Resumen
A rational procedure for determining the strength of braced timber columns is presented. The theoretical development takes into account the effects of interlayer slip, a phenomenon characteristic of systems with nonrigid connections. Forty-five braced wood columns were fabricated and tested. Very good agreement was observed between experimental results and theoretical predictions. As a measure of efficiency, the braced column results are compared with equivalent layered and equivalent solid systems. Key words: buckling, columns, nails, braced columns, structural engineering, nonrigid connections, timber construction, wood columns, layered, solid.

Resumen
Background:Solid-web I-joists are some of the most commonly used engineered wood products in residential and commercial buildings for floor and roof assemblies. Web openings, which are required to accommodate services in a building, can reduce the shear capacity and structural integrity of the joists. Open-web joists, which do not require modifications on-site, can overcome this problem.Objective:The objective of this study is to create an all-timber open-web joist product utilising engineered timber with reduced environmental impact compared to existing I-joist products. Joists are manufactured by combining latticed web-components made from Laminated Veneer Lumber (LVL) with solid timber flanges. The structural performance of these novel joists is investigated.Methods:Bending and shear tests were carried out on latticed LVL-webbed I-joists of two different depths, namely, 241 mm and 305 mm. The load-displacement behaviour and failure mode were recorded. The characteristic bending moment and shear force capacity are compared to that of commercially available I-joist products manufactured with a solid web.Results:Failure of the I-joists was found to occur in the web, good load capacities were achieved and the response was predominantly linear elastic to failure. Joists manufactured using PRF adhesive were found to outperform those manufactured using UF adhesive.Conclusion:The latticed LVL web I-joists compared favourably with similar-sized solid-web I-joists with regard to moment and shear capacity and have been shown to be a suitable alternative to commercially available I-joists that can also facilitate openings for services without adversely affecting the structural integrity of the joist.

Resumen
Wood is being used extensively in timber construction in China. It is important to understand its response when exposed to elevated temperatures. In fire-resistant design for timber construction, the main goal is to ensure that enough structural integrity is maintained during a fire to prevent structure collapse. To study the effect of temperature on bending strength (MOR) and stiffness (MOE) of solid clear wood from Chinese larch, a total of 108 samples with various target temperatures were tested in static bending under same temperatures to ensure the wood temperature to be sustained. The results indicated that exposure to sustained temperatures caused significant degradation of bending strength and stiffness. The degradation of chemical composition of larch wood happened after 170 °C and caused a serious drop in mechanical properties of larch wood after 225 °C. The bending strength and MOE of larch wood behaved negative linear relationship with temperatures before 100 °C.

Resumen
A rational procedure for determining the strength of spaced timber columns is presented. The effect of interlayer slip, characteristic of layered systems with nonrigid connections, is considered in the theoretical development. A good agreement is observed between the theoretical predictions and experimental results of some 110 spaced columns. The effect of number of spacer blocks on column strength is investigated, and efficiency of various types of spaced columns is compared, first with respect to each other and then with respect to equivalent solid and layered systems. Finally, the theory is compared with design specifications given by CSA Standard CAN3-086-M80, "Code for engineering design in wood." Key words: bolts, buckling, columns (supports), design practice, efficiency, nails, nonrigid connection, spaced columns, split ring connectors, strength, structural engineering, tests, theory, timber construction.

Resumen
Based on acoustic spiral metasurface, a spiral structural layer was designed to apply to timber construction interior wall. The sound absorption coefficient was measured by impedance tube method and compared with Helmholtz resonance structural layer, solid structural layer and air layer in traditional wall. The results show that the combination of the spiral structural layer and the wall can optimize the sound absorption performance of the wall in the medium and low frequency. Without reducing the overall sound-absorbing performance of the wall, can achieve perfect sound absorption in some medium and low frequency sound bands.

Resumen
The interest in replacing native wood with fast growing reforestation wood is recurrent, aiming at larger quantities of material in less time with no losses in its resistive properties. This paper consists in comparing the behavior of in natura structural timber parts with glued laminated timber, made with polyurethane resin based on castor oil, with regard to the resistance to axial compression. The assembly process of these pieces aims to achieve a similar or even superior resistance to the solid ones, considering that the MLC method allows the construction of structural pieces of many sizes and formats using different pieces of wood. Two this end, two species of wood, Pinus and Eucalyptus will be compared. The polyurethane resin, manufactured by the company Imperveg, was used in the process of glueing the stacks together. Evaluations will be performed according to NBR7190 (1997) aiming to characterize the physical and mechanical properties of the pieces and the results obtained will be submitted to statistical analysis by the Anova method.

