Structural engineering is facing an extraordinarily challenging era. These challenges are driven by the increasing expectations of modern society to provide low-cost, architecturally appealing structures which can withstand large earthquakes. However, being able to avoid collapse in a large earthquake is no longer enough. A building must now be able to withstand a major seismic event with negligible damage so that it is immediately occupiable following such an event. As recent earthquakes have shown, the economic consequences of not achieving this level of performance are not acceptable. Technological solutions for low-damage structural systems are emerging. However, the goal of developing a low-damage building requires improving the performance of both the structural skeleton and the non-structural components. These non-structural components include items such as the claddings, partitions, ceilings and contents. Previous research has shown that damage to such items contributes a disproportionate amount to the overall economic losses in an earthquake. One such non-structural element that has a history of poor performance is the external cladding system, and this forms the focus of this research. Cladding systems are invariably complicated and provide a number of architectural functions. Therefore, it is important than when seeking to improve their seismic performance that these functions are not neglected. The seismic vulnerability of cladding systems are determined in this research through a desktop background study, literature review, and postearthquake reconnaissance survey of their performance in the 2010 – 2011 Canterbury earthquake sequence. This study identified that precast concrete claddings present a significant life-safety risk to pedestrians, and that the effect they have upon the primary structure is not well understood. The main objective of this research is consequently to better understand the performance of precast concrete cladding systems in earthquakes. This is achieved through an experimental campaign and numerical modelling of a range of precast concrete cladding systems. The experimental campaign consists of uni-directional, quasi static cyclic earthquake simulation on a test frame which represents a single-storey, single-bay portion of a reinforced concrete building. The test frame is clad with various precast concrete cladding panel configurations. A major focus is placed upon the influence the connection between the cladding panel and structural frame has upon seismic performance. A combination of experimental component testing, finite element modelling and analytical derivation is used to develop cladding models of the cladding systems investigated. The cyclic responses of the models are compared with the experimental data to evaluate their accuracy and validity. The comparison shows that the cladding models developed provide an excellent representation of real-world cladding behaviour. The cladding models are subsequently applied to a ten-storey case-study building. The expected seismic performance is examined with and without the cladding taken into consideration. The numerical analyses of the case-study building include modal analyses, nonlinear adaptive pushover analyses, and non-linear dynamic seismic response (time history) analyses to different levels of seismic hazard. The clad frame models are compared to the bare frame model to investigate the effect the cladding has upon the structural behaviour. Both the structural performance and cladding performance are also assessed using qualitative damage states. The results show a poor performance of precast concrete cladding systems is expected when traditional connection typologies are used. This result confirms the misalignment of structural and cladding damage observed in recent earthquake events. Consequently, this research explores the potential of an innovative cladding connection. The outcomes from this research shows that the innovative cladding connection proposed here is able to achieve low-damage performance whilst also being cost comparable to a traditional cladding connection. It is also theoretically possible that the connection can provide a positive value to the seismic performance of the structure by adding addition strength, stiffness and damping. Finally, the losses associated with both the traditional and innovative cladding systems are compared in terms of tangible outcomes, namely: repair costs, repair time and casualties. The results confirm that the use of innovative cladding technology can substantially reduce the overall losses that result from cladding damage.

A utilização de tecnologias construtivas inovadoras, como os painéis pré-fabricados arquitetônicos de concreto (PPAC), tem-se configurado prática frequente do mercado brasileiro por, potencialmente, contribuir para incrementar os níveis de industrialização dos processos de produção, bem como a qualidade do produto final a custos reduzidos. No Brasil, entretanto, não existem ainda normas ou manuais técnicos que balizem a utilização dessa tecnologia construtiva. Por isso, este trabalho sistematiza o conhecimento sobre a tecnologia de PPAC para emprego em fachadas de edifícios de múltiplos pavimentos, por meio da apresentação dos principais fatores que devem ser considerados nas fases de elaboração dos projetos de empreendimentos que utilizem os PPAC em suas fachadas. Fatores esses, que condicionam o desempenho e a eficiência do processo de produção das fachadas. Após o acompanhamento do processo de produção de dois empreendimentos que utilizaram PPAC em suas fachadas, constituindo os estudos de caso, conclui-se que a tecnologia de PPAC apresenta grande potencial para incrementar os níveis de industrialização do processo de produção do edifício, se a elaboração dos seus projetos ocorrer nas fases preliminares da concepção do empreendimento, em que suas funções e interfaces sejam consideradas.
The arquitectural precast concrete panel technology has frequently been used because of its probability of increasing the industrialization levels of the building process and also improve the building product quality. On the other hand, mostly in Brasil, there are no rules ou manual books which guide the utilization of this technology. In addition, this works aims to raise the knowledge about the arquitectural precast concrete panel used as cladding (APCP-PPAC in Portuguese). Therefore, this works presents some factors that must be considered in designs of building facades, using this kind of technology. After the analysis of one study case using APCP, it was concluded that APCP technology has a great potential of increasing the industrialization levels of the building process, if its designs are done as soon as possible and if its performance and interfaces are considered.

