“…The reinforced specimens exhibited a less catastrophic failure mode, whereas the non-reinforced specimens failed in a brittle manner; in addition, the reinforced specimens showed greater embedding and ultimate strength. Lam et al (2010) conducted experimental studies on the moment resistance of bolted timber connections. A total of 30 connection tests were performed on specimens with regular connections, with connections reinforced with selftapping screws and with failed regular connections retrofitted with self-tapping screws.…”

Nine cyclic tests were conducted on full-scale one-story, one-bay timber post and beam construction specimens to study the lateral resistance of reinforced glued-laminated timber post and beam structures. Two reinforcement methods, wrapping fiber-reinforced polymer (FRP) and implanting self-tapping screws, and two structural systems, simple frame and knee-braced frame, were considered in the experimental tests. Based on the observed experimental phenomena and the test results, the feasibility of the reinforcement was discussed; the contributions of different methods were evaluated; and the seismic performance of the specimens were studied. The results indicated that both reinforcement methods could limit the crack development and improve the strength, stiffness and energy dissipation capacity. The results also showed that the lateral resistance could be significantly improved by retrofitting a failed simple frame with joint reinforcement and a knee-brace, demonstrating that this approach can be applied in engineering practice.

This study was based on the combination of simple and quick techniques to substitute the conventional manufacturing system assembly of metal truss connected by wood structures for free environments and less movement. Although simple in its use, the bolted connections are extremely complex in their analysis and behavior. The study was based on evaluating bolted wood/wood and wood/wood with a metal divider interface connections, just to observe the strength of the set's performance under real loads of support coming from the roof elements of the work. Load tests to evaluate the shear behavior nonlinear of the connecting bolts were carried out with loads until 10 ton. On prototypes previously dimensioned according to NBR 6120 to determination of the values of the loads, with two, three and four bolts of the type SAE J 429 grade 5. It was observed that the insertion of a metal plate between the pieces of wood increased by about 50% in the shear strength of the connection. The models A 1 and B 1 , with two bolts with or without plate, were the ones with least resistance, while with three bolts were most loads resisted. Simulations with FEMAP-Finite Element Modeling and Post-processing/NASTRAN were performed for comparison.

“…These technologies have improved the moment-resisting capacity and seismic performance of timber joints. [45][46][47] Developing Improved Wood Protection Treatments Wood is widely used in construction in North America, and replacing decayed or moldy wood costs billions of dollars per year. 48 In addition, concerns about decay sometimes prevent wood from being used.…”

Forest-derived biomaterials can play an integral role in a sustainable and renewable future. Research across a range of disciplines is required to develop the knowledge necessary to overcome the challenges of incorporating more renewable forest resources in materials, chemicals, and fuels. We focus on wood specifically because in our view, better characterization of wood as a raw material and as a feedstock will lead to its increased utilization. We first give an overview of wood structure and chemical composition and then highlight current topics in forest products research, including (1) industrial chemicals, biofuels, and energy from woody materials; (2) wood-based activated carbon and carbon nanostructures; (3) development of improved wood protection treatments; (4) massive timber construction; (5) wood as a bioinspiring material; and (6) atomic simulations of wood polymers. We conclude with a discussion of the sustainability of wood as a renewable forest resource. WOOD'S 390 MILLIONTH BIRTHDAYWood is one of the major innovations of land plants ''invented'' some 390 million years ago. Wood enabled individual plants to increase their stature and persistence in the environment, facilitating the ability of trees to play roles in landscape change and biome composition and to fundamentally alter the global cycling of water, minerals, and carbon. Since prehistoric times, humans have found wood invaluable for meeting many of their needs, including energy, tools, and shelter-not surprising given its near-ubiquity, versatility, and renewability. Only in the comparatively recent past have other nonrenewable natural resources, such as fossil fuels or metal ores, become the resources of choice to meet our material needs. We postulate that wood will play an increasing role in the sustainability of our future materials through both expansion of uses for current forest products and development of alternatives to materials currently derived from nonrenewable resources. Life cycle assessments, which categorize energy consumption and emission profiles for products over their whole life cycle, 1,2 consistently show that many wood-based materials use less fossil fuels to produce than do competing materials.3,4 Using wood products can also lower atmospheric carbon dioxide levels because growing forests capture carbon and harvested wood products store the accumulated carbon while in service.Historically, wood research has been the purview of wood technologists; however, we see the future of wood research as interdisciplinary, collaborative, quantitative, and meaningful, both scientifically
