Zastřešení víceúčelového sportovního objektu / The Roof Structure of a Multipurpose Sport Building

Malchárek, Robert January 2017 (has links)
The subject of the Diploma thesis is a design wooden structures of a multipurpose sport building in Šumperk. The floor plan measurements of the building are 45,0 x 48,0 m with the maximum height 15,0 m. The solution is choosen on the basis of two variants. The structures is designed with respect to ultimate and serviceability limit states. The multipurpose sport building is consist of 13 main truss centre to centre spacing 4,0m. The main structural system is design as the three-hinged arched structure made of solid timber and in the second variant as the arched structure made of glue laminated timber. The spatial rigidity of the structure is secured of diagonal bracing. The roofing is carried by rafter which are safed by purlin and then by upper chord. The steel columns are design as a part of gable wall. The project was carried out in the scia Engineer 2014 software. Some of the particular elements both variants were checked and designed by manualy calculating. The thesis includes structural design report, joints structures, drawings and production drawing the element of the three-hinged arched structure.

Horský hotel ve Velkých Losinách / Mountain hotel in Velké Losiny

Kašíková, Anna January 2022 (has links)
The work deals with the design of a load-bearing wooden structure of a mountain hotel in the foothills of the Jeseníky Mountains. It is a building without cellar, two floors and a attic room. The floor plan of the building is 17 x 30 m with a porch of 3 x 10 m. Height of the building up to the ridge is 13.2 m. The design of the roof structure has been chosen from 2 different variants. Material usage consist of grown wood of class C24, glued laminated wood of class GL32h and steel S355. Static analysis was calculated by Dlubal RFEM software.

Horský hotel v Králíkách / Mountain hotel in Králíky

Hoffmannová, Zdislava Unknown Date (has links)
The subject of this thesis was a structural design of a timber structure of a mountain hotel in Králíky. The object was a three storey building in a shape of letter U. The project was made in two different variations. The first one consisted of timber frame system with walls securing spacial stability. Computational model was created as a spacial bar 3D model in SCIA Engineer 19.1. The internal forces were calculated using the linear static analysis. The loadbearing structure was designed according to ultimate and serviceability limit states in SCIA Engineer 19.1. The thesis includes joints and anchorage design according to valid standards. Glue laminated timber was chosen as a material for the loadbearing structure while solid timber was chosen for wall structures. The second variation was made out of cross laminated panels. Wall panels were calculated by hand calculation whereas floor and roof panels were calculated using Agrop Nova Element software. Spatial model was made in SCIA Engineer 19.1 software to design joints and for global deformation check as well. The thesis includes engineering report, structural design report as well as drawings.

Experimentální výzkum v oblasti lepených lamelových prvků na bázi listnatých klimatolerantních dřevin / Experimental Research in the Field of Glue Laminated Elements on the Basis of Climate Tolerant Deciduous Trees

Šuhajdová, Eva Unknown Date (has links)
This Doctoral thesis is focused on research of usability hardwood that is not used in structural engineering nowadays. Analysis of known hardwood properties and its verification by experiment was made. Mathematic analysis using the PROMETHEE method was used for most suitable hardwood species selection in the Central Europe conditions. The most suitable hardwood – beech – was subjected for further tests: finger-joint load bearing capacity experiment and beech homogenous and hybrid glulam experiment. The test results are compared with the values from professional literature.

Development of preservative-treated cross-laminated timber and lignin-reinforced polyurethane-adhesive for glued laminated timber

Ayanleye, Samuel Oluwafemi 08 August 2023 (has links) (PDF)
Interest in the use of mass timber in building and construction is growing worldwide, this is due to the structural integrity and reduced environmental footprint of timber-based structures. Concerns associated with the biological and environmental degradation of mass timber necessitate the development of adequate protection strategies to ensure the durability of these products. Preservative treatment is a proven technique that increases the durability and performance of wood in-service and can also be applied to large-sized timber panels such as cross-laminated timber (CLT). Therefore, this study focused on investigating the feasibility of treating prefabricated 3- and 5-layer CLT panels with Copper-azole type C (CA-C) and micronized copper azole (MCA) preservatives. Further, we studied the effects of panel layup and thickness on the preservative impregnation in CLT. Based on the experimental results, we found adequate preservative penetration and retention in the treated 3- and 5-layer CLT panels, particularly in CA-C treated panels. Also, the lengthwise layup shows better treatment results in both CA-C and MCA-treated panels. In addition to the preservative-treatment of CLT panels, this dissertation covers the development of lignin-reinforced polyurethane adhesive (PUR) for bonding glue-laminated timber (Glulam). Herein, the glulam were fabricated and bonded using lignin-reinforced PUR at different wt% (1, 2, and 3) and tested for shear strength, wood failure and delamination. The lignin-treated PUR samples showed improved adhesion properties via high shear strength and reduced delamination compared to the control specimens. Thus, the lignin-reinforced PUR adhesive shows great potential as a bio-based and environment-friendly wood adhesive for producing glulam used in structural applications.

Sikorová, Radka January 2018 (has links)
The aim of this master thesis is to design and check a bearing structure of The multifunctional center in Jihlava. A bulding is partly ground flooring. The structure follows an L-curve in a plan with the biggest axial lenght of 40 m. A roofing is in a shed shape and the pitch of the roof is 5,73°. The highest point of the bearnig structure is 11,5 m. The structure has various frame systems, which is a truss, a gross-cross section beam with an inner column in the middle of a span and a gross-cross section beam without an inner column. The structure is designed mainly from timber members, a glulam and solid timber. A steel part of structure consists of the metal fasteners and rods.

Zastřešení sportovního objektu / The Roofing of the Sport Hall

Stehlíková, Iveta January 2019 (has links)
The goal of this diploma thesis is designed and reviewed the roof of the timber construction of sports structure, the span is 50 m and the length is 90 m. The design of the structure is located in Ústí nad Orlicí. The shape of the hall is arc sector. The structure is designed from glue laminated timber, solid timber and steel load bearing elements. The main load bearing elements are truss girders, which static function as two hinged arch. The stability of the girders is ensured by purlins, transverse stiffeners and longitudinal stiffeners. The stiffeners are situated in five fields. Front sides are made by girts and truss columns.
