Reinforced concrete (RC) structures

Enhanced algorithm for analysis of reinforcement with off-centre tension at small eccentricities (including by strength).

Analysis of reinforcement is optimized with account of fire resistance (now it is possible to avoid the significant increase in reinforcement in individual elements where the compressive or least tensile reinforcement was increased in cases of extremely small compression zones of concrete).

For the SP RK EN 1992-1-1:2004/2011, the condition "not less than 1.5 wall thickness" is added to the parameters for determining the min dimension of the end zone L_c of a plastic wall.

For plates, in the analysis for width of crack propagation by Karpenko method, the value Ψ_s=1 may be fixed now.
