This book was released on 1997-01-01 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the aftermath of recent earthquakes in populated areas, observations of wood- frame residential and commercial construction have revealed damage to plywood shear walls in the form of splitting of the sill plate along the line of anchor bolts in the foundation and of the end post along the bolts in the hold-down connection. This paper presents an experimental investigation of the sill plate connection, using a variety of bolt sizes and member thicknesses. The investigation also includes full-scale studies of plywood shear wall assemblies. Standard connections are examined as well as connections strengthened with reinforcing clamps. These clamps are shown to increase strength and energy absorption in wood-to-concrete and wood-to-wood connections where the failure mode is splitting of the wood member. The reinforcing clamps are shown to increase the stiffness and energy dissipation of a shear wall specimen.

Book Synopsis Measurement of Load Distribution in Multiple-Bolted Wood Connections by : JW. Stelmokas
Download or read book Measurement of Load Distribution in Multiple-Bolted Wood Connections written by JW. Stelmokas and published by . This book was released on 1997 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Load distribution behavior among multiple-bolts was evaluated using new, instrumented bolt-type connectors. The instrumented shear bolts output an electronic signal proportional to the shear forces transmitted through the bolt in a double-shear connection during loading. Double-shear connections constructed of clear, straight-grained yellow-poplar (Liriodendron tulipifera) were tested in compression parallel to grain. Five different bolt patterns were used to analyze the effect of number of bolts in a vertical row and number of bolts in a horizontal column on load transfer among the bolts. The load distribution among the bolts in the multiple-bolted wood connection was determined effectively using the shear bolts that provided detailed quantitative data concerning which bolt was the major load carrier throughout the entire test and exactly if and when the load was transmitted between the bolts.

Book Synopsis Structural Fire Performance of Bolted Glulam Beam-to-column Concealed Connections by : Adam Petrycki
Download or read book Structural Fire Performance of Bolted Glulam Beam-to-column Concealed Connections written by Adam Petrycki and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent increased interest in the application of engineered-wood products, such as glued-laminated (glulam) timber and cross-laminated timber (CLT), in the Canadian building construction market has prompted amendments to be made to the building codes of several provinces. Until recently, the National Building Code of Canada (NBCC) restricted the use of wood as the primary building structural systems' material by limiting its application to buildings up to only four storeys. The current version of the National Building Code of Canada, NBCC 2015, increased the height restriction to six storeys. The experimental research study detailed in this thesis has been carried out to investigate the behaviour of concealed steel-glulam bolted connections subjected to monotonic loading at both ambient and elevated temperatures. At ambient temperature, sixteen full-size test assemblies were examined, representing a total of thirty-two tested beam-to-column glulam bolted connections. The connections in eight of the test assemblies were strengthened perpendicular to the wood grain with long self-tapping screws (STS). For both unstrengthened and strengthened connections, increasing the number of bolt rows, each row having two bolts, from two to three rows increased the connection's moment capacity with increments more than that obtained by increasing the bolt's end distance from four to five-times bolt diameters. STS-strengthened connections failed in a relatively ductile manner in contrast to the unstrengthened connections. Increasing the number of bolts to six bolts in three rows in strengthened connections reduced the occurrence of brittle failure modes compared to connections with four bolts in two rows. Critically, STS-strengthened connections experienced increased moment-resisting capacity between 1.3 and 2.4 folds. The results of the ambient tests were used to verify the calculated moment capacities of the test assemblies in order to determine the full-service design load of the connection exposed to CAN/ULC-S101 standard fire in the large-size fire testing furnace accommodated at Lakehead University's Fire Testing and Research Laboratory (LUFTRL). Outcomes of the fire resistance tests revealed that increasing the number of bolt rows from two to three, each of two bolts, increased the glulam beam-to-column connection's fire resistance time by greater increments than those achieved by increasing the bolt's end distance from four to five-times bolt diameter. Strengthened connections were found to have an increased fire resistance time compared to unstrengthened connections. Also, the STS strengthening increased the fire resistance time of the glulam connections by greater increments than those obtained by increasing the number of bolt rows and the bolt's end distance.
Book Synopsis Investigating the Response of Bolted Wood Connections Subjected to Bast Loads by : Andrew McGrath

Available in PDF, EPUB and Kindle. Book excerpt: With recent improvement in wood manufacturing technologies, taller and larger wooden structures are being constructed, thereby increasing the risk for potential damage due to a blast threat against such structures. Recent studies on the effects of high strain rate in wood have been undertaken, however the vast majority of these studies have focussed on structural elements with idealized boundary conditions. Some studies included realistic connections as the boundary conditions, but little progress has been made to date in order to quantify the behaviour of connections in isolation. The current study aims to investigate the response of steel-wood-steel bolted connections when subjected to blast loads. This includes determining the dynamic increase in resistance and stiffness for stocky and slender bolts in both the parallel and perpendicular to grain directions. The study also explores analytical solutions to predict the joint behaviour and discusses the validity of current blast design provisions. Bolted wood connections were investigated under both static and simulated blast loading using the University of Ottawa's shock tube. The study found a dynamic increase in resistance and stiffness when the failure mode was dominated by wood crushing in both the parallel and perpendicular to grain directions. No increase in resistance or stiffness was observed when bolt yielding dominated the failure. A loss of ductility was observed under dynamic loading for the parallel to the grain connections designed to fail in wood crushing. It was found that the use of self-tapping screw reinforcement was an effective method of preventing premature splitting failures and enhancing the performance of a connection. The results showed that connections which engaged the fastener in bending exhibited more favourable behaviour than connections which engaged only in wood crushing. A two degree-of-freedom model was capable of modelling the connections even when the support frame system had some flexibility. The validated model was used to investigate cases where the connection could contribute to the energy dissipation. It was found that the performance of the assembly improved when the connections were considered. Recommended future work includes an investigation of brittle failure modes in bolted connections, exploring connections with more deformation capacities, and expanding the experimental component of the study to include full-scale structural assemblies with wood elements and boundary connections. Limited design recommendations have been proposed in the current study, however testing at the assembly level could shed more light on such an important topic.
