Abstract: Dembitsky A.O., Tytarenko R.Y. (head). Apartment building with an underground parking facility and commercial premises, designed within the village of Zymna Voda, Lviv Region. Master’s Qualification Thesis – Lviv Polytechnic National University, Lviv, 2025. Section 1. Architectural and Structural Solutions This section outlines the characteristics of the development site, presents the climatic parameters, key provisions of the master plan, and describes the spatial-planning, architectural, and structural features of the building. The technical and economic indicators provide essential information about the structure. Details on engineering and utility systems are presented, and tables specify the infill of openings as well as a detailed description of interior finishing materials. Structural System: 1. The load-bearing framework consists of a rigid monolithic reinforced concrete frame with columns and vertical stiffness elements ensuring spatial stability. 2. Foundation: monolithic slab, 600 mm thick, constructed of heavy concrete class C20/25. 3. External walls: solid ceramic brick with additional insulation using expanded polystyrene boards with a density of 60 kg/m?. Partitions are brick, 120 mm and 250 mm thick. 4. Columns: reinforced concrete, varying cross-sections according to design loads. 5. Floor slabs: monolithic reinforced concrete, 200 mm thick, flat slab type without beams. 6. Stair flights: cast-in-place reinforced concrete, supported on monolithic stairwell walls. 7. Roof: flat monolithic reinforced concrete, 200 mm thick, insulated with 200 mm extruded polystyrene boards according to the "Technonicol" system. 8. Windows and doors: PVC profiles, double-glazed units filled with argon. Section 2. Structural Analysis and Design This section presents the determination of building loads and the analysis of four main structural elements. 1. Floor slab (monolithic): modeled and analyzed in Dlubal RFEM. The slab is supported by columns, shear walls, and masonry elements; loads were applied according to consolidated combinations. 2. Reinforced concrete column: the most heavily loaded frame column was analyzed using results from RFEM. The calculation followed standard methods for reinforced concrete columns. 3. Monolithic stairs: stair flights and landings were analyzed as a continuous inclined beam. The calculated internal forces determined the required reinforcement. 4. Foundation slab: analyzed in RFEM considering all collected loads, including effects from other structural elements. Section 3. Technological and Organizational Solutions This section describes the construction site plan with all safety requirements, the technological procedure for constructing the monolithic slab, and the project schedule. Section 4. Economic Justification Local and consolidated cost estimates are presented, based on the technical and economic parameters of the building and results from previous sections. Section 5. Research Section The fire resistance of a typical floor slab was evaluated, considering the maximum permissible temperature of reinforcement according to European standards. Methods for increasing the fire resistance of the structure are also discussed. Keywords: monolithic slab, column, reinforcement, concrete, residential building, reinforced-concrete frame.