Resumen
Under de så kallade rekordåren mellan 1961-1975 byggdes det totalt 920,000 lägenheter i flerbostadshus i Sverige, och idag finns omkring 850,000 av dessa kvar. Den vanligaste byggnadstekniken under perioden var med byggande av förtillverkade våningshöga fasadelement tillsammans med en platsbyggd bokhyllestomme med tvärgående bärande innerväggar och gavlar. Syftet med arbetet är att kontrollera om en våningspåbyggnad på ett referenshus från miljonprogrammet med bokhyllestomme är möjlig för att skapa nya lägenheter som medför ökade hyresintäkter för fastighetsägaren, och kan medverka till ökad variation i området arkitektonisk och öka lägenhetsutbudet. Arbetet ger information om vad som behöver kontrolleras och utredas vid uppstarten av ett påbyggnadsprojekt. Arbetet jämför och beskriver tre olika stomförslag på en våningspåbyggnad. Alternativen som tas upp är massivträstomme med bärande flerskiktskiva, prefabricerad betong – och stålstomme bestående av HD/F-plattor och VKR-pelare, och ett alternativ bestående av volymelement. Inventering av konstruktionen och bärförmågan hos den befintliga stommen visar att det finns bärförmåga kvar att utnyttja. Utförda kontroller undersöker bl.a. bärförmågan hos väggar, grundsulor, samt det befintliga vindsbjälklaget. Kontroller utförs även med hänsyn till stabilitet då byggnaden betraktas som en stel enhet med en fiktiv påbyggnad. Slutsatsen av detta arbete är att en våningspåbyggnad är fullt möjlig på referenshuset. Alternativet med massivträ klarar en fiktiv påbyggnad om tre våningar som valts som exempel i arbetet. Alternativet med en prefabricerad betong och-stålstomme kan maximalt byggas på med två extra våningar, sedan blir grundtrycket dimensionerande och begränsar antalet våningar för påbyggnaden till två.
During the so called ‘record years’ between 1961-1975 a total of 920,000 apartments were built in apartment buildings in Sweden. Today about 850.000 of these are still in use. The most common method of building during this period was by using prefabricated one-storey high façade units together with load-bearing interior cross walls and gable walls which were built on site. The purpose of this degree project is to find out if a storey extension on a reference-building from the so called ‘Million Programme’ with load-bearing interior cross walls is possible in order to create new apartments. If this is possible it would give an increase of income of rents to the owner of the apartment building and it could also contribute to an increase of variation in the area as regards both architecture and supply of apartments. This degree project gives information about what has to be checked and investigated before a storey extension project begins. This degree project compares and describes three different suggestions of structural construction systems for storey extensions. The alternatives dealt with are solid timber structural construction consisting of cross-laminated boards, a prefabricated concrete – and steel structural construction consisting of HD/F-elements and tube steel framing, and finally an alternative consisting of prefabricated building modules. The study of the structural construction and the load-bearing capacity of the existing building show that there is enough load-bearing capacity left to make use of. Performed checks investigate for example the load-bearing capacity of load-bearing walls, strip foundations as well as the existing loft floor. Checks are also performed with regard to the stability as the building is considered a stiff unit with a fictitious storey extension. The conclusion from this degree project is that a storey extension is fully possible on the reference-building. The alternative with a solid timber structural construction allows a fictitious storey extension with three additional storeys, which has been chosen as an example in this degree project. The alternative with the prefabricated concrete – and steel structural construction allows a fictitious storey extension of maximum two additional storeys, and then the ground pressure was dimensioning and limited the amount of additional storeys for the storey extension.

Porteous, Alexander. "The structural behaviour of timber joints made with fully overlapping nails". Thesis, Edinburgh Napier University, 2003. http://researchrepository.napier.ac.uk/Output/2787.

