Title of the articleDefining operational parameters of reinforced concrete structures in a building without their physical destruction by full-scale tests
Abstract.The main operating parameters of reinforced concrete structures are the strength, stiffness and fracture toughness. The quality of the products on these indicators is established on the basis of the results of control tests by loading to failure in accordance with the requirements of normative documents and working drawings. However, deformation of structural elements in a building, taking into account their joint work is different from the settlement schemes of loading. The actual definition of quality parameters becomes an urgent task in the reconstruction maintained buildings, changing their destination and especially with increasing operational loads. The authors proposed a method of determining the actual quality parameters structures operated in the building by actual tests without their physical destruction. The methodology is based on state diagrams of concrete and reinforcement, which is obtained by testing samples of materials. In the structures under test is measured deformation and charts materials are determined voltage. Maximum stress values determined by the value of the actual conditional ultimate load. Depending on the nature of the contingent destruction is assigned a safety factor and is calculated design load. A program was developed and conducted field tests of slabs in the composition of the occupied buildings. The developed technique was evaluated actual quality parameters and the calculated values of the maximum allowable operating load on the floors of the building considering changing its purpose.
Keywords.full-scale tests, reinforced concrete design, quality parameters, stress, strain, design load
