The wooden structure of the building for a kindergarten
Dreslerová, Natálie ; Pešek, Ondřej (referee) ; Bukovská, Pavla (advisor)
The subject of the bachelor thesis is a design of a timber structure for living rooms of a kindergarden in the village of Vlkov near Velká Bíteš, and a creation of a 3D model using the BIM method. The entire building has only one above-ground floor and consists of two structural parts. The first part is mainly designed from masonry and reinforced concrete elements. The second part is an annex consisting of two identical „wings“ with structural elements made of glued laminated timber. The supporting system consists of transverse frames formed by beams and columns, which are then supplemented with purlins that transfer the load of the roof and with stiffening elements in the form of steel tie rods. The timber extensions are covered with a mono pitched roof with a slope of about 5°. The static model and determination of internal forces were ensured by the Scia Engineer 22.0 calculation program. The assessment of individual elements themselves was done manualy using Microsoft Excel. Connections are solved using steel connecting elements that were selected and verified by manual calculation. A significant part of the work was based on cooperation with colleagues from the Institute of civil engineering and from the Institut of concrete and masonry structures.

Seismic performance of timber frames
Pospíšil, Stanislav ; Urushadze, Shota ; Koleš, Jan
A series of dynamic experiments was performed on one-story timber frame. In comparison with the previous frames [1, 2], improved connection between column and girder was used here. The tests included sinusoidal sweeps in two directions, arbitrary signals simulation earthquake loads in three directions, and snapback tests. Various parameters were measured, for example tension on columns and slabs, rotation between columns and beams, displacement of columns and acceleration of columns and beams. All these parameters lead to classification of the frame behavior with designed type of connection, for example the natural frequencies, eigenmodes and other dynamical properties of the structure. Parameter description will allow us to design and improve mathematical model of the timber frame.

Advanced detection methods used for on-site inspections of historic timber structures
Bláha, Jiří ; Drdácký, Miloš ; Kloiber, Michal
Research and evaluation of timber structures used within historic buildings should have consideration for an authentic substance bearing the most of specific heritage values. Modern technologies have brought new tools for a detection of the subsurface biogradation. Among the non-invasive techniques the ultrasonic testing, portable X-ray scanning and thermo-vision belong to most promising ones. There are also sophisticated semidestructive methods like microdrilling or video scope available.
