Drdácký, Miloš ; Jirovský, Ivo ; Mlázovský, V. ; Růžička, P. ; Wald, F. ; Kirizsán, I. ; Szabó, B.
Poster presents knowledge acquired at experimental carpentry in combination with scientific research into behaviour of traditional carpentry joints. Results of tests on replicas as well as authentic joints are used for calibration of computational models and further for structural analysis of historic development of roof timber frames.
Experimental research of steel bolted joints under repeated loading
Gregor, D. ; Wald, F. ; Jirovský, Ivo ; Drdácký, Miloš
The paper describes experiments on beam to column connections subjected to cyclic loading. There are presented measured changes in tension state of bolts and typical plastic failure mechanisms of the joint plate.

Report summarizes results of NDT survey of masonry and timber structures of the Church Tower of the Karlštejn Castle. The applied methods involve passive thermography for masonry, X-ray, core drilling, resistance micro drilling and visual assessment for timber.
Experimental methods for study of historical structures
Drdácký, Miloš ; Jirovský, Ivo ; Lesák, Jaroslav ; Pospíšil, Stanislav ; Slížková, Zuzana ; Valach, Jaroslav ; Vavřík, Daniel
The paper presents a review of selected experimental methods for study of historic materials and structures, which have been developed or applied in the Institute of Theoretical and Applied Mechanics of the Academy of Sciences of the Czech Republic in Prague. It discusses peculiarities of the experimental investigation of historic structures and materials, which influence basic methodological approach. The contribution is focused especially on nonstandard methods of study of material characteristics and on testing of historic structures subjected to environmental loads or actions.
