APPLICATION OF A METAL DOME IN A COTTAGE DURING THE DEVELOPMENT OF THE BALAKLAVA COAST OF THE BLACK SEA

Abstract

Development issues that remain relevant include determining the direction of development and development of the territory in the area of Vasilyeva Balka in the city of Balaklava in the presence of currently existing constants and variables. The territory development object is characterized by unique and potentially high consumer properties, provided that it is developed as a recreation center. Here it is necessary to pay attention to factors that contribute to the development of the territory, obstacles and neutral ones. Most hotels in Balaklava, as independent units, have a poorly developed infrastructure, a low level of customer service and an outdated number of rooms, which greatly reduces their level of competitiveness and attractiveness to consumers.

The location of the site of the recreation center "VASILI" in the mountainous and wooded part of the city of Balaklava involves the rational development of the site in the form of the construction of separate comfortable cottages. Comfortable cottages are designed in the form of buildings with a metal frame, and the second floor is made in the form of a mesh dome. The basis is the following design solution: the 1st floor is a post-and-beam system with plan dimensions of 8.8 m by 6.4 m, the second floor is a mesh dome with a diameter of 10.8 meters, a height of 5.4 meters with a ring balcony with an overhang of 1.5 m.

The research carried out made it possible to obtain a space-planning and constructive solution for the building that has an exclusive appearance and the possibility of significant glazing of the building, which is very original and preferable for the southern regions of the Crimean Peninsula

Subject: constructive solution for comfortable cottages.

Materials and methods: The existing design solution of a geodesic dome for long-span buildings was adopted as the starting material. To study the operation of dome elements as part of the frame of an individual cottage, a finite element model of the building was created using the LIRA SAPR program.

Results: the conducted research made it possible to obtain data for a comparative analysis on the rational consumption of metal for the elements of the frame and dome of the building.

Conclusions: the most effective sections are for the dome - a bent equal-flange channel with a section of 25x30x2 with a specific steel consumption of 1.22 kg/m, for the frame - a through-section column of spread channels connected by a lattice of a single angle with a section of 20x20x2 with a total specific steel consumption of 26, 28 kg/m.

Key words: cottage, dome, metal frame, finite element model.
