Information – Eurocode design software with national application for Bulgaria. Design of slabs, beams with rectangular or T-sections of plain and lightweight concrete, columns of rectangular or circular cross-section at double bending pressures. Reinforcement with polymer fibers (FRP). Check for sagging and cracks. Beam spherical model with pressed part and tensioners (Eurocode2, §5.6.4, §6.5). Tables and diagrams according to Eurocode 2 – Kd, med ω, effective length. Beamless slabs, foundations, pools, arches. Interaction diagrams for ultimate strengths of biaxial bending and pressure. Dimensional diagrams for sag control. Detailed tables of reinforcement and export of results in PDF or WORD are compiled. Engineering tools for conversion of measuring units, calculations of areas, characteristics of arbitrary cross-section and from the library, reinforcement-anchoring, areas, coefficients of earth pressure. Wooden roofs, floors, joints, wooden-concrete slabs. Wooden round and rectangular sections for bending under pressure, bending when bending, fire resistance by the method of reduced cross-section. Dimensioning of steel beams and columns, steel single-story and two-story frames.
