The constructive solution for coupling a large-span steel coating with a bearing system made of monolithic reinforced concrete of the “Atomic energy” pavilion of JSC “VDNH”

Abstract

Introduction. The increasing use of a variety of modern architectural forms of public buildings of mass use entails the search for appropriate design solutions that should ensure safety, serviceability, as well as the durability of load-bearing structural systems and their elements.Aim. Using the example of the designed and already under construction exhibition pavilion “Atomic Energy” on the territory of JSC “VDNH”, one of the possible solutions for the coupling of large-span roof system with a structural system of monolithic reinforced concrete is shown.This coupling option includes the supporting parts of the steel cantilever trusses of the roof embedded in monolithic pylons and bracing members. The calculations and detailing carried out showed that the new coupling solution meets the requirements of the current standards for load-bearing capacity, rigidity and crack resistance.Materials and methods. By means of numerical modeling using various computational complexes, analysis of experimental data of full-scale models and their comparison with modeling data, the initial data for the construction of the main load-bearing structures were obtained.Results. As a result of the applied integrated approach, the initial data for the construction of the main loadbearing structures with atypical cross-sectional parameters were obtained and verified.Conclusions. During the design of the load-bearing frame, the system of coupling of large-span steel trusses of the cantilever type with monolithic reinforced concrete structures of the “Atomic Energy” pavilion on the territory of JSC “VDNH” was improved.
