Full textAbstract:
Natural composites, in particular nacre, often combine high strength and toughness thanks to highly ordered architectures and controlled geometries of the reinforcement components. However, combining strength, toughness and resorbability in synthetic materials remains a challenge in particular in the field of bone graft substitutes. In the present study, calcium phosphate-(CaP-)based materials with designed architectures inspired from natural composite materials were achieved. CaP platelets obtained by precipitation in organic medium were first aligned in chitosan matrices by solvent casting in ambient conditions. Efficient strengthening was obtained with 15 vol-% ceramic, reaching cortical bone strength (150 MPa) and preserving good ductility (5 % deformation). In a weak magnetic field, high spatial arrangement without percolation was maintained up to 20 vol-%. With directional freezing, good alignment of the platelets could be pushed up to 50 vol-%. In parallel, in situ recrystallization of CaP blocks in hydrothermal conditions led to hierarchical structures. The strength and the work-of-fracture were enhanced (300%) thanks to a change of failure mode.

This diploma thesis deals with the subject of slenderness bars’ stability assessment, especially in the steel structures. Before the assessment of bars in the frame constructions, we search for the influence of the computational model’s settings on the final result. The initial geometrical imperfections are examined on the model of Euler’s bar. The influence of the rigidity of girders on the poles’ buckling length is examined on the basic frame construction. The buckling lengths are assessed in the comparison with the figures we got from the statistical tables and the computational software. The influence of construction’s initial tilt and its replacement by the system of outer forces is examined on the frame structure. Three-hinged frame structure with variable cross-section member is designed then and the influence of non-linear calculations on the inner forces is studied. In the complex frame assessment, the influence of the number of parts of variable cross-section member on the bars’ buckling length is examined.

Full textAbstract:
The purpose of this study is to investigate the influence of material and geometric nonlinearities occurring in beams, columns and walls of RC frame-wall structural systems when undergoing severe ground excitations. For this purpose, a low-rise RC building is considered with and without walls, and the joining beams and columns are designed with the strong-column weak-beam concept. The dimensions, material properties and the reinforcement amounts are calculated in accordance with the values suggested in design codes. Each structure is analyzed for various levels of applied vertical force and change in wall stiffnesswhere the effect of geometric nonlinearity is considered for each case. Force formulation frame elements with spreading inelasticity over the span are used for the modelling of each beam, column and wall. The coupling of the section forces is obtained by the fibre discretization of the section into several material points. Each section is divided into confined and unconfined regions and appropriate material properties are used for concrete and steel for cyclic loading. Both static pushover and dynamic analyses are performed in order to replicate the worst case scenario for a possible earthquake. From this study, it is concluded that the beams and columns of a frame-wall structural system should be designed carefully for load redistributions resulting from the yielding of the wall in the case of a strong earthquake, thus the design codes should address this situation for both in the retrofit of existing frame buildings with walls and in the construction of new frame-wall type buildings.

Small dimension engineering tubular structures subjected to a complex load system are designed like hollow circular shells. For minimum weight design, the ratio between the shell radius and the thickness has to be as large as possible, but its maximum value is limited by the onset of local buckling. Tubular natural structures subjected to a complex load system have often an outer shell of solid material supported by a low density, compliant core, which makes them more resistant to local buckling. Biomimicking of natural constructions offer the potential to improve the design of small diameter tubular engineering structures. Here, the fabrication technology of biomimicked engineering tubular structures integrating aluminum foam or honeycomb as core material is discussed. A viability analysis is presented including technical performance, cost, utility, and risk assessments. Aluminum compliant core shells have potential for substituting CFRP and aluminum tubular structures in aerospace and high-level sport applications. The case of sailboat masts was considered in detail. Results of our analysis proved that use of honeycomb as core material can lead to a significant reduction of the mast weight. Business opportunities based on this application are discussed.

