Tillämpning av Posi-Joist i större byggnader

Bonde, Albin, Karlsson, Viktor January 2023 (has links)
For a long time, frames have been built with traditional materials such as concrete and wood but there are newer, less tested alternatives. Posi-Joist is a new kind of hybrid beam which means that it consists of different materials that work together to form a stronger frame. Posi is a collective name for the different parts of the beam. Because Posi-Joist is a new beam, it hasn’t been tested as much as the more traditional materials. The purpose of this report is to investigate if Posi-Joist is an acceptable frame to use on larger constructions since it hasn't been investigated before. In order to investigate this, a hybrid frame consisting of Posi-Joist beams will be compared to a concrete and a wooden frame. When choosing a material there are different parameters that matter. The different materials will demand different spans, have different environmental impact, and have different costs. To investigate which frame is the optimal choice, different software will be used. Autodesk Revit will primarily be used to draw the frames’ different designs. Frame Analysis and FEM-Design will be used to perform calculations on the strength of the frames. One Click LCA will be used to obtain LCC and LCA. The wooden frame was the most expensive since the concrete frame’s price was just 40 % of the wooden frame's total cost. The hybrid frame’s price was 52,4 % of the wooden frame’s price and was therefore more expensive than the concrete frame but cheaper than the wooden frame. The wooden frame had less environmental impact since it emits 11,2 % of the concrete frame’s emissions. The hybrid frame emits 90 % of the concrete’s total emissions. The hybrid frame can manage the largest spans. The conclusion is that the concrete frame is the best option when it comes to design and price but has the most environmental impact. The wooden frame had the least environmental impact but could not manage compatible spans. The hybrid frame could manage the largest spans but was neither the worst nor the best in any of the other categories.

Centrum umění a řemesla / Arts and crafts centre

Kadubcová, Denisa January 2018 (has links)
This Master’s Thesis deals with a design of a detached Leisure center. The building is situated on a specific plot of cadastral area of Brno city, more precisely in Útěchov u Brna. The aim was to create an object suitable by its disposition solution for requirements of leisure center for children and adults. The building is designed as basementless, with two above-ground floors topped by flat roof. Wooden frame system with inserted thermal insulation and ETICS system in case of peripheral walls was proposed for load-bearing walls. Load-bearing structure of ceiling and roof is made by wooden-steel Posi-joist beams. The work also includes fire safety and thermo-technical assessment.

Komunitní centrum Petrovice / Petrovice Community Center

Flašková, Veronika January 2020 (has links)
The subject of diploma project is the design of complex of buildings using hemp lime composite, in English known as Hempcerete. Four detached houses are completed by building of facilities. Buildings have one to three floors. The composite fiercly reduces carbon footprint in building industry. The design is focused on different construction systems using hemp lime composite as a wall filling. Detached houses are made of load bearing timber frame with cast-in-situ hempcrete, building of facilities is made of reinforced concrete with precasted blocks. All buildings are cellarless. Detached houses are shed roofed, building of facilities is gable roofed.