La robustezza degli edifici industriali, definita come la capacità della struttura di resistere ad azioni eccezionali come eventi sismici evitando un collasso globale, è uno dei principali argomenti di ricerca a causa della grave perdita umana ed economica che causa la mancanza di tale caratteristica. La maggior parte degli edifici industriali esistenti sono stati realizzati con normative senza specifici standard per strutture prefabbricate in cui la progettazione degli elementi costruttivi si basava sulle singole soluzioni progettuali dei produttori. Le strutture industriali prefabbricate italiane esistenti a grandi luci possono essere suddivise in due categorie principali a seconda dell'evoluzione delle tecniche di prefabbricazione. La prima categoria si sviluppa dai primi anni trenta fino alla metà degli anni sessanta con strutture industriali in c.a. gettate in opera con un uso diffuso di volte leggere prefabbricate per coprire ampie luci, mentre la seconda è prodotta a partire dagli anni cinquanta tutt’ora in uso riguardante la tipica struttura a telaio prefabbricato con tutti gli elementi realizzati in stabilimento ed assemblati sul posto. Nelle prime tipologie di edifici industriali, la robustezza è definita considerando diversi stati limite di deformabilità e resistenza di pilastri e travi combinati con la vulnerabilità specifica del sistema voltato prefabbricato, sapendo che la struttura è soggetta ad una combinazione di eventi sismici ravvicinati nel tempo che portano all'accumulo del danno. Nel secondo caso la robustezza della struttura del telaio prefabbricato è solitamente basata sulle connessioni di elementi strutturali e non (pannelli di tamponamento) e nell'attivazione dell'effetto domino passando dal collasso di tipo locale a quello globale. In questo lavoro sono analizzati diversi modelli ad elementi finiti per rappresentare al meglio il comportamento strutturale lineare e non lineare di entrambi i tipi di strutture prefabbricate considerate.
Robustness of industrial buildings, defined as the capacity of the structure to withstand exceptional actions like seismic events avoiding a global collapse, is one of the main topics of research due to the serious human and economic loss that the lack of such feature could cause. Most of the existing industrial buildings are made with precast elements realised with low-code without specific detailed standards for precast structures in which the technical achievement of them relies on the individual producers with their design solutions. Existing Italian precast structures for large-scale industrial buildings can be divided into two main categories depending on the evolution of prefabrication techniques. The first category was developed from the early thirties up to the mid-sixties, with RC industrial structures cast in place with a widespread use of precast vault to cover a large span, while the second one started to be produced at the beginning of the fifties and is still in use as regards the typical precast frame structure with all its main elements made in factory and assembled in place. In the first type of industrial buildings, only the roof is precast and usually made in reinforced hollow brick light-weight vault and the robustness is defined considering several limit states of chord-rotation and shear capacity of columns and main beams combined with specific vulnerabilities of the precast vault, considering that every seismic sequence is usually a combination of a mainshock and several aftershocks which lead to the damage accumulation on the structure. In the second case the robustness of precast frame structures is usually based on the connections of structural and non-structural elements (cladding panels) and on the activation of the domino effect passing from local to global collapse. In this work several finite element models to best represent the linear and nonlinear structural behaviour of both types of precast structures considered are analysed.