Texto completo
Resumen
An integrated programme of experimental and analytical work was carried out to evaluate the nonlinear semi-rigid characteristics of timber connections using fully overlapping nails subjected to short duration lateral loading and moment. The investigation is part of a continuing programme of research at Napier University into the behaviour of timberjoints using fully overlapping nails as the connecting Z -1 mechanism. The effects of the factors and material properties that influence the behaviour of nailed joints were addressed in a structured and controlled way allowing semi-empirical models to be developed for the lateral load behaviour of rnulti-nailed timber joints using steel and plywood gusset plates. A quality control procedure was established for the testing programme and consistent standards were applied to the preparation and testing work. The semi-empirical models that were developed included for the effect of timber density: crussept late material effect- nail strength; number of nails: nail diameter; row spacing and the effect of the moisture content in the timber. They covered joints assembled with and without a gap between the timber and the gusset plates and for joints assembled with steel gusset plates, the effect of the predrill size used in the gusset plate was also investigated. The model results compared very well with the results from tests, accurately predicting the non-linear behaviour of the joints up to failure. An extensive analytical and experimental study was carried out to investigate the moment-rotation behaviour of these types ofjoints. Two linear arýd four non-linear models were developed for each type of joint and the efficiencies of the models were compared to detennine the one that best simulated the joint behaviour. The linear models consistently underestimated the capacity of the joint, giving conservative results. The best solutions were obtained by applying the torsion formula used for steel connections and incorporating the nail behaviour models developed for the non-linear lateral load joints. Account was taken of the non-linear behaviour of the connection and alternative models using fixed and moveable centres of rotation were developed. Very good comparisons were achieved between these models and the test results. A detailed comparison was made between the behaviour of the joints using the lateral load displacement models and Eurocode 5 (EC5) and it was concluded that EC5 rules did not accurately simulate the behaviour of this type of joint. It was concluded that the nail spacing rules in the code did not apply to fully overlapping nails. A limit state design method based on the principles used in EC5 has been developed from the models for the design of joints using fully overlapping nails and subjected to lateral loading or moment. The semi-rigid behaviour of the joints was also investigated and it was concluded that to safely predict the response of structures assembled with fully, overlapping nails. the semi-rigid behaviour must be included for in the analysis procedure. Rigidity factors, end fixing moment reduction factors and the secant rotational stiffness coefficients for the joints were derived. It was also shown that where the analysis was limited to the serviceability limit state. a modified elastic method of analysis could be used and where it was beyond this state a non-linear method of analysis was required.

Resumen
Les projets de construction sont aujourd'hui confrontés à des défis importants pour réduire la grande quantité d'énergie employée quotidiennement pour les utilisations tels que le chauffage, l'électricité et l'eau chaude dans les bâtiments résidentiels et commerciaux, en particulier en Europe. De nombreux règlements de construction encouragent l'utilisation des matériaux biosourcés puisqu’ils semblent avoir des propriétés physiques supérieures en terme d'efficacité énergétique dans le secteur de la construction. L'utilisation de matériaux à faible teneur en carbone dans des structures telles que le béton de chanvre améliore le niveau d'isolation ainsi que l'absorption acoustique et diminue le poids de la structure du bâtiment, car ce matériau naturel fournit un agrégat à faible densité. Cette étude concerne le comportement mécanique de murs en bois, réalisés avec des planches croisées en bois CLT et des murs à panneaux d’OSB, sous l’effet de forces horizontales de cisaillement. Une approche théorique a été proposée pour prédire la performance latérale de la paroi CLT par rapport aux charges latérales ainsi qu’une comparaison entre les résultats théoriques et expérimentaux a été effectuée. Des essais expérimentaux ont été réalisés sur des murs de bois ayant deux formes différentes pour étudier et mettre en évidence les paramètres qui affectent significativement la résistance latérale du béton de chanvre en tant que matériau de remplissage. Des montants verticaux et des éléments de contreventement diagonaux de 2,5 mètres de hauteur et 1,25 mètres de largeur soumis à une compression ont été réalisés dans cette étude . Les résultats ont montré que le béton de chanvre apporte une légère contribution contre les charges latérales dans les murs verticaux de 1,25 mètres de largeur, ce qui signifie qu'une diminution de la largeur du mur de bois diminue significativement la contribution du béton de chanvre contre les charges latérales. Trois murs en bois de différentes longueurs (1,2 mètres, 1,6 mètres et 2,4 mètres) remplis de béton de chanvre ont été étudiés numériquement dans cette étude. D'après les résultats numériques, il était évident que la largeur du mur en bois joue un rôle principal dans la résistance latérale du béton de chanvre : lorsque la largeur du mur augmente, la résistance latérale du béton de chanvre s’accroît considérablement. De plus, le contact et la liaison entre le chanvre et les montants en bois affectent totalement la capacité de la résistance latérale du béton de chanvre en tant que matériau de remplissage dans les murs en bois
Construction projects nowadays face significant challenges to reduce the large amounts of daily energy usage for utilities such as heating, electricity and hot water in residential and commercial buildings – especially in Europe. Many building regulations encourage the use of bio-based materials with superior physical properties for energy efficiency in the construction sector. The use of low-carbon material in structures such as hemp concrete, improves the insulation level and sound absorption and simultaneously decreases the weight of the building structure, as this natural material provides low-density aggregate. This study aimed to investigate the mechanical behaviour of timber frame walls against lateral loads. Cross-laminated timber walls (CLT) and Oriented Strand Board (OSB) were used in this study in order to examine the global lateral strength of timber walls. A theoretical approach has been proposed to predict the lateral performance of CLT wall against lateral loads and a comparison between the theoretical and experimental results has been conducted. Experimental testing was undertaken on a full-size example of two different designs of timber walls to investigate and highlight the parameters that significantly affect the lateral resistance of hemp concrete as infill material. Vertical studs and diagonal bracing elements under compression were used in this study, with dimensions of 2.5m height and 1.25m length. The results showed that hemp concrete makes a slight contribution against lateral loads in vertical stud timber wall of length 1.25m, which means that decreasing the length of timber wall significantly decreased the hemp concrete contribution against lateral loads. Three timber walls with different lengths (1.2m, 1.6m and 2.4m) filled with hemp concrete have been examined numerically in this study. Based on the numerical results, it was obvious that the length of the timber wall plays a major role in the lateral strength of hemp concrete, as increasing the wall length significantly increased the lateral strength of hemp concrete. Also, the contact and bonding between hemp material and timber studs significantly affected the lateral load carrying capacity of hemp concrete as infill material in timber frame walls

