Description	Vyztužené a předpjaté zděné konstrukce jsou obvykle navrhovány pouze na základě zkušeností projektanta. Přesné metody a vztahy odvozené z laboratorních experimentů nebo numerických modelů v širším měřítku prakticky neexistují. Předpínání či spínání zdiva přitom patří mezi velmi efektivní způsoby oprav objektů, které jsou silně poškozené. Vliv předpětí je totiž okamžitý. Pro širší a jednodušší využití předpínání je potřeba vytvořit přesnější pravidla a postupy. Tento příspěvek je zaměřen na analýzu dodatečně předpínaného zdiva prováděnou s využitím metody konečných prvků a 3D modelů. Numerické modelování by mělo umožnit lépe poznat a popsat chování předpjatého zdiva, které by tedy bylo následně srozumitelnější pro běžné projektanty a statiky. (cs) Reinforced and post-tensioned masonry structures are usually proceeded according to project engineers' experience. Exact methods and formulas derived from laboratory experiments or numerical models do not exist in general. Post-tensioning of masonry ranks among very effective ways of repairs of buildings that are highly defective. The influence of prestress is immediate. For wider and simpler application of post-tensioning, more precise rules and figures are needed. This contribution is focused on analysis of reinforced and post-tensioned masonry structures using the FEM methods and 3D models. Numerical calculations should analysed the behaviour of prestressed masonry so this could be more apprehensible for designers and engineers. Later the calculations will be compared to results of experimental measuring of samples. The leading aim of the project is to deduce the conclusions and recommendations for practical use that follow on masonry analysis.
