Industrial constructive system of civil buildings of increased survivability

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.