Resumen
A classificação estrutural de peças de madeira possibilita melhor utilização do material, separando as peças de acordo com a sua resistência estimada. Nesse processo é feita a classificação visual, de grande importância no caso de madeiras do gênero pinus, e a classificação mecânica por meio de testes não destrutivos com objetivo de estimar o módulo de elasticidade. Com esse objetivo, além de ensaios de flexão estática, podem ser aplicados métodos dinâmicos baseados em medições das frequências naturais e densidade do material para a determinação do módulo de elasticidade da madeira. Nesse sentido o objetivo deste trabalho foi avaliar a eficiência do aparelho portátil Brookhuis Micro Timber Grader (MTG) na estimativa do módulo de elasticidade por meio de ensaios não-destrutivos de vibração longitudinal. Para tanto, foi utilizado um lote de peças estruturais de madeira da espécie Pinus elliottii classificado visualmente. Os resultados obtidos por esse aparelho foram comparados com os resultados de módulo de elasticidade obtidos em ensaio de flexão estática. Tendo em vista a sua praticidade, é recomendável a utilização deste método para a classificação estrutural de peças serradas de madeira. A classificação visual agregada a classificação mecânica são essenciais para a utilização do Pinus em vigas laminadas coladas, construções industrializadas de madeira e do sistema construtivo em woodframe.
The structural grading of wood allows better use of the material, sorting the specimen according to their estimated strength. In this process the visual grading is a fundamental matter in use of the structural Pinus elliottii and also the mechanical grading obtained by non-destructive methods in order to estimate the modulus of elasticity. For this purpose, in addition to the static bending tests, dynamic methods based on measurement of the natural frequencies and density of the material to determining the modulus of elasticity (MOE) of timber can be applied. The objective of this study was to evaluate the efficiency of portable device Brookhuis Micro Timber Grader (MTG) in estimating the modulus of elasticity by non-destructive testing of longitudinal vibration. It was used structural pieces of wood species Pinus elliottii rated visually. The results obtained by this device was compared with the modulus of elasticity results obtained in static bending tests. Given its convenience and low cost, it is recommended to use this method for structural grading of timber sawn pieces. The visual and stress grading are essencial for the use of Pines in glued laminated timber, industrilization timber constructions and woodframe constructions.