Full textAbstract:
Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. Instead, EKS prescribed that the load-bearing structures of mono glazed balconies should be determined by the use of nominal fire exposure or a natural fire model. EKS and Eurocode have previously prescribed that the standard temperature-time curve (ISO 834) was to be used when determining the fire resistance of structural elements according to nominal temperature-time curves. But an agreement made between Balkongföreningen and Boverket in 2011, established that the external temperature-time curve could be used for determination of the fire resistance of the structural elements of mono glazed balconies. The external temperature-time curve means a design temperature of the structural members of approximately 680 °C for a fire-resistance class R30, instead of a temperature of 842 °C for the standard temperature-time curve. In 2019, EKS 11 was introduced with a slight change in the regulation. The new regulation specifically implies that building parts placed within glazed balconies should not be considered as external. Due to the formulation in EKS 11, it is no longer possible to use the external temperature-time curve for verification of the fire resistance of structural elements of mono glazed balconies. The formulation says that building parts placed within glazed balconies should not be considered as external, which means that the standard temperature-time curve must be applied. The present research tries to clarify the more reasonable temperature-time curve of the standard fire curve and the external fire curve, or if neither of the curves is realistic. 16 scenarios were analysed in this study. Using CFD simulations in FDS, the adiabatic surface temperature of the structural parts could be established. The adiabatic surface temperatures were then used as input in the FEM calculation program TASEF to calculate the temperatures of structural elements of a mono glazed balcony during a fire. The results imply that the max temperatures of the steel members of the mono glazed balcony analysed are generally lower than the temperatures of the external temperature-time curve. In a worst-case scenario where the structural member is located just adjacent to the fire source, the max temperature can be higher than the temperature of the standard temperature-time curve. The balcony slab reaches max temperatures between the external temperature-time curve and the standard temperature-time curve. The temperature within the slab is below 500 °C at a depth of 15 mm and according to the 500 °C isotherm method presented in SS-EN 1992-1-2, concrete that has a temperature lower than 500 °C has not been damaged by the fire. Further studies are needed to establish whether the external temperature-time curve or the standard temperature-time curve is to be used when designing the fire resistance of the load-bearing structure of mono glazed balconies. A suggestion for further studies is to conduct fire tests of a fire within a mono glazed balcony. Such results could then be compared to the results of this study and hopefully, lead to conclusions that are needed for a complete establishment of which temperature-time curve that should be used.Under det tidigare gällande regelverket boverkets konstruktionsregler, BKR, dimensionerades brandmotståndet för den bärande konstruktionen av enkelinglasade balkonger med testmetoden SP fire 105. När BKR ersattes av boverkets föreskrifter och allmänna råd om tillämpning av europeiska konstruktionsstandarder, EKS, tillsammans med Eurokoderna, slutade man att använda SP fire 105 och började istället använda nominella temperatur-/tidförlopp. I tidigare versioner av EKS föreskrevs det att dimensionering enligt klassificering ska utföras med en brandexponering enligt standardtemperatur/-tidkurvan (ISO 834). Men i och med upphörandet av BKR år 2011, genomfördes en överenskommelse mellan Balkongförening och Boverket där man bestämde att den bärande konstruktionen för enkelinglasade balkonger och öppna balkonger skulle få dimensioneras med exponeringskurvan för utvändig brand istället för standardtemperatur-/tidkurvan. Dimensionering enligt exponeringskurvan för utvändig brand resulterar i en dimensionerande temperatur på 680 °C för brandteknisk klass