INCREASING SAFETY DURING STATISTICAL TESTING OF BUILDING STRUCTURES (BEAMS, LOADS)

Abstract

The article examines the current problem of ensuring safety during statistical testing of rack structures, in particular beams and supports. Any metal structure wears out during operation. The effects of overload, deformation, and various damage become visible. Periodic checks help determine how worn out the equipment is. The scope of repair work is determined and financial losses associated with the breakdown of commercial products after a rack fall are prevented. Such checks help prevent accidents and human casualties and extend the service life of racks. Finding a balance between testing efficiency, compliance with regulatory requirements, and worker safety is accomplished by changing the way and method of performing work. The proposed method consists of conducting mandatory periodic tests of racks (beams, supports), possible by their operators or owners without the use of heavy loads that require metrological verification and storage space and create the need for physical overload of workers.

         The fixed static load is represented by traction forces from 0.1 to 1.1 times the standard load capacity of the racks (beams, supports), created by a lifting mechanism, measured by a dynamometer and transmitted to the racks through single-branch slings connected by end elements to the attachment points of the test objects and stretched parallel to the plumb line to set the vertical direction of the traction forces.

        This significantly improves test safety, reduces the risk of accidents, and enhances the reliability of the results. The findings can be used to update regulatory and technical documentation and raise safety standards in the construction industry.
