Abstract
The use of thin brick veneer layers for building facades becomes more popular nowadays. Using thin bricks (50−65 mm thick) instead of normal 100−120 mm thick bricks let us to save expenses up to 50% related to materials. The connection of thin veneer layer with inner construction wall must be assured. Usually, the connection is fulfilled using flexible metal or composite ties. The main issue for this connection is tie pull out strength from thin brick masonry. This strength depends on type and construction of ties and it governs the number of ties need for facades. This article describes experimental research of pull out strength of flexible steel ties in thin brick masonry. Two possible anchoring types were used. Experimental test results and analysis are described in the article.
Highlights
When building new buildings with layered exterior walls or renovating them, one of the most rational solutions is an establishment of ventilated facade
In comparison of the results of samples with different bricks and the same anchoring methods, it can be said that anchoring strength of the samples with perforated bricks is higher up to 54%
The greater anchoring strength of the ties was observed in samples with perforated bricks
Summary
When building new buildings with layered exterior walls or renovating them, one of the most rational solutions is an establishment of ventilated facade. The flexible ties are placed in the horizontal mortar joint of the masonry veneer layer, leaving a distance of about 30 mm from the outer surface of the layer. In this case, the load bearing capacity of the flexible tie depends on the tie pull out strength from mortar joint. The load bearing capacity of the flexible ties which depends on anchoring of the tie in bed joint is determined by the experiments. The samples were tested with short-term static load by pulling out the tie from masonry bed joint. Experimental investigation of pull out strength of flexible ties in thin brick veneer layer