O Brasil, no mercado mundial, ocupa lugar de destaque na extração e comercialização das rochas ornamentais e de revestimento, demonstrado pela produção mensal de chapas que é da ordem de 4 milhões de metros quadrados. Dentre suas as diversas formas de aplicações na construção civil, observa-se um incremento do uso em revestimentos de fachadas de edifícios, principalmente nos grandes centros urbanos. A forma de fixação das placas nas fachadas dos edifícios é feita com o auxílio de inserts metálicos, técnica desenvolvida na Alemanha e nos Estados Unidos. O presente trabalho trata da especificação e normatização das rochas ornamentais e, no caso específico dos revestimentos de fachadas, são apresentados diversos aspectos da seleção das placas de rocha e dos inserts metálicos e também o cálculo estrutural de um sistema de revestimento

Nel corso degli ultimi anni sono state condotte analisi e ricerche scientifiche riguardanti l’effetto che i fenomeni sismici hanno in termini di danni economici sulle opere colpite. Da questi studi è emersa l’importanza rivestita dall’aliquota di costo relativa al ripristino de i danni associati agli elementi non-strutturali (o secondari) e/o al contenuto dell’edificio. Questo vale specialmente nel settore industriale in cui, nella quasi totalità dei casi, il valore monetario degli impianti e delle installazioni interne è di gran lunga maggiore rispetto al valore della nuda struttura. Si pensi ad esempio ai danni subiti dalle numerose aziende diffuse nel territorio Emiliano a seguito dei recenti eventi sismici avvenuti nel Maggio del 2012. In questo scenario si inserisce lo scopo principale della presente ricerca, ossia quello di sviluppare una metodologia semplice e affidabile in grado di consentire una stima precisa delle perdite economiche legate ai danni subiti dai terremoti, con particolare riferimento agli edifici prefabbricati industriali. All’interno di questo progetto sono analizzati differenti modelli basati su un approccio probabilistico interdisciplinare che accorpa in sé: l’analisi della pericolosità del sito su cui sorge l’edificio, l’analisi della risposta strutturale, l’analisi del danno subito e la valutazione del costo associato per ogni componente vulnerabile. Partendo dai modelli di calcolo più raffinati, quali il PEER PBEE, si è giunti infine alla messa a punto di due procedure più semplificate e rapide, l’una basata su un approccio agli spostamenti per l’analisi strutturale e l’altra sull’impiego di una formulazione in forma chiusa in alternativa alla procedura raffinata. L’impiego di tali procedure, richiede dapprima l’identificazione delle più comuni vulnerabilità caratterizzanti e riscontrabili negli edifici prefabbricati industriali e successivamente la conoscenza delle curve di fragilità e di costo per tutti gli elementi che possono dare origine ad eventuali perdite economiche. Ad oggi però, la risposta sismica degli elementi non strutturali in edifici prefabbricati e l’interazione degli stessi con la risposta globale della struttura non è completamente definita ed in alcuni casi non è mai stata indagata, per tale motivo è attualmente oggetto di numerosi studi di ricerca. Molto spesso quindi le curve di fragilità e di costo non sono disponibili. Da qui nasce l’interesse d’indagare la risposta sismica nel fuori piano dei pannelli prefabbricati di tamponamento esterno, nonché l’entità delle forze nelle connessioni metalliche pannello-struttura. Oltre a questo è indagata pure l’influenza del carroponte e l’interazione dello stesso con la risposta sismica globale della struttura in edifici prefabbricati industriali in calcestruzzo armato.
During the last few years, several analyses and scientific studies were conducted on existing buildings in terms of economic damages and losses on the affected buildings. These studies showed the importance of the rate of recovery costs associated to the damages of the non-structural elements (or secondary elements) and/or the contents of the building. Especially in the industrial field, in almost all cases the monetary value of the facilities and the internal installations is far greater than the value of the bare structure. Just think about the damages suffered by many companies spread in the Emilian territory following the recent earthquakes that occurred in May, 2012. The main purpose of the current research is framed in this scenario. To achieve this goal, a simple and reliable method capable of allowing an accurate estimation of the economic losses linked to the damage caused by earthquakes on precast reinforced concrete industrial buildings is developed. Within this project, different models of computation are critically studied and analysed. All of these methods are based fundamentally on a probabilistic and interdisciplinary approach, which incorporates: the hazard analysis of the site, the structural analysis, the damage analysis and the loss analysis suffered by each vulnerable component. Starting from the most refined PEER PBEE methodology, this research has led to the development of two more simplified and speedy procedures, one based on a displacement method for performing the structural analysis and the second method uses a closed formula as an alternative to the refined PEER PBEE methodology. The use of such procedures requires the identification of the most common vulnerabilities detectable in precast reinforced concrete buildings, as well as the knowledge of the fragility and the cost curves for all the vulnerable elements which can give rise to possible damages and then the monetary losses. Actually, the seismic response of the non-structural elements in precast reinforced concrete buildings and the interaction of the same with the global response of the structure is not completely defined and in some cases, it has never been investigated. Therefore, very often the fragility and the cost curves of the elements are not available: this is one of the reason why it is the subject of the most recent research studies. From this, the interest to inquire about the seismic response of the out-of-plane performance of the horizontal cladding panels was born. In addition, the influence of the overhead crane in the seismic response of precast buildings is also analysed.

