STRENGTHENING OF THE EXISTING BEARING STRUCTURE OF THE COATING

Abstract

 The solar power of the world is growing at an exponential rate and so today is an 
effective solution to the introduction of solar power plants. The installation of alternative sources 
should start with energy audits, building and facility surveys, project documentation development. 
Installation of new technical equipment on the roof increases the load on the supporting structures. 
In this regard, the supporting elements of the building frame need reinforcement. 
The  article  presents  the  results  of  visual  and  instrumental  examination  of  the  grain 
composition  located  in  the  agricultural  complex  according  to  which  deformations  of  the  cover 
structures were revealed. A necessary element of the survey is to check the design of the structures, 
taking into account their actual condition. Verification calculation of structures, taking into account 
the effect of defects and damages, was carried out with the aim of: possibility of further operation 
without any restrictions; the need to strengthen the structures. 
The object of the study is the existing metal structures of the beam type - the farm, and the 
subject  of  the  study  are  the  methods  of  rational  reinforcement  and  regulation  of  effort  in  such 
structures. 
Due to the increased load and insufficient cross-section of the farm elements, it is suggested 
to change the static scheme of the farm by installing additional elements of the grid - struts. 
 The calculation of the farm is to determine the longitudinal efforts in all its rods, which will 
later be used in the selection (verification) of the cross-section of its elements. 
The study was performed using classical calculations of construction mechanics and methods 
of  computer  simulation  experiment  in  the  software  complex  "Lira  CAD  2013",  which  is 
algorithmically based on the finite element method. 
The rational variant of strengthening of load-bearing structures is offered. 
The installation of solar panels on the roof of a building is possible provided that a working 
project is developed to strengthen the elements of the metal farm.
