Investigation of The Effect of Knitting Row on Vibration Structure for A Wide Chimney Made With Brick Bar

Abstract

Building systems have unique structural behaviour. In addition to the obvious material properties used in the formation of this behaviour, the geometric shape is also of great importance. In this study, the mechanical effects on the chimney-shaped structure built with bar bricks for product storage were investigated under compression and vibration conditions. Finite element analysis was used as a research method. Solid bar bricks and cement with standard specifications were used as the intermediate filling material for the construction system, which was formed in a wide circular array and short knitting height. Considering the ideal behaviour of the materials, a fully elastic solution was made. As a result of the examination, the effect of the knitting order on the natural frequency was found to be low, as the reason for this, it was seen that the geometric structure exhibited a very tough behaviour against deformation. The stress concentration was observed at the fillings between the bricks laid in the same layer. The dimensionless deformation at natural frequencies was 1.4 times the diameter of the chimney. The knitting order affected stress values and symmetrical distribution formed in the brick. The results were discussed over the findings.