I rapporten har vi skrivit om naturstenens roll och förutsättningar som fasadmaterial inom byggproduktion. Målet med undersökningen var att belysa nya tekniker som finns på marknaden. Metoder som har använts för att undersöka infästningstekniker är genom intervjuer och studiebesök.   Den stora frågan var att ta reda på hur dem nya teknikerna kan påverka vår arbetsmiljö, miljö samt estetik. En annan fråga var hur den nya tekniken kan uppfylla de nya kraven?   Natursten är ett naturligt material som är inhomogen och därför förekommer det färgskiftningar och variationer i stenskivorna. En beställare ska därför vara väldigt specifik när stenen utses.   Det finns en stor risk med att förankra stenskivor utan mekanisk förankring. Utan förankringen kan stenen lossna från fasaden. Idag bygger vi vanligen med tekniken ventilerad luftspalt, mellanrum mellan stenskivor och stomme. På det sättet kan alla stenskivor röra sig utan spänningar samtidigt som luftspalten ventilerar och dränerar ut fukten bakom stenskivorna. Genom att välja lämpliga stendimensioner och ankare i standardutförande kan kostnaderna minskas. Denna rapport tar upp ny teknik. FZP, Fischer Zykon Panel, är ett undercut ankare. Detta är en valmöjlighet om en beställare vill erhålla skivor som är 20 mm i tjocklek.   Björn Shouenborg har designat ett program som gör det möjligt att dimensionera sten på fasader. Programmmet visar om dimensioneringen är ok med hänsyn till säkerhetskraven.   Med tanke på de stora miljökraven som ställs är det både lönande att undersöka möjligheter och ny teknik. Stommen byggs med mer isolering vilket kräver en längre expanderbult eller ankare mellan stenen och stommen.   I denna rapport framkommer det att en arkitekt och stenentreprenör är positiva till ACT-systemet.  Den här rapporten har belyst att den nya tekniken har en positiv påverkan på arbetsmiljön, miljön, estetik och tid.
The report talks about the capacity and conditions as a façade material within building construction. The goal with the research was to shed light on the new technique available today.  The methods used to examine the mechanical anchoring techniques were through interview and fieldstudies. The main question was to find out how those new technologies can affect our health and safety, environment and aesthetics. Another question is how the new technology can meet the new requirements?   Natural stone is a natural material that is inhomogeneous and therefore there are color variations and variations in stone tiles. A client should therefore be very specific when the stone is appointed. There is a great risk to anchor stone tiles without mechanical anchoring, without it the stone can detach from the façade. The technology most commonly used in anchoring stone is using a ventilated air gap, a space between the stone tiles and facade. In this way, all stone tiles move without tension and furthermore the air gap ventilates and drains the moisture behind the stone tiles. It is possible to cut costs by choosing the appropriate stone dimensions and tiles in the standard execution. New technology opens up new possibilities. An alternative is FZP, Fischer Zykon Panel which is an undercut anchor. This could be used as an option if a client wishes to have 20 mm thick tiles. Bjorn Shouenborg, researcher, has designed a program that makes it possible to dimension stone facades.The software that shows if the design is ok with regard to safety requirements.   Given the large environmental requirements imposed today, it is conceivable both be worthwhile to explore the possibilities and new technologies. The façade is built with more insulation which requires a longer expansion of anchors.   In this report, it appears that an architect and stone contractor is positive for the ACT system. This report has highlighted that the new technology has a positive impact on the work environment, the environment, aesthetics and time.

