FEATURES OF DESIGN AND CALCULATIONS OF COMPLEX REINFORCED CONCRETE FRAMES OF BUILDINGS

The article considers and systematizes the load-bearing structural systems of buildings with complex space-planning configurations, taking into account design solutions, structural loading and stress states. The features of the perception of loads and their rational distribution between the structural elements of frame buildings with complex space-planning solutions are analyzed. The main structural schemes of complex frames, schemes of their deformations and plots of moments under the influence of vertical and horizontal loads are introduced. The paper reflects the modern practice of preliminary approximate calculations of the approximate dimensions of the sections of frame structures of frame buildings for the possibility of further collecting loads and performing refined calculations using modern calculation software systems. The proposed method for modeling the nature of the work of complex frames of frame buildings and coordinating their space-planning, design and calculation systems will be useful for researchers, architects and design engineers during the design of new types of buildings, taking into account their operation under emergency conditions.
