Inspection of Load-Bearing Structures of the Main Building of the Canning Factory

Abstract

Within technical re-equipment of the main building of canning plant there was a need of replacement of the capacitive equipment therefore load of overlapping of the first floor increased by 40.5 tons. In this regard, a comprehensive survey of structural structures was carried out. Defects and damages detected during the examination can in the future during operation lead to a decrease in the bearing capacity of the frame elements, and therefore to physical wear of the building. Therefore, taking into account the results obtained, it was recommended to implement a set of measures to restore struc-tures that were in a limited working condition.
 The check calculation of the structural structures of the first floor in the restoration room was carried out by the LIRA-CAD software complex, which is based on the method of co-engineering el-ements. When determining the forces for a monolithic beam-free plate, the most suitable loading combinations were taken into account. The most dangerous load in this case is considered to be the band load distributed over the entire span, and continuous when the pressure is distributed over the entire area of the structure. Considering the possibility of simultaneous collapse of the above column and span part of the floor, the calculation of the strength of the latter was carried out for strip de-struction.
 Based on the verification calculation taking into account the current state of the mill's construc-tion structures, as well as taking into account the expected increase in the load on them associated with the installation of new technological equipment, it can be concluded that the load-bearing ca-pacity of the structures is not provided.
