This work is focused on compilation of general diagnostic methods used for diagnostic of wooden structures specifically listed wooden roof truss of church st. Bartholomew in Ivan. The main impulse of diagnosis was extensive damage and attack of truss and effort on rehabilitation and construction of the entire building of the church with an emphasis on preserving historical values. Diagnosis of truss was based on the research used sense and instrumental methods. In the first step, identify all dimensions of the individual elements of the structure was determined, the type truss system was intended. Follow-up survey was focused on determining the extent and causes of damage. In design of the rehabilitation process emphasis is placed on structural rehabilitation provided by follow-up processes, such as preventive chemical protection.

The content of this work was to carry out construction-technical survey of timber structures of the existing building in order to design an appropriate procedure for their reconstruction. The survey showed construction in an unsatisfactory to disrepair, so further work also includes the static calculation of new structures proposed instead of the current. Timber structure in the building has form of staircase, roof and ceiling construction. Newly designed the following types of stairs and roof trusses from which the lower belts are used as ceiling beams. The new proposal also includes possible roofing, roofing options, developed one of them. The work also includes drawings, bill of materials and cost estimate staircase structure and truss. Specialization in the field of civil engineering is represented by drawings of the new truss and passport (view of current state) whole object on parcel ST.74 / 1, land Tišnov (okr.Brno-venkov), the content of which was the basis for this work.

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.

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.