This thesis deals with the design and elaboration process of a project documentation of a sports centre. The designed sports centre building is situated in the southern part of the town of Polička, in the area determined for sports and free time activities complexes and areas. It is a two-floor, non-cellar, flat-roof building. It is based on plain concrete strip foundations and reinforced concrete foundation footing. The bearing, peripheral and partition walls are designed from POROTHERM hollow clay blocks. Reinforced concrete columns are designated in open disposition areas. The ceiling construction is made from SPIROLL pre-stressed concrete floor slabs and point-supported reinforced concrete slabs. The peripheral walls of the first aboveground floor are insulated with external thermal insulation system with a protective gabion facade. The peripheral wall thermal insulation in a bowling restaurant and gym halls extension is designed from a ventilated facade with CEMBRIT METRO facade cladding panels. The building is functionally divided into two main parts with a shared entrance. The sports centre with gyms and other sports facilities form the first part. Three squash courts, a mini-football piste, a special room for spinning and alpinning, a room for group exercising and cloakrooms with sanitary facilities are designed within one part of the sports centre. A restaurant with a bowling area and a kitchen with storerooms and other facilities for employees form the second part. The designed complex is barrier-free. There is aimed to be a car park for fifty cars, four motorbikes and a bus in front of the building. Three parking places are for disabled people.

The envelopes are in the administrative part and the part of the station divided by a glazed area. In the workshops and technology room the envelope is divided by lamellae. Usually there are 13 firemen during one shift, in three shifts there work 39 firemen all together. There are supposed to be 17 employees in the administrative department.

The design of “non-structural” elements, including the cladding panels for precast RC buildings, plays a key role in the building seismic response. The large damages that occurred in precast RC buildings, during the recent earthquakes in southern Europe were mainly caused by the collapse of the cladding panels. Therefore, is required to revise, to revise the technological and design philosophy the panel-to-structure connection devices in RC precast structures. Starting from these considerations, the main topic of this thesis is the investigation of such connection devices. Deeply understanding the working principle of these systems makes it possible to open a way to solve the problem. The influence of the panels to the global response of precast structure is studied for different types of panel-to-structure connections (two types of hammer-head straps) and panels-to-foundation connections (fixed and rocking panels). Numerical models for the in-plane response of connection devices are developed using both existing experimental data from shaking table test performed by University of Ljubljana and result of new tests carried out at the Structures and Materials Testing Laboratory of University of Florence A new connection device, which better uncouples the in-plane seismic response, is developed and studied analytically and experimentally. The study highlights that traditional devices fail due to their limited in-plane displacement capacity while the new device has much better behaviour. The study showed that in-plane direction was critical for connection compared to the out-of-plane one. It also showed that fixed-base panels provide a better seismic performance of connection devices.

This thesis explores two hybrid systems employing a core material reinforced by an external skin, namely, cladding walls composed of polyurethane foam core sandwiched between fibre-reinforced polymer (FRP) skins, and beams composed of concrete-filled FRP or steel tubes. The walls were studied in two phases. In phase I, the polyurethane foam core was injected between two carbon-FRP (CFRP) skins. Ten panels were tested to investigate their structural performance and failure modes. Test parameters included quality control in terms of reproducibility of test results, moment-shear ratio, and the orientation of an architectural masonry-like coating. The study showed that design is governed by stiffness and not strength and that the CFRP was underutilized. Also, quality control was shown to be poor for this method of fabrication. As such, in phase II, ten panels were fabricated by laminating glass-FRP (GFRP) skins to prefabricated polyurethane foam blocks. Similar flexural testing was carried out to investigate two different densities of foam, and moment-shear ratio. The study showed evidence of high quality control and that the density of the foam core significantly affected flexural capacity and stiffness. Rectangular concrete-filled tubes (CFTs), with either steel or pultruded GFRP tubes were fabricated and tested as beams in three-point bending, at different shear span-to-depth (a/d) ratios of 1 to 5 to examine crack patterns, strength and failure modes. It was shown that the critical (a/d) ratio, at which moment capacity drops, is between 4 and 5 for CFTs with GFRP tubes and between 1 and 2 for CFTs with steel tubes. It was also shown that ductility is drastically reduced at (a/d) ratios below 3 for steel tubes. Crack pattern and size were highly dependent on the magnitude of slip between the concrete and tube. A major full depth flexural crack developed in all CFTs with GFRP tubes. However, when internal steel rebar was added, major diagonal cracks were formed in addition to fine flexural cracks.
