Stavebně-technický průzkum krovové konstrukce kostela sv. Františka Serafínského v Lipníku nad Bečvou
Hašová, Jiřina
The subject of this thesis was to make a constructive-technical research on timbers of St. Francis Seraph church in Lipník nad Bečvou. This church is registered into national list of sights as a sight number 29870/8-485. It is a Gothic-Renaissance building dating from 1590-1593. The roof above the cancel and nave consists of free floors dollar beams, queen post and truss frames. The aim was to reveal biotic damage to individual elements of timbers and to determine the extent of the damage. The evaluation of timbers was based on sensory and devices research. The roof was attacked mostly house longhorn beetle, rotting, especially in places where there was high humidity. The damage was caused mainly on wall beams and camping piece of tie beams. Based on achieved results we suggested remedial measures which are intended to preserve the built of wood, which is in a satisfactory condition. This thesis also deals with dendrochronological dating where we tried to determine the age of construction by dendrochronological analysis. The roof above the nave and chancel was dated to the period 1769-1771. Thesis is completed with anatomical determination of forest species which were used in individual parts of timbers. The results provide information for planned reconstruction of monument considering its current constructive - technical condition.

Dendrochronologické datování a stavebně technický průzkum roubené stavby v obci Písařov na Šumpersku
Piňos, Svatopluk
The bachelor thesis examines complete construction of the timbered building in the village Písařov in Šumperk region by building-technical research with using of non-destructive and semi-destructive methods and defining age of wood by using den-drochronological dating. The devices Ultrasonic timer, Resistograph 4453-D and new device, which is based on measurment of resistence during pushing jaws in drilled hole, were used to determinate building-technical condition.

Zaměření a stavebně-technický průzkum krovové konstrukce kostela Sv. Matouše v obci Postřelmov
Mičunda, Jan
This thesis assesses the state of the truss and steeple of the church of St. Matthew in Postřelmov. The main objectives are to draw the construction, conduct construction-technical survey and and date the construction using dendrochronology. The basic assessment consists in the analysis of the individual parts of the building and their typology. The drawing part of the thesis focuses on the truss, including the steeple. The objectives of the construction-technical evaluation are to assess the structural protection, to locate, identify and detect biological pest infestation; the dendrochronological dating will try to determine the exact year of construction and dates of potential repairs. According to the results, remedial measures will be proposed designed to maintain wood elements in a satisfactory condition.

Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela sv. Václava v obci Přísnotice (okres Brno-venkov)
Malachta, Radovan
Aim of the study was focused on dendro-chronological dating of historical and architectural evaluation of the roof truss of the St. Wenceslas church in the village Přísnotice. Dendro-chronological dating documented the start of construction of the truss and the subsequent repairs. Identified dates were compared with historical data derived from the available historical sources and Internet resources. Dendro-chronological dating of woody species was preceded by the determination of samples by microscopic and macroscopic signs of wood. In the structural-historical exploration part, my work was focused on the wooden structures and their development. Results of dating and structural-historical survey specified the development of the truss construction in the St. Wenceslas church in the village Přísnotice.

Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela sv. Jana Křtitele v Hlučíně
Rataj, Tomáš
The aim of this thesis was to conduct a survey and documentation of construction and the historical development of Object church. John the Baptist in Hlučín, district Opava. The available resources and literature to chart the history of truss structure and determine its typology. Anatomically determine tree species in different parts of the roof structure of the church and using dendrochronological analysis to determine the age of the samples. The work deals with a methodical procedure from dendrochronological sampling, treatment and subsequent measurement until after dating results with comparison using statistical methods within specified Czech and Moravian standard chronologies of tree species. The work is complemented by the resources available on the historical development of building construction. As a result, based on microscopic slides of the samples was identified fir wood. There have been a historical summary of the aspects related to the construction and definition of the age of the individual parts of the roof structure. The truss nave was dated to 1890, the age of the truss presbytery was designed in 1732. Truss above the nave was defined as longitudinally coupled rafter construction Hambálková, stagnant faeces. Historical evaluation of extended documentation package, which is now the object of the church we can leave to future generations. Dating age truss church confirmed the historical development of the subject and contributed to the overall mapping of the now almost restored monument.

Dendrochronology of representative autochtonnous tree species on environmental and temporal gradients
ČEJKOVÁ, Alžběta
This thesis is focused on application methods of dendrochronology on various ecological and historical aspects of forest communities, human management practices, and historical utilization of wood. Studies revealed growth responses of trees in various type of forest vegetation represented by spruce forest, alder carr and alluvial forests and involved autochthonous tree species with all morphological types of wood. These works demonstrated necessity of dynamic evolving of the regional chronologies for the Czech Republic.
