Description
  • Considerably different approach to the analysis of masonry structures is offered through the application of multi-scale analysis combined with periodic homogenization exploiting the concept of periodic unit cell. In such a case the true geometry of the masonry structure can be reflected even for structures with irregular arrangement of bricks or stone blocks in case of quarry masonry. Such an approach requires the knowledge of material properties including fracture energies and interfacial properties, of individual phases - bricks and mortar. Determination of these properties from carefully prepared laboratory tests is thus the main goal of this contribution. A special attention is paid to the determination of fracture energy of individual constituents. Apart from that, a set of large scale specimens is tested to provide macroscopic response used in turn for comparison with numerical simulation based on first order homogenization.

  • Značně odlišný přístup analýzy zděných konstrukcí je nabízen prostřednictvím víceúrovňového modelování, homogenizační techniky a konceptu jednotkové periodické buňky. V tomto případě geometrické uspořádání zdících prvků v konstrukci může být zohledněno i pro neperiodické zdivo z lomového kamene. Tento přístup vyžaduje znalost takových materiálových charakteristik, jako jsou např. lomová energie cihel a malty a smykové parametry spáry. Stanovení těchto charakteristik z pečlivě připravených laboratorních experimentů je těžištěm této práce. Zvláštní pozornost se klade na odvození lomové energie obou fází zdiva. Stranou odvození mezoskopických materiálových charakteristik byla zkoušena skupina dvanácti makroskopických těles z důvodu následného porovnání s numerickými simulacemi. (cs)
