[pt] O presente trabalho, desdobramento da pesquisa desenvolvida entre 2007 e 2009, relatada na dissertação de mestrado intitulada Design de estruturas reticuladas de bambu geradas a partir de superfícies mínimas, tem como objetivo principal a aplicação de alguns dos modelos de estruturas de cobertura desenvolvidos pelo LILD (Laboratório de Investigação em Livre Desenho), em escala e contexto real para uso comunitário. Isso ocorre através do ensino de técnicas simples e de baixo impacto ambiental, em processos de construção coletiva utilizando materiais e mão de obra locais. Por meio da elaboração de desenhos, modelos físicos reduzidos e da prática construtiva coletiva em si, obtém-se uma dinâmica de troca de saberes entre mestres e aprendizes, onde o conhecimento flui de maneira multidirecional, se retroalimenta. O aprendizado obtido fica evidente em dois momentos: no desenvolvimento das estruturas em laboratório, pois ampliam o repertório de unidades estruturais do LILD, e na construção das mesmas fora dos muros da universidade, pois trazem resultados reais tanto sobre os saberes trocados entre os envolvidos quanto à ação do meio físico e social sobre o experimento. / [en] The present work, unfolding of the research developed between 2007 and 2009, reported in the master dissertation entitled Design of bamboo frame structures generated from minimal surfaces, has as main objective the implementation of models of roof structures developed by LILD (Laboratory Research in Free Design) on a scale and real context for community use. It happens by teaching simple and low environmental impact techniques in processes of collective construction using local materials and labor. Through the development of drawings, reduced physical models and collective constructive practice itself, we can get a dynamic exchange of knowledge between teachers and learners in which knowledge flows multidirectional way, feeds itself. The knowledge gained is evident in two phases: in the development of structures in the laboratory, it expands the repertoire of structural units of the LILD, and building them outside the walls of the university, because they bring real results both on the knowledge exchanged between those involved as the action of the physical and social environment on them.

In der aktuellen Baupraxis werden mit Standard-Tragelementen meist rechteckige Grundrisse erzeugt. Ausgenommen sind weitspannende Konstruktionen, wie Kuppeln von Domen oder Kühltürme von Kraftwerken. Im Gegensatz dazu waren Schalen aus Stahlbeton im Hochbau im vergangenen Jahrhundert weit verbreitet. Dazu wurden in der Regel große Strukturen in situ betoniert. Zusätzlich wurden weit spannende Fertigteile mit relativ geringer Breite hergestellt. Diese Faltwerke oder doppelt gekrümmten Elemente wurden zum Teil mit einer Dicke von weniger als 10 cm realisiert und häuf g im sofortigen Verbund vorgespannt. Bedenken hinsichtlich der Korrosionsbeständigkeit können ein Grund dafür gewesen sein, dass solche Konstruktionen heute üblicherweise nicht mehr gebaut werden. [Aus. Einleitung] / In current building practice, standard load-bearing elements are mostly of rectangular shape. Exceptions are large shell structures, such as cupolas of domes or cooling towers of power plants. In contrast, shells made of reinforced concrete (RC were widely applied for building construction in the last century. For this purpose, large structures were usually cast in situ. Additionally, long-span precast elements with limited width were produced. These folded plate or doubly curved elements were realised with a thickness of less than 10 cm and usually prestressed with steel tendons. Concerns regarding the corrosion resistance might have been a reason that such constructions are not build regularly today. [Off: Introduction]

During an inventory of Ör church’s roof structure in 2021, it was discovered that the roofstructure above the church’s nave contains a large amount of reused structural parts froman earlier roof structure. The reused structural parts are most likely originated from Örchurch’s early medieval roof structure.This thesis is an attempt to reconstruct the early medieval roof structure with the use of3D-laser scanning. The goal is to present a possible shape and 3D-model of the earlymedieval roof structure. The existing roof structure will also be documented. One aim ofthe thesis is to develop and evaluate the method of using 3D-laser scanning for thispurpose.The reconstruction resulted in eight different shapes and 3D-models of the early medievalroof structure. The documentation of the existing roof structure above the nave resulted inupdated section, plan and detailed drawings.The method of using 3D-laser scanning gave a detailed point cloud of the existing roofstructure. The point cloud had low density points in certain parts of the roof structurewhich is a consequence from the implementation of the 3D laser scanning. For thismethod a field study and planning in advance is recommended for best possible result.

Diploma thesis Pension - riding school is processed in the form of project documentation containing all requirements according to applicable regulations. The proposed facility is located on a parcel file with parc. no. 583/1, 584/1 and 16/1, in the village Vávrovice, which falls under the statutory town of Opava. It is a new basement house, which belongs to the civil, specifically in OB3 terms of fire safety. The building has a cross shape with a central raised portion compared with the lateral sides. The central part has 3 floors and the ground, which can later be used as an attic, two side sections have only 1.NP and attic. The shape of the roof ridge. The building is made of aerated concrete blocks YTONG and fully insulated.

The thesis is focused on the assessment of two wooden roof structures of the building, which is located in Brno on the street Rumiště 8. Parts of the work are also theoretical knowledge of roof structures, building technical survey and diagnostic methods. Rating roof truss was based on a survey of sensory and instrumental methods. In the first step were measured dimensions of roof truss members and were determined roof structures. In the next section was researched damage of elements and his causes. Rehabilitation solution was established for each type of damage to the components resist any attack as long as possible. This report had been prepared for the property owner who plans complete reconstruction.