Resumen
La mixité bois-béton est une solution intéressante dans le domaine des ouvrages d'art pour la réalisation de ponts, et dans le domaine du bâtiment dans la confection de planchers mixtes bois-béton. Le laboratoire Navier travaille depuis plusieurs années au développement du procédé par collage appliqué aux structures mixtes bois-béton. En effet, cette technique d'assemblage permet d'assurer une connexion quasi-parfaite entre le bois et le béton, contrairement aux techniques d'assemblage usuelles (connecteurs métalliques). Des travaux antérieurs ont montré la bonne performance de structures mixtes collées bois-béton du point de vue de leur tenue mécanique en fatigue. Cependant la connexion par collage nécessite une étude complémentaire concernant la durabilité de l'assemblage collé bois-béton, en particulier lorsque la structure mixte est soumise à des conditions hygrométriques variables. Les travaux menés pendant la thèse ont pour objectifs de déterminer les facteurs qui influent sur la tenue de ces assemblages collés sous chargement hydrique ; ils se divisent en 3 parties :-Deux parties expérimentales :(1)Des tests de cisaillement « Push-Out », en collaboration avec le Laboratoire Départemental d'Autun, ont permis d'évaluer l'effet des propriétés élastiques de l'adhésif sur la tenue en cisaillement de l'assemblage. L'objet de cette étude expérimentale est de valider un choix de colle pour ce type d'assemblage, prenant en compte un vieillissement hydrique, en se basant sur la capacité maximale atteinte en cisaillement, et le mode de rupture de l'assemblage. (2)Parallèlement aux tests de cisaillement, l'effet de chargements hydriques sur la tenue d'assemblages collés bois-béton a été étudié. L'analyse du comportement hydrique de la structure a été réalisée par la technique de corrélation d'image (DIC) sur des assemblages bois-béton collé de petite taille. Ces mesures de déformations locales ont permis de localiser des zones d'endommagement liées notamment aux déformations hydriques du bois empêchées par l'interface collée. Les effets des propriétés élastiques de l'adhésif, de la géométrie du bois (notamment sa structure et le sens des cernes par rapport au plan de collage) ainsi que du comportement mécanique du matériau cimentaire ont été étudiés.- Une partie numérique :(3) Un modèle numérique par éléments finis a été validé en comparant les résultats numériques aux cartes de déformation obtenues expérimentalement. L'analyse numérique a permis de quantifier les contraintes induites au niveau de l'interface en relation avec les déformations hydriques empêchées par l'interface collée et de prévoir le comportement à l'échelle 1 de structures mixtes. Ces différentes investigations ont permis de proposer des solutions optimisant ce type de connexion et de définir des conditions de mise en œuvre et d'utilisation de ces assemblages
The wood-concrete composite is an interesting solution in the field of Civil Engineering to create high performance bending elements for bridge, as well as in the building construction for the design of wood-concrete floor systems. The Navier laboratory has been working for many years on the development of the bonding process as applied to wood-concrete composite structures. Contrary to conventional joining connectors (metal connectors), this assembling technique does ensure an almost perfect connection between wood and concrete. Previous work has already shown good performances of glued wood-concrete composite structures in terms of mechanical fatigue. However, the bonding connection requires additional research on the long-term behaviour of glued wood-concrete composites, especially when this structure is subjected to variable hygrometric conditions. The work undertaken during this thesis aims at determining the factors which induce damages on these glued wood-concrete assemblies under hygrometric loading; the research is divided into 3 parts:-Two experimental parts:(1)"Push-Out" shear tests conducted in collaboration with the Departmental Laboratory of Autun, were used to assess the effect of the elastic properties of the resin on the shear strength of the assembly. This experimental study aims at validating the adhesive of choice for this kind of connection, taking into account ageing under variable hygrometric conditions. Analysis is based on maximum shear capacity and on the failure mode of the assembly. (2)In addition to shear tests, the effect of hygrometric loading on the durability of glued wood concrete assemblies was examined. The analysis of the hydric behaviour of the structure was carried out by the digital image correlation (DIC) technique on small-sized glued wood-concrete assemblies. The measurements of the local deformations allowed us to locate areas of damage, particularly due to the hydric deformations of the wood prevented by the glued connection The effects of the elastic properties of the resin, the microstructure of the wood (including its structure and the direction of the annual rings) as well as the mechanical behaviour of the concrete material were examined.- A numerical part:(3) A numerical finite element model was validated by comparing the numerical results to the deformation maps experimentally obtained. Numerical analysis was used to quantify the stresses induced to the structure, in relation to hydric deformations prevented by glued connection. Moreover investigations at the full scale were conducted to evaluate the long-term behaviour under variable hygrometric conditions. These investigations were conducted in order to offer solutions aiming at optimizing this type of connection, and to define conditions for use of these glued assemblies

