Abstract
The paper considers a new industrial constructive system of residential and public buildings that meets modern requirements for protection against progressive collapse, improved space-planning, architectural and thermal protection solutions. The presence of a significant number of enterprises with technological lines for the production of structures for large-panel housing construction and their share in the market, combined with a number of shortcomings of the technical and space-planning solutions used, indicate the need to modernize these enterprises for their production to meet modern requirements. The purpose of this study was to develop an industrial constructive system of civilian buildings with increased resistance to progressive collapse, the production of which would not require expensive modernization of the construction industry enterprises. Based on the level calculation schemes, an algorithm is proposed for calculating such a system for a particular emergency impact. Numerical studies have established the correspondence of the developed constructive system to the requirements of a special limiting state under design loads and accidental effects caused by the disconnection of the vertical bearing from work.
Highlights
The development of new types of constructive systems of residential and public buildings that meet modern challenges remains one of the urgent problems of modern construction [1,2]
The country has a significant number of house-building enterprises with technological lines for the production of structures for mass large-panel house building, which in the total volume of housing construction in many regions of the country make up 50-65% or more [8]
The aim of the presented work was the creation of a new industrial structural system of residential and public buildings of mass construction with enhanced protection against progressive collapse, improved space-planning schemes and high capabilities of thermal protection solutions and architectural expressiveness of facade systems of buildings
Summary
The development of new types of constructive systems of residential and public buildings that meet modern challenges remains one of the urgent problems of modern construction [1,2]. The country has a significant number (over 250) of house-building enterprises with technological lines for the production of structures for mass large-panel house building, which in the total volume of housing construction in many regions of the country make up 50-65% or more [8]. In this regard, the improvement and creation on this basis of new industrial constructive systems of buildings with enhanced protection against progressive collapse for mass construction is a current trend
