Malyushitskiy O. Strain-stress distribution and resistibility of CRC (composite reinforced concrete) architraves' node concrete inserts

The subject matter - concrete inserts of composite reinforced concrete frames' nodes; aim - investigation of the work of concrete inserts of composite reinforced concrete frames' nodes and working out recommendations on their analysis and design on the basis of completed theoretical calculations and pilot researches; novelty -mathematical method of design of concrete inserts of composite reinforced concrete frames' nodes has been given next step forward; problem-solving in defining the boundary load on concrete inserts of composite reinforced concrete nodesin frames that work in shear,has been improved when employing variation method of the concrete's plasticity theory; outcome -' designing methods of land ties with variable cross-section in concrete inserts of composite reinforced concrete frames' nodes has been greatly improved and developed; there have also been received new experimental findings of investigation of strain-stress distribution, load-carrying ability and fracture mode of flexible land ties in concrete inserts of composite reinforced concrete frames' nodes; branch - building and construction.