R30, istället för en temperatur på 842 °C vid dimensionering med standardtemperatur-/tidkurvan. Vid införandet av EKS 11 år 2019 skedde en förändring i föreskrifterna gällande branddimensionering av bärande konstruktioner. I EKS 11 framgår det explicit att byggnadsdelar vilka är placerade inom inglasade balkonger inte bör betraktas som utvändiga byggnadsdelar. Detta medför att den bärande konstruktionen för enkelinglasade balkonger inte längre kan dimensioneras enligt exponeringskurvan för utvändig brand, utan måste dimensioneras enligt standardtemperatur-/tidkurvan. Denna studie syftar till att klargöra vilken temperatur som är rimlig att använda vid dimensionering av den bärande konstruktionen för enkelinglasade balkonger. Är den tidigare exponeringskurvan för utvändig brand mer rimlig, eller är föreskriften om att använda standardtemperatur-/tidkurvan motiverad? I studien har 16 scenarion analyserats med hjälp av CFD beräkningar i simuleringsprogrammet FDS, och med hjälp av FEM beräkningar i simuleringsprogrammet TASEF. Med FDS beräknades den adiabatiska yttemperaturen för den bärande konstruktionen, vilken sedan användes som indata i TASEF för att beräkna temperaturen i den bärande konstruktionen. Maxtemperaturen på konstruktionselementen som utgörs av stål uppnår generellt temperaturer som understiger temperaturen för exponeringskurvan vid utvändig brand. I ett ”worst-case” scenario där brandkällan står i direkt anslutning till en stålkonstruktion, kan temperaturer uppnås vilka överstiger temperaturen i standardtemperatur-/tidkurvan. Maxtemperaturen på balkongplattan är högre än temperaturen i exponeringskurvan vid utvändig brand, men lägre än temperaturen i standardtemperatur-/tidkurvan. 15 mm in i balkongplattan understiger temperaturen på betongen 500 °C. Enligt 500 °C isotermmetoden som är publicerad i SS-EN 1992-1-2 innebär detta förenklat att all betong på ett djup överstigande 15 mm har kvar sin fulla bärförmåga. En slutsats är att det krävs vidare studier för att kunna fastställa vilket nominellt temperatur-/tidförlopp som borde användas vid dimensionering av den bärande konstruktionen för enkelinglasade balkonger. Ett förslag på vidare studier är att utföra brandtester på en enkelinglasad balkong, varav resultaten sedan kan jämföras med resultaten i denna studie. Sådana resultat skulle förhoppningsvis möjliggöra ett fastställande av vilket nominellt temperatur-/tidförlopp som bör användas vid dimensionering av den bärande konstruktionen för enkelinglasade balkonger.

Full textAbstract:
Although rice straw and other grains have been used in building since pre-history, in the past two decades, there has been a move to utilize this rapidly renewable, locally available, agricultural byproduct as part of the sustainable construction movement. Up to this point, this has been done by simply stacking up the full straw bales. Stak Block, invented by Oryzatech, Inc., is a modular, interlocking block made of a composite of rice straw and binding agent that serves as an evolution in straw construction. This study investigates the feasibility of using these Stak Blocks as a structural system. The report was divided into four main parts: material testing, development of effective construction detailing, full-scale physical shear wall testing, and a comparison with wood framed shear walls.
The first section investigated the feasibility of using the Stak Blocks in a load-bearing wall application. Constitutive properties of the composite straw material such as yield strength and elastic stiffness were determined and then compared to conventional straw bale. Next, the decision was made to prestress the walls to create a more effective structural system. Various construction detailing iterations were evaluated upon the full-scale shear wall testing using a pseudo-static cyclic loading protocol. Finally, the available ductility of the prestressed Stak Block walls in a lateral force resisting application is quantified along with an approximation of potential design shear forces.
It was determined that the Stak Block material performed satisfactorily in gravity and lateral force resisting applications, in some respects better than conventional wood-framed construction, and has great potential as a seismically-resistant building material.

