Abstract
The paper analyses the results of experimental studies of samples of rectangular plates working in two directions while resting them in the corners. The specimens combine with different materials: heavy monolithic concrete, prefabricated blocks of lightweight concrete, metal and composite reinforcement. The combined reinforcement allows to reduce weight of the specimens and gives new properties for structure during the operation. These properties are caused by different combinations of materials, their rational placement and peculiarities of physical and mechanical characteristics. Analysis of the results (indicators of strength, cracking resistance, deformability, schemes of fracture) was carried out by comparing the types of reinforcement, its amount, as well as changes in the strength of heavy concrete. It has been found that partial swap metal reinforcement (in the middle zone of slabs) for the composite reinforcement slightly reduces the strength, decreases rigidity and cracking resistance, and changes the mechanism of specimen failure.
This paper has clearly shown that the combined structure is promising due to reducing the weight, increasing the resistance to corrosive and dynamic impacts while ensuring reliability of construction in bearing capacity and rigidity.
