The specifics of solving the spatial problem of calculating a large-panel building by the final element, associated with the need to calculate the matrices of the rigidity of the enlarged end elements, which in itself is a solution to a flat task, led to the separation of the general algorithm into two stages, which correspond to the gamma-3 and gamma-4 programs and gamut.
The Gamma-3 program implements the calculation of rigid characteristics for the final elements of the spatial system with the recording of the matrix of the rigidity of all the necessary types on magnetic tapes (ml) used in the future when operating the Gamma-4 program. In addition, according to the Gamma-3 program, you can calculate separate flat structures of large-panel buildings: stiffener diaphragms, load-bearing walls and ceilings, as well as individual panels with holes. According to the Gamma-4 program, spatial systems from orthogonally located flat elements (large-panel buildings, buildings from volumetric blocks, separate volumetric blocks and other similar spatial civil law systems for the assignment of the right of demand in the system of legal sciences) are calculated.
To take into account the specific properties of reinforced concrete as an elastic plastic material, a gamma-5 program has been developed, according to which spatial reinforced concrete core structures of the type of frame frames, taking into account the linear and nonlinear creep of concrete, shrinkage, cracking, displacement under the influence of the load and in the time of the neutral axis of the cross-sectional axis , changes in the process of loading efforts in the rods, the occurrence and closure of plastic hinges.
