Steel space frame structures of long-span buildings

Abstract

In the modern world of digital technologies, the goal of architectural and structural design is to organize a safe and comfortable environment for human life. Globalization leads to buildings becoming increasingly spacious and having more capacity. As the complexity of construction structures increases, they become more vulnerable to external natural and man-made disasters. Consequently, the application of steel space frames for designing objects of any complexity is proliferating in world practice.The advantages of load-bearing space frames for large-span buildings are structural rigidity and geometric immutability, reliability and survivability, optimal material consumption, unification of elements and assemblies, choice in construction methods, visual “lightness” and aesthetics, freedom of internal planning, etc.This study aims to develop a variable model of a steel space frame which can enable the transformation of the interior space of large-span buildings. The research analyses the evolution of steel frames given the development of technologies and architectural and construction design; justifies the application of a steel space frame for a railway station building and develops a constructive scheme; examines the digital model of a steel space frame; develops a universal building block module; outlines the future research into the model application.The article describes the methodology of the steel space frame digital model development, stages and results of the experimental and theoretical research.
