup gravity design w w L L L wL 2/8 wL 2/8 ∆ = wL 4/(185EI) ∆ = 5wL 4/(384EI) joint rules per IBC 2304.9.2.5 IBC 2304.9.3.3 bending strength: NLT Guide Table 4.1 0.202 (L/d) 1/4 / s 1/9 stiffness: layup factors based on 0.0436 (L/d) 9/10 / s 1/5 European research Klayup Klayup • 2x8 NLT • prefabricated with random staggered joints • clear span = 18 feet • 2-span continuous panels • nail spacing: two rows at 10 inches L/d = 18 (12) / 7.25 = 29.8 s = 5” design example Klayup strength: . ./ K, / . stiffness: . ./ K, / . !" reducing nail spacing to two rows at 5 inches revises K factors to 0.43 and 0.77, respectively design example gravity design d2 Ksection d1 X1 = X2 = 0.5 bending strength and stiffness: 3 X1 + X2 (d2/d1) shear strength: X1 Ksection Ksection d1 = 5.5” d d2 = 3.5” 2 d1 X1 = 1/3 X2 = 2/3 bending strength and stiffness: * .

  • Itening Guide
    itening Guide There are three essential tasks involved in the making of any woodwork project. The first is to cut out and shape the components; the second is the joining of those components; and the third and final task is the finishing of the article. This appendix provides you with information about the best ways to fasten your workpieces together, to ensure your project's long life. The options are between adhesives, nails, screws and bolts. NAILS Nailing is a quick, efficient and economical way of joining timber. lf the correct nails are chosen, there is no reason why the joints should not be durable. Timber framed houses, with most of the framing just nailed together, have stood the test of time. The listing of nail types that follows provides an overview of commonly used nails. This listing is not complete - nails exist for specific purposes such as boat-building, but these are outside the requirements of the normal handyman. _ Nail Types: Gommon Bullet Head: Used for hardwood framing and general fixing. Flat Head: Used for softwood framing, fixing softwoods or anywhere bullet heads would tend to pull through. Wire Brads: Small bullet head nails, used for attaching decorative mouldings. Clouts: Small nails with a relatively large flat head, used for attaching thin sheet material. Nail Types: Special Purpose Tacks: Used principally for upholstery; commonly blue- black in colour. Panel Pins: Used for fixing plywood panelling to timber framing; "brown" plated. Hardboard Nails: Used to attach hardboard ("masonite"); generally zinc plated. Plaster Board Used for fixing plasterboard to timber framing; Nails: zinc plated.

  • Wood Connections That Typically Use Nails, Bolts, and Some Specialty Hardware
    CHAPTER 7 Connections 7.1 General The objectives of connection design are • to transfer loads resisted by structural members and systems to other parts of the structure to form a “continuous load path”; • to secure nonstructural components and equipment to the building; and • to fasten members in place during construction to resist temporary loads during installation (i.e., finishes, sheathing, etc.). Adequate connection of the framing members and structural systems covered in Chapters 4, 5, and 6 is a critical design and construction consideration. Regardless of the type of structure or type of material, structures are only as strong as their connections, and structural systems can behave as a unit only with proper interconnection of the components and assemblies; therefore, this chapter is dedicated to connections. A connection transfers loads from one framing member to another (i.e., a stud to a top or bottom plate) or from one assembly to another (i.e., a roof to a wall, a wall to a floor, and a floor to a foundation). Connections generally consist of two or more framing members and a mechanical connection device such as a fastener or specialty connection hardware. Adhesives are also used to supplement mechanical attachment of wall finishes or floor sheathing to wood. This chapter focuses on conventional wood connections that typically use nails, bolts, and some specialty hardware. The procedures for designing connections are based on the National Design Specification for Wood Construction (NDS) (AF&PA, 1997). The chapter also addresses relevant concrete and masonry connections in accordance with the applicable provisions of Building Code Requirements for Structural Concrete (ACI-318) and Building Code Requirements for Masonry Structures (ACI-530)(ACI, 1999a; ACI 1999b).

  • Roof Nailing Over Skip Sheathing
    TECHNICAL NOTE APA Structural-Use Panels Over Spaced-Board Roofs Number P300C January 2006 When replacing roofing, it is often necessary to cover spaced boards with a solid roof deck. APA Rated Sheathing panels, which include plywood and oriented strand board, may be used for this purpose. When the panels are attached over the spaced boards to the rafters or trusses, the resulting roof structure will have greater resistance to wind and seismic forces than the original spaced-board roof. The spaced boards do not have to be removed or replaced, except to repair decayed, broken or warped pieces. The recommendations in this Technical Note are consistent with ASCE 7-02 and the 2003 IBC for wind uplift capacity for design wind speeds up to 100 mph (3-second gust) and a gable-end or hip roof with a 30-foot mean height with a slope between 2/12 and 12/12 at an inland location (Exposure B). Hurricane-prone regions of the Atlantic and Gulf coasts will typically require additional fastening to resist higher wind-load forces. The existing roof sheathing boards are assumed to be 1-inch nominal boards at a maximum spacing of 12 inches o.c. Structural requirements for the panels are usually minimal because of installation over the spaced boards. Panels 5/16 inch or thicker may be used. Panels should be allowed to acclimatize for a few days before installing on the roof. Acclimatize panels by standing them on edge, out of the weather, with space between each for air circulation. APA recommends that all panel end and edge joints be spaced 1/8 inch at time of installation, unless otherwise recom- mended by the panel manufacturer.a Cover sheathing as soon as possible with roofing felt for extra protection against mois- ture prior to roofing application.

  • Selecting the Right Fastener
    selecting the right fastener what’s the difference? In woodworking and construction, a nail holds materials together by friction in the axial direction and shear strength laterally. In general, nails are typically made of steel, and are often dipped or coated to prevent corrosion in harsh conditions or improve adhesion. Ordinary nails for wood are usually of a soft, low-carbon or “mild” steel (about 0.1% carbon, the rest iron and perhaps a trace of silicon or manganese). Nails for concrete are harder, with 0.5-0.75% carbon. A screw is characterized by a helical ridge, known as a thread, wrapped around a cylinder. The most common uses of screws are to hold objects together and to position objects. Some screw threads are designed to mate with an internal thread (often in the form of a nut). Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The screw head allows it to be driven, and is usually larger than the body of the screw. This keeps the screw from being driven deeper than the length of the screw and provides a bearing surface. The majority of screws are tightened by clockwise rotation. nail or screw? Many nails and screws in the market are designed to perform the same function, so when determining which to use, consider the following: 1. If your application has sideways pressure where material would have the tendency to move left or right, use a nail – for example, when you have a frame, you will get a lot more side-to-side pressure.