Full textAbstract:
This thesis discusses the possibilities of using glued laminated timber as load bearing structural elements in structures in close vicinity of saltwater. Glued laminated timber, also referred to as glulam, is a refined timber product constructed of timber lamellae that are glued together. The thesis contains a literature study and a case study that covers glulam beams in a pedestrian jetty located on the Swedish west coast. The literature study addresses wood in relation to moisture, the effects that salt may have on wood in a marine environment, wood decaying mechanisms and suitable wood preservatives to prevent decay. The literature study also covers glulam as a material and the possibilities of wood pressure impregnation. A method of estimating the service life of timber elements is also discussed. The results of the literature study were applied in a case study of a specific case, to explore the possibility of replacing the current steel beams of the structure with glulam beams. From the case study, the strength and deflection of the prospective glulam beams were calculated. Service life of the prospective glulam beams was estimated based on the environment they would be exposed to. An analysis of the market for glulam products in Sweden was also performed to find out what dimensions and wood impregnation classes are available. The results of the literature study show that glulam can be used as main load bearing elements in a marine environment, given that the structure is placed above sea level. Salt water does not affect the wood, rather it works as a wood preservative and gives some protection against rot. However, the structure is subjected to high moisture content and pressure impregnation is necessary. The high moisture content also affects the mechanical properties of the wood as the strength and stiffness of glulam decrease with increasing moisture content. Creep of the material is also affected as it increases with increased moisture content. Regarding strength and deflection, the results of the case study show that glulam beams available on the Swedish market are of sufficient dimensions to be used. Regarding service life, the case study showed that the estimated service life of the glulam beams is only 19 years, but the service life required is 50 years. The current structure design with prospective glulam beams does not meet the requirements for durability of the material. However, suitable design changes regarding wood moisture protection could increase service life of the glulam beams.Denna rapport behandlar möjligheterna till att använda tryckimpregnerat limträ som huvudbärverk i konstruktioner i nära anslutning till saltvatten. Limträ är en träprodukt bestående av trälameller som limmats samman till större träelement. Rapporten består av en litteraturstudie och en fallstudie som behandlar limträbalkar i en promenadbrygga belägen på den svenska västkusten. Litteraturstudien avhandlar trä i förhållande till fukt, eventuell påverkan av salt i en marin miljö, nedbrytningsmekanismer för trä samt lämpliga träskydd för att förhindra nedbrytning. Litteraturstudien behandlar även limträ som material och möjligheterna till tryckimpregnering. En metod för att uppskatta livslängden av trä diskuteras också. Resultaten från litteraturstudien applicerades i en fallstudie för ett specifikt fall, för att undersöka möjligheterna att ersätta den nuvarande konstruktionens stålbalkar med limträbalkar. Utifrån fallstudien beräknades hållfastheten och nedböjningen av de tilltänkta limträbalkarna. Livslängden på de tilltänkta limträbalkarna uppskattades baserat på den miljö de skulle komma att utsättas för. En analys av marknaden av tryckimpregnerade limträprodukter i Sverige genomfördes också för att se vilka dimensioner och tryckimpregneringsklasser som finns att tillgå. Resultatet från litteraturstudien visar att limträ kan användas som huvudbärverk för marina konstruktioner med kravet att konstruktionen placeras ovanför vattenytan. Saltvatten påverkar inte träet negativt utan verkar snarare som träskydd mot röta. Dock utsätts konstruktionen för hög fuktkvot och måste därför tryckimpregneras. Det höga fuktinnehållet påverkar även de mekaniska egenskaperna av träet då hållfastheten och styvheten av limträet minskar med ökande fuktkvot. Krypningen av träet påverkas också, då krypning ökar med ökad fuktkvot. Med avseende på hållfasthet och nedböjning visade resultatet av fallstudien att tryckimpregnerat limträ som kan erhållas från den svenska marknaden är av tillräckliga dimensioner för att kunna användas. Avseende livslängd visade fallstudien att den undersökta konstruktionens estimerade livslängd endast är 19 år. Dock är den erfordrade livslängden för träkonstruktionen 50 år. Dagens konstruktion möter inte kraven på materialets varaktighet, men längre livslängd skulle kunna erhållas genom lämpliga designändringar avseende limträbalkars skydd mot fukt.
