Projektna rešitev detajla stika medetažne plošče z monolitnim opečnim zidom : diplomska naloga

Felc, Aleksander (author), Bosiljkov, Vlatko (mentor), Antolinc, David (co-mentor)

Diplomska naloga obravnava detajl stika med zunanjim monolitnim opečnim zidom in medetažno armiranobetonsko ploščo na primeru enodružinske hiše v Beltincih. Zid je izdelan iz brušenih opečnih zidakov polnjenih z mineralno volno. Tak zid ima dobre termične lastnosti in ne potrebuje dodatne toplotne izolacije. Klasična izvedba stika, kjer je naležna dolžina plošče enaka debelini zidu ni primerna, saj odsotonost dodatne zunanje izolacije privede do pojava toplotnega mostu. V diplomski nalogi je predstavljena energijska optimizacija stika, ki se doseže z zmanjšanjem naležne dolžine plošče. Pri določitvi detajla sta uporabljena kriterija za preprečitev nastanka kondenzacije in nevarnosti pojava mikroorganizmov ter omejitev faktorja toplotnih mostov. V drugem delu naloge je predstavljena numerična analiza odpornosti stika na vertikalno obtežbo, ki je bila izvedena v programu SAP2000. Rezultati analize so pokazali, da zasnovani stik uspešno prenese projektno obtežbo.

• Title: Design solution of a wall-slab connection detail for masonry building : Graduation thesis

Abstract

This thesis deals with the wall-slab connection detail in monolithic masonry buildings. It is presented on the case of a two storey building located in Beltinci. The masonry wall is made of hollow clay blocks filled with mineral wool insulation. This type of masonry has good energy efficiency and does not need additional thermal insulation. In usual masonry constructions the support length of a reinforced concrete slab is equal to the wall thickness which leads to appearance of a thermal bridge. This thesis presents thermal optimization of the wall-slab-junction which is achieved by reducing the bearing length of the slab. The criteria for determining connection detail is based on prevention of the condensation and mold growth on inner surface of the wall and by limiting the value of the linear thermal bridge coefficient. In the second part of the thesis the load-bearing capacity of the vertically loaded wall is checked using a numerical finite element model that was prepared in the program SAP2000. The results of the numerical analysis show that the proposed connection detail adequately sustain applied loads.
