Stressed-strain state of structural elements of buildings by 3d-printing technology

The results of surveys on development in the near future indicate that Ukraine has great prospects for low-rise construction. But low-rise construction can be economically justified when the cost of the land is minimal, or construction period is reduced to the maximum. Such a solution is construction using 3D-printing. This article provides examples of 3D-printing technology application in various industries, namely in construction; features of 3D-printers and their capabilities; investigations of the stress-strain state of an external load-bearing wall fragment and a two-storey residential building, constructed with 3D-printing technology. Purpose. Development of a method for calculating building envelopes and low-rise residential buildings in general, constructed with 3D-printing technology. Methods. Research of the stress-strain state of building structures produced by means of 3D-printing technology was carried out using “LIRA − CAD 2013” software package. Results. Based on the calculations of the external wall fragment and a two-storey residential building, produced by 3D-printing technology, places where maximum stresses and displacements occur were identified. it was also found out that they do not exceed boundary values. Scientific novelty. For the first time, the basic guidelines for the calculation, design and installation technology of structures of low-rise residential buildings using 3D-construction printing technology are proposed taking into account the absence of a regulatory framework for this type of work. Practical value. The studies conducted allow us to manufacture individual building structures and low-rise buildings using 3D-printing technology.
