Survey and assessment of the National museum building in Prague
Drdácký, Miloš ; Slížková, Zuzana
The report presents results of a complex survey of the health conditions and damages and failures of the building of the National museum in Prague. It further summarizes scientific investigations of the loads, namely of winds in situ as well as on models in a climatic wind tunnel where also soiling was tested. The results of material analyses and public attitude to soiling and failures on the façade are involved, too. The report has a rich photographic annex.
Zpráva o hodnotitelské misi do Regensburgu
Drdácký, Miloš
The report presents conclusions of an ICOMOS evaluation mission to Regensburg and Stadtamhof which are nominated for inscription on the list of World Heritage. The individual paragraphs deal with basic features of the nominated property, its boundaries and buffer zone, legislative protection, management and management plan, conservation, tourism, authenticity, cultural significance and other aspects, namely protection against flood and the attitude of citizens to cultural heritage. The last item was investigated using a questionnaire and its evaluation is shortly presented, too.
Non-destructive survey of the southern wall of the State castle of Křivoklát and opinion to its static consolidation
Drdácký, Miloš ; Lesák, Jaroslav
The report presents results of non-destructive investigations of a historic masonry wall using passive thermography and videoscopy. There are analysed defects and failures and evaluated suggested static measures aimed at consolidation of the masonry fortification wall and at an increased safety of foundations.
Structural assessment of a historic timber roof frame and barrel vault bearing a fresco by V.V. Reiner above the staircase in the Palace of Czernin
Drdácký, Miloš ; Frankl, Jiří
The report presents description and results of a survey of the state and defects and failures of a roof framework and a wooden barrel vault bearing a fresco by V.V.Rainer. Special attention is devoted to biological degradation and damages. There are suggested measures fro restoration.
Characteristics of an outdoor pavement mortar from the Karlštejn Castle and of its replacement by lime mortar with fibres
Drdácký, Miloš ; Slížková, Zuzana ; Zeman, Antonín ; Cikrle, P.
The report presents results of a complex survey and research of the state and characteristics of a historic outdoor pavement mortar from the fortification wall of the Karlštejn Castle. The results are compared to the characteristics of newly designed lime mortars with fibres.
Study of combined climatic influences and hydrophobization effects on sandstone pinnacles from the Santa Barbara church in Kutná Hora
Drdácký, Miloš ; Lesák, Jaroslav ; Slížková, Zuzana ; Pospíšil, Stanislav ; Delpech, P.
The report summarizes results of the first part experiments in the Jules Verne climatic wind tunnel CSTB in Nantes. It presents diagrams of temperature and moisture changes measured on both the exterior surface and inside historic sandstone pinnacles from the church of Santa Barbara in Kutná Hora at different combinations of climatic loads with changing temperature, rain and wind velocity characteristics. Thermography has been applied for surface temperature measurements. During the tests the hydrophobization effect was studied, too.
Parametrical study of the stress changes in the pelvis bone after hemiarthoplasty
Kytýř, Daniel ; Jírová, Jitka ; Micka, Michal
Article deals with development and utilization of parametrical FE model of pelvic bone for analysis of migration of implant head after hemiarthoplasty. The CE angle and direction of loading were taken as imput parameters for the stress analysis. The analysis was carried out as axially symmetric 2D contact problem. Extreme values of first principal stress, third principal stress and sum of displacements were used as a reference magnitude.
Experimentální studie-Vyloučení nadměrných vibrací kapalinovým tlumičem
Pirner, Miroš ; Urushadze, Shota
The new type of passive tuned liquid damper (TLD), which relies on the motion of liquid inside a movable rectangular tank with two degrees of freedom (horizontal displacement and rotation).The authors study the influence of vessel horizontal motion of and rotation on the damping of the vertical and horizontal vibrations of the footbridges.
Some properties applications of eigen functions of the Fokker-Planck operator
Náprstek, Jiří
Non-stationary solution of the Fokker-Planck(FP) equation leads to problem of eigen-values and eigen-functions of the FP operator. Problems of the asymptotic convergence related with stationary solution existence and the prospective metastability of the system are analysed.
Vaveletový rozklad nestacionárního náhodného signálu
Fischer, Cyril ; Náprstek, Jiří
The paper provides a support for the wavelet based approach for the analysis of the MDOF systems subjected to non-stationary excitation. It tries to cover the lack of input data in the form of the wavelet decomposition of seismic records.
