Investigation of the Suitability of Finger Jointed Structural Timber for Use in Nail Plated Roof Trusses
University of Southern Queensland Faculty of Engineering and Surveying Investigation of the Suitability of Finger Jointed Structural Timber for Use in Nail Plated Roof Trusses A dissertation submitted by Anthony Glen Dakin In fulfilment of the requirements of Courses ENG4111 and ENG4112 Research Project Towards the degree of Bachelor of Engineering (Civil Engineering) Submitted: October, 2011 Abstract The most common method of roof framing employed by Australian builders in modern construction is the use of pre-fabricated nail plated timber roof trusses. These trusses are predominantly manufactured from structural framing timber limited in length to a maximum of 6 metres. The style and size of houses increasingly preferred by Australian homeowners means that trusses are regularly required to span further than 6 metres. Truss manufacturers therefore use larger or additional nail plates to splice members during fabrication, and the assembly process becomes far more complex. Finger jointing of sawmill off-cuts and other short lengths of timber is a means of manufacturers economically producing timber in longer lengths. This dissertation investigates the suitability of using finger jointed structural timber for the fabrication of nail plated roof trusses. Physical testing and statistical analysis has been used to compare the performance of finger jointed structural timber with standard structural framing timber normally used in truss fabrication. This study involved characterizing the mechanical properties of the timber, as well as assessing the performance of joints including mechanical fasteners. These methods, along with the static modelling of loading situations, were also used to quantify the probability of inducing failures unique to finger jointed timber, during the truss fabrication and erection process. -

TECO Design and Application Guide Is Divided Into Four Sections
Structural Design and Plywood Application Guide INTRODUCTION Plywood as we know it has been produced since early in the 20th century. It has been in widespread use as sheathing in residential and commercial construction for well over 50 years and has developed a reputation as a premium panel product for both commodity and specialty applications. Structural plywood products give architects, engineers, designers, and builders a broad array of choices for use as subfloors, combination floors (i.e. subfloor and underlayment), wall and roof sheathing. Besides the very important function of supporting, resisting and transferring loads to the main force resisting elements of the building, plywood panels provide an excellent base for many types of finished flooring and provide a flat, solid base upon which the exterior wall cladding and roofing can be applied. This TECO Design and Application Guide is divided into four sections. Section 1 identifies some of the basics in selecting, handling, and storing plywood. Section 2 provides specific details regarding the application of plywood in single or multilayer floor systems, while Section 3 provides similar information for plywood used as wall and roof sheathing. Section 4 provides information on various performance issues concerning plywood. The information provided in this guide is based on standard industry practice. Users of structural-use panels should always consult the local building code and information provided by the panel manufacturer for more specific requirements and recommendations. -

Plywood Or Osb?
Form No. TT-047A Page 1 of 5 May 2005 PLYWOOD OR OSB? USED AS INTENDED, THE TWO PRODUCTS ARE INTERCHANGEABLE Since its introduction 25 years ago, oriented strand board (OSB) has played an increasingly important role as a structural panel for all kinds of construction applications. OSB production in the United States and Canada totaled 25.4 billion square feet (3/8- inch basis), or 59 percent of the total combined production of structural plywood and OSB in 2004. Some design and construction professionals have come to swear by oriented strand board. Others, however, prefer to stick with plywood. So which product is really better? The answer, for most routine construction applications, is both. That’s because both products, although different in composition and appearance, are manufactured according to a set of standards that assure very similar performance when used in applications for which they are intended: sheathing, single-layer flooring, and exterior siding. Manufacturing Process Plywood is composed of thin sheets of veneer or plies, peeled from a log as it is turned on a lathe against a knife blade. The veneer is clipped to suitable width, dried, and graded. Growth characteristics in the veneer, such as knots and knotholes, can be repaired or plugged to improve the grade. Adhesive is applied to the plies, which are then laid up in cross-laminated layers. Plywood has an odd number of layers with each layer consisting of one or more plies. Face layers normally have the grain oriented parallel to the long dimension of the panel. The glued veneer assembly is placed in a hot press where they are bonded together under heat and pressure. -
Woodworking Joints.Key
Woodworking making joints Using Joints Basic Butt Joint The butt joint is the most basic woodworking joint. Commonly used when framing walls in conventional, stick-framed homes, this joint relies on mechanical fasteners to hold the two pieces of stock in place. Learn how to build a proper butt joint, and when to use it on your woodworking projects. Basic Butt Joint The simplest of joints is a butt joint - so called because one piece of stock is butted up against another, then fixed in place, most commonly with nails or screws. The addition of glue will add some strength, but the joint relies primarily upon its mechanical fixings. ! These joints can be used in making simple boxes or frames, providing that there will not be too much stress on the joint, or that the materials used will take nails or screws reliably. Butt joints are probably strongest when fixed using glued dowels. Mitered Butt Joint ! A mitered butt joint is basically the same as a basic butt joint, except that the two boards are joined at an angle (instead of square to one another). The advantage is that the mitered butt joint will not show any end grain, and as such is a bit more aesthetically pleasing. Learn how to create a clean mitered butt joint. Mitered Butt Joint The simplest joint that requires any form of cutting is a miter joint - in effect this is an angled butt joint, usually relying on glue alone to construct it. It requires accurate 45° cutting, however, if the perfect 90° corner is to result.
