Abstract

V diplomski nalogi sem predstavil različne tipe kamnitih zidov in njihovo izdelavo. Predstavljeno je tudi kamnoseško orodje in vrste obdelanega kamna. Kamen je najstarejši gradbeni material za zidane konstrukcije. Iz njegove uporabe izhajajo vsa znanja o zidarskih tehnikah in zvezah. Glavni namen preiskav je ugotoviti, ali lahko zidarska zveza vpliva na tlačno trdnost kamnitega zidu. V ta namen smo zgradili troslojne kamnite zidove z dvema različnima zidarskima zvezama. Prvo polovico zidov smo pozidali z vezniško zidarsko zvezo, drugo polovico pa s smerniško zidarsko zvezo. Zidovi so bili pozidani z apneno malto, nato pa ometani z grobim in finim ometom. Opisane so preiskave za določanje tlačne in upogibne trdnosti za apneno malto in kamen. Opravili smo tudi preiskavi trdnosti stika med kamnom in malto ter trdnosti jedra zidu. Pri tlačni preiskavi zidov smo s globalne deformacije zidu. Teste smo opravili na dveh nizkih in dveh visokih zidovih, tako da smo lahko analizirali tudi vpliv višine preskušancev na tlačno trdnost zidovine. Ugotovili smo, da zidarska zveza ne vpliva na tlačno trdnost zidu, kar velja tako pri nizkih kot pri visokih zidovih. Tlačna trdnost visokih zidov je nekoliko nižja od tlačne trdnosti nizkih zidov. V nalogi sem naredil pregled modelov za izračun tlačne trdnosti ter analiziral različne pristope k izračunu tlačne trdnosti enoslojne in večslojne zidovine. ter jih s primerjal z eksperimentalnimi rezultati. Izkaže se, da je ob kombinaciji Mann-ovega in Bindinega modela možno napovedati tlačno trdnost večslojne kamnite zidovine

Secondary title: Compressive tests of multiply-leaf stone masonry walls
Secondary abstract: In the thesis overview of different types of stone masonry and the construction techniques are presented. There are also presented stonecutting tools and different types of stone masonry units in dependence from the extend of dressing. Stone is the oldest building material for building masonry structures. Thus all the masonry techniques developed from the history of building with stone. The main purpose of the investigation was to determine the influence of masonry bond on the compressive strength of stone masonry. For this purpose three-leaf stone masonry walls with two types of masonry bond were built. The first type was built with through stones connecting outer leaves through the thickness of the wall. The second one was built without through stones but with staggering units along the edges. All the specimens were built with lime mortar and than plastered with coarse and fine plaster at the end. Results of determing compressive and flexural strength of mortar and stone and their bond are also presented. Inner core was also tested and its compressive and splitting tensile strength were determined. During compressive tests of masonry global deformations were measured. Compressive tests on masonry were performed on the specimens of the size of wallette and wall. The results of tests revealed that masonry bond do not have significant influence on obtained compressive strengths. Compressive strength was slightly lower for walls in comparisson to wallettes. Summarizing all experimental data and different analitical models for predicting compressive strength of multipleleaf masonry walls, it was showen that Mann's and Binda's models can be used for estimation of compressive strength for multiply-leaf masonry
