To reduce energy resource consumption in construction industry, housing and utilities infrastructure, it is necessary to maximize the new structural solutions use for the buildings and structures. The bearing and enclosing structures functions separation allows using the optimal design scheme with minimal steel spread for the supporting structures and effective modern thermal insulation materials for the enclosure. The advantages of grid shell structural system are durability, seismic stability, easy installation, dismantling, transportation, re-installation without the heavy equipment use; it also can be used in remote and hard-to-reach places. The authors propose the modules that can be used as exhibition pavilions, shops, cafes with the room height up to 6 m. Mass production of grid shell domes became possible with the advent of computer-aided design, allowing to perform the calculation and the structure three-dimensional model.
The article addresses solving the issue of the possibility of preserving reconstructed premises or carrying out proposed reconstruction works in the course of in the course of construction forensic investigation. The significance of the problem attributes to the volume of the stock of residential and public buildings which are older than 40 years (according to statistics, the housing stock of Russia in 1980 was 1,861 million m2 , in 2015 – 3,581 million m2 ), outdated layouts of premises, and the evolved consumers’ idea of comfort.A construction expert’s task is to determine if there is a possibility to change the layout, the function of premises to improve living conditions, or reconstruction poses a threat to the state of the object, its further proper operation, the integrity of the installed engineering systems, the appearance of the facades, nearby buildings and structures. Using regulatory material, the authors consider the criteria for solving this problem, present the procedure for conducting studies of buildings or structures, building materials, structures, and relevant documents in this line of forensic construction examination. Finally, the article gives specific examples of the redevelopment of apartments, a proposed reconstruction of the kindergarten premises.It is noted that the reliability of experts’ opinions is based on a comprehensive, unbiased analysis of all the technical and economic characteristics of construction objects, verification of documentation, an inspection of structures for compliance with the requirements of federal laws, rules, and regulations.
The article gives an analysis of the results of studies of the operation of rolling profiles after a local thermal action.
