Abstract
Investigation by digital technologies of the transverse force in a reinforced concrete roof beam reinforced with a channel
Incoming article date: 14.03.2022The essence of the proposed is the arrangement of the frame from the channel around the coating beam. At the same time, the frame elements can be subjected to controlled effects, in the form of overvoltage in them, which is realized by specially installed traction brackets. The study of the proposed structural and technological solution, implemented by a channel frame, was carried out using digital technologies based on numerical modeling. In the proposed calculation model, the beam reinforcement area was changed due to the introduction of a reinforcement frame. In the Etabs software package, using the finite element method, transverse forces and moments were calculated in the newly formed system - a beam plus a channel frame. The paper considers the issue of the influence of the frame on the transverse force in the beam. Using the technology of processing large arrays of numbers, a mathematical model of the process was obtained when the beam was reinforced with a channel frame. A consistent analysis of the mathematical model was carried out, which allowed to state the correctness of the decision and assign the design dimensions of the device and its technological parameters.
