Trees, and their derivative products, have been used by societies around the world for thousands of years. Contemporary construction tall buildings from timber, in whole or part, suggests a growing interest potential building with wood at scale not previously attainable. As is only significant material that grown, we natural inclination good environment. But under what conditions this really case? The environmental benefits using timber are straightforward; although it product, large amount...
Bamboo is a rapidly renewable material that has many applications in construction. Engineered bamboo products result from processing the raw culm into laminated composite, similar to glue-laminated timber products. These allow be used standardised sections and have less inherent variability than natural material. The present work investigates mechanical properties of two types commercially available – scrimber sheets compares these engineered It shown are comparable or surpass timber-based...
Engineered bamboo is increasingly explored as a material with significant potential for structural applications. The comprised of raw processed into laminated composite. Commercial methods vary due to the current primary use an architectural surface material, processing used achieve different colours in material. present work investigates effect two types methods, bleaching and caramelisation, determine on mechanical properties. A comparison other engineered timber products also presented....
Bamboo is a rapidly renewable material that available globally and comparable in strength to modern structural materials. The widespread use of bamboo construction limited by the inherent variability its geometric mechanical properties, lack standardisation. Engineered aims reduce natural processed manufactured into laminated composites. Although composites have properties similar other materials, products are currently architectural applications. A field research on engineering emerging...
Significance Fiber materials have great impact on our daily lives, with their use ranging from textiles to functional reinforcements in composites. Although the manufacturing process of manmade fibers is potentially limited by extensive energy consumption, spiders can readily spin silk at room temperature. Here, we report a class material that based self-assembled hydrogel constructed dynamic host–guest cross-links between polymers. Supramolecular be drawn this The supramolecular fiber...
Here we characterise the thermal properties of engineered bamboo panels produced in Canada, China, and Colombia. Specimens are processed from either Moso or Guadua into multi-layered for use as cladding, flooring walling. We utilise transient plane source method to measure their confirm a linear relationship between density conductivity. Furthermore, predict conductivity three-phase composite material, these products can be described, using micromechanical analysis. This provides important...
Structural sections of laminated bamboo can be connected using methods common in timber engineering, however the different material properties and suggest that behaviour connections two materials would not same. This study investigates dowelled connection, which a connector is passed through hole material, load resisted by shear embedment into surrounding material. Steel dowels were used connection between member steel plate central slot bamboo, this was compared with similar timber. The...
The investigation of natural products for use in construction continues to grow fulfil the need sustainable and locally available materials. Bamboo, being globally rapidly renewable, is an example such a material. Structural engineered bamboo are comparatively low-energy-intensive materials with structural properties sufficient demands modern construction. However, lack appropriate building codes standards barrier engineers architects using This paper describes existing national...
Natural materials are a focus for development of low carbon products variety applications. To utilise these materials, processing is required to meet acceptable industry standards. Laminated bamboo commercial product that currently being explored structural applications, however there gap in knowledge about the effects on chemical composition. The present study utilised interdisciplinary methods analysis investigate composition bamboo. Two common were investigated: bleaching (chemical...
Low carbon construction materials are needed to reduce dioxide emissions in the built environment. Laminated bamboo is an example of such a material. However, be used structural applications, fundamental mechanical properties establish design values architecture and engineering practice. Recent studies on laminated have focused use timber standards for small clear specimens, with little work published structural-scale testing. The presented this paper first study utilise test methods...
Laminated bamboo in structural applications has the potential to change way buildings are constructed. The fibrous microstructure of can be modelled as a fibre-reinforced composite. This study compares results fibre volume fraction analysis with previous experimental beam bending results. link between and stiffness shows that differences previously attributed preservation treatment fact arise due strip thickness. Composite theory provides basis for development future guidance laminated...
Abstract Spider silk is a fascinating material, combining high strength and elasticity that outperforms most synthetic fibers. Another intriguing feature of spider its ability to “supercontract,” shrinking up 50% when exposed water. This likely on account the entropy‐driven recoiling secondary structured proteins water penetrates silk. In contrast, humidity‐driven contraction in fibers difficult achieve. Here, inspired by model, supercontractile fiber (SCF), which contracts original length...
In recent years, there has been a rapid rise in the development of engineered bamboo materials, which have potential to play an important role as alternatives conventional building materials. Despite growing diversity products available on market, international standardization both and their constituent elements is limited, lack universal nomenclature recognized one main constraints developing standards. Similar or identical terminology used interchangeably describe different elements,...

This research project aspires to make truly tall timber buildings a reality. Through combination of theoretical design and physical testing this demonstrates the viability at much greater heights than has previously been possible. By pushing limits designs into realms supertall, sometimes beyond that which is feasible using current materials construction technologies, also sets out requirements for next generation engineered plant-based materials.The collaboration between academics,...
Engineered bamboo is being increasingly explored for structural use in the construction sector. To ensure durability, products such as laminated undergo essential preservation treatment steps during their manufacture. However, effects of hygro-thermal caramelisation and chemical bleaching, two commonly used procedures industry, on surface interfacial properties are not yet known. The latter governs quality final product. Our dynamic wettability studies through contact angle measurements...
Abstract The building and construction sector accounts for around 39% of global carbon dioxide emissions remains a hard-to-abate sector. We use data-driven analysis high-level climate action on reduction in the using 256,717 English-language tweets across 13-year time frame (2009–2021). Using natural language processing network analysis, we show that public sentiments emotions social media are reactive to these policy actions.

Cross-laminated timber shear wall systems are used as a lateral load resisting system in multistory buildings. Walls at each level typically bear directly on the floor panels below and connected by nailed steel brackets. Design guidance for lateral-load resistance of such is not well established design approaches vary among practitioners. Two cross-laminated two-story tested under vertical load, along with pullout tests individual connectors. Comprehensive kinematic behavior obtained from...
