This book was released on 2024-05-13 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current design rules for timber joints with dowel-type fasteners require input parameters such as yield moment and withdrawal capacity, which are determined within the European framework of certification testing. Databases containing these data were assembled. A large scatter was observed. Bespoke series may deliver clear trends. If representative data is considered, these clear trends vanish. Globally valid regression equations are conservative leading to incorrect prediction of failure modes.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies were made of two-member wood joints fastened with nails, bolts, or lag screws and subjected to lateral-impact loads. These studies established a relationship, which is independent of the type of metal fastener, between magnitude of impact force, joint slip, fastener diameter, and specific gravity of wood (Douglas-fir) members. Electronic instrumentation was employed to measure and record the instantaneous forces that were applied to joints in both pendulum and drop tests. Three types of fasteners were tested: Eight-, sixteen-, and thirty-penny nails: 1/4-, 1/2-, and 3/4-inch bolts; and 5/16-, 1/2-, and 3/4-inch lag screws. The work was done in cooperation with the U.S. Air Force, and will be the basis for revised load ratings for metal fasteners in a new blocking and bracing guide. (Author)

This book was released on 1980 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: When bolts or timber connectors are used in a row, with load applied parallel to the row, load will be unequally distributed among the fasteners. This study assessed methods of predicting this unequal load distribution, looked at how joint variables can affect the distribution, and compared the predictions with data existing in the literature. Presently used design procedures were also assessed. The analytical methods were found to predict proportional limit loads but not joint strength. (Author).

Download or read book Design Transactions written by Bob Sheil and published by UCL Press. This book was released on with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design Transactions presents the outcome of new research to emerge from ‘Innochain’, a consortium of six leading European architectural and engineering-focused institutions and their industry partners. The book presents new advances in digital design tooling that challenge established building cultures and systems. It offers new sustainable and materially smart design solutions with a strong focus on changing the way the industry thinks, designs, and builds our physical environment. Divided into sections exploring communication, simulation and materialisation, Design Transactions explores digital and physical prototyping and testing that challenges the traditional linear construction methods of incremental refinement. This novel research investigates ‘the digital chain’ between phases as an opportunity for extended interdisciplinary design collaboration. The highly illustrated book features work from 15 early-stage researchers alongside chapters from world-leading industry collaborators and academics.

Download or read book Stiffness of Bolted Timber Connection written by Nur Liza Rahim and published by . This book was released on 2019 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stiffness equation for connections using fasteners in Eurocode 5 is specified as a function of wood density and fastener diameter only. In this research, an analysis of available data sets on various configurations of tested bolted steel-wood-steel (SWS) connections loaded in tension parallel to grain has been undertaken in order to predict the initial stiffness of each connection. From the analysis, it is indicated that the stiffness equation specified in Eurocode 5 for bolted SWS connections does not adequately predict the initial stiffness. There is a need to incorporate other connection parameters such as the geometry of the connection into the equation to improve accuracy. Furthermore, in this research, numerical model has been developed in ABAQUS to study the stiffness of bolted timber connections loaded parallel-to-grain. From this model, numerical predictions of the stiffness values have been made for various densities, bolt diameters, end distances, row and bolt spacings and thicknesses of the timber members. An analysis of the results has shown that the stiffness of SWS timber connections is strongly dependent on the wood density, fastener diameter, bolt spacing, end distance and thickness of timber member where the greater the density, diameter, bolt spacing, end distance and thickness of timber member, the higher the stiffness value of the bolted timber connection. A relationship for the determination of bolted connection stiffness as a function of the SWS connection configuration is presented by using multiple linear regression (MLR). In order to validate the proposed design equation, tests on 50 timber specimens (40 glued laminated timbers and 10 laminated veneer lumbers (LVL)), with steel plates, were undertaken. The number of bolts was kept the same and the connector diameter, timber thickness, and wood density were varied. The results obtained in the experimental tests are compared with those obtained from the design model. A more comprehensive validation has been accomplished by comparing predictions from the proposed equation and the Eurocode 5 equation with experimental tests from other researchers. From the comparison made, the effectiveness of the proposed design equation to predict the bolted connection stiffness was confirmed. Based on the analysis undertaken, the accuracy of the predictions is discussed and the proposed equation provides a better approximation of the initial stiffness for SWS connections than the current Eurocode 5 design provisions.

Download or read book Timber Fasteners written by Joseph J. Mack and published by . This book was released on 1979 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber fasteners are made in a wide variety of types. In addition to nails, screws and bolts - the traditional metal devices for jointing timber - there are a number of different types of fastener for joints of high strength and stiffness. Even the common nail, as a result of research and development, is now made in many varieties to satisfy special requirements. The choice of fastener depends on many factors. These include the initial cost of the fastener and the cost of making the joint, the magnitude and direction of the forces to be transmitted, the overall size and design of the finished article or structural component, and aesthetic considerations. This Note describes the types of fastener most commonly used in Australia. Some of these are in everyday use, while others are employed only when special requirements rule out simpler types. Details are not given here, however, of the various small fasteners developed for particular industries, such as the furniture industry, since these are mostly variations of the main types.