Resumen
<p>Since the dawn of civilization, timber has been a primary material for achieving great structural engineering feats. Yet during the late 19th century and most of the 20th century it lost currency as a preferred material for construction of large and tall multi-storey building superstructures. This Structural Engineering Document (SED) addresses a reawakening of interest in timber and timber-based products as primary con-struction materials for relatively tall, multi-storey buildings. Emphasis throughout is on holistically addressing various aspects of performance of complete systems, reflecting that major gaps in knowhow relate to design concepts rather than technical information about timber as a material. Special con-sideration is given to structural form, fire vulnerability, and durability aspects for attaining desired building performance over lifespans that can be centuries long.</p>

Resumen
AbstractNon-structural or out-of-grade timber framing material contains a large proportion of visual and natural defects. A common strategy to recover usable material from these timbers is the marking and removing of defects, with the generated intermediate lengths of clear wood then joined into a single piece of full-length structural timber. This paper presents a novel workflow that uses machine learning based image recognition and a computational decision-making algorithm to enhance the automation and efficiency of current defect identification and re-joining processes. The proposed workflow allows the knowledge of worker to be translated into a classifier that automatically recognizes and removes areas of defects based on image capture. In addition, a real-time optimization algorithm in decision making is developed to assign a joining sequence of fragmented timber from a dynamic inventory, creating a single piece of targeted length with a significant reduction in material waste. In addition to an industrial application, this workflow also allows for future inventory-constrained customizable fabrication, for example in production of non-standard architectural components or adaptive reuse or defect-avoidance in out-of-grade timber construction.

Resumen
Engineered wood products are considered as best building materials due to environmentally friendly. Huge change to the way in which wood has been utilized in primary application of construction in the course of the most recent 25 years are in light of decreased admittance to high strength timber from growth forests, and the turn of events and creation of various new design of manufactured wood products. Engineered wood products are available in different variety of sizes and measurements like laminated veneer lumber, glued laminated timber, finger jointed lumber, oriental strand board etc. It is utilized for rooftop and floor sheathing, solid structure, beams and the hull of boats. This review objectively explores not only the environmental aspects of the use of different engineered wood composites as a building material, but also their economic aspects, to understand their effect on sustainability.

Resumen
The use of solid particles as a heat transfer and thermal energy storage (TES) medium in central receiver systems has received renewed attention in recent years due to the ability of achieving high temperatures and the potential reduction in receiver and TES costs. Performance of TES systems is primarily characterized by the percentage of heat loss they allow over a prescribed period of time. Accurate estimation of this parameter requires special attention to the transient nature of the process of charging the TES bin during solar field operation and discharging during nighttime or at periods where solar field operation is interrupted. In this study, a numerical model is built to simulate the charge-discharge cycle of a small cylindrical-shaped TES bin that is currently under construction. This bin is integrated into the tower of an experimental 300-kW (thermal) central receiver field being built in Riyadh, Saudi Arabia, for solid particle receiver research, most notably on-sun testing of the falling particle receiver concept within the context of a SunShot project. The model utilizes a type of wall construction that had been previously identified as showing favorable structural characteristics and being able to withstand high temperatures. The model takes into account the anticipated charge-discharge particle flow rates, and includes an insulating layer at the ceiling of the bin to minimize heat loss by convection and radiation to the receiver cavity located immediately over the TES bin. Results show that energy loss during the full charge-discharge cycle is 4.9% and 5.9% for a 5-hour and 17-hour discharge period, respectively. While large, these energy loss values are primarily due to the high surface-to-volume ratio of the small TES bin being investigated. Preliminary analysis shows that a utility-scale TES bin using the same concept will have an energy loss of less than 1%.

Resumen
<p>This paper introduces a series of sustainable timber construction using wood-wood connections, which are driven from environmental requirements. These constructions are based on geometries like origami and free-form instead of standard structural elements. In addition, to predict the structural behaviour, the simplified numerical methods for accurately modelling are used. The aim of these case studies is to better explore the value of wood-wood connections as inheritance of ancient culture and extend research on their integration into design processes. Through the design, manufacturing and assembly stage, the connections are investigated as a driver for architectural forms. The utilisation of these innovative connections with minimised metal connectors ensures the rapid, precise and simple assembly process. With in-depth study and innovation of the ancient wood-wood connections, experience in prefabricated timber structure not only offers new geometrical opportunities, but also expands the understanding of integration of ancient and modern cultures.</p>
