ARBAT is designed to select and verify existing reinforcement in reinforced concrete members (continuous beams and columns), and to calculate deflections in reinforced concrete beams in accordance with СНиП 2.03.01-84* “Бетонные и железобетонные конструкции” or СНиП 52-01-2003, СП 63.13330, ДБН B.2.6-98:2009, STR 2.05.05:2005, KMK 2.03.01-96, EN 1992-1-1.

Analysis is performed for the first and second groups of limit states using design combinations of internal forces (РСУ), selected automatically based on the specified loads in accordance with the applicable “Нагрузки и воздействия” standards.

Reinforcement selection and verification are available for reinforced concrete structures made of normal-weight, fine-grained, and lightweight concrete using various grades of reinforcing steel.

In addition to these functions, ARBAT also serves to some extent as a reference tool. It can be used to check data on reinforcement product ranges and properties, standard and design concrete strengths, concrete working-condition factors, and permissible deflection limits.

Compliance with СНиП is confirmed by a certificate issued by Gosstroy of Russia.

Reinforcement Design for a Beam

This mode selects reinforcement for continuous beams of constant cross-section (rectangular, T-shaped, or I-shaped), based on the first and second groups of limit states (strength and crack resistance). The beam is analyzed in plane. The following internal forces act on its sections : М - bending moment; Q - shear force.

The results include the areas of top and bottom longitudinal reinforcement, plus the area and spacing of transverse reinforcement bars. Symmetric reinforcement can be specified for rectangular and I-shaped sections.

Reinforcement Design for a Single-Span Beam

This mode selects reinforcement for single-span beams of constant cross-section (rectangular, T-shaped, or I-shaped), based on the first and second groups of limit states (strength and crack resistance). The beam is analyzed in plane. The following internal forces act on its sections: М - bending moment; Q - shear force.

The results include the areas of top and bottom longitudinal reinforcement, plus the area and spacing of transverse reinforcement bars. Symmetric reinforcement can be specified for rectangular and I-shaped sections.

Reinforcement Design for a Column

This mode selects reinforcement for a column of constant cross-section (rectangular, T-shaped, I-shaped, circular, or annular), based on the first and second groups of limit states (strength and crack resistance). The following internal forces act on the sections: N - axial force Мх and Му - moments at nodes; Мкр - torsional moment; Q - shear force.

The results include the areas of symmetric and/or asymmetric longitudinal reinforcement, plus the area and spacing of transverse reinforcement.

Reinforcement Design for a Cross-Section

This mode selects reinforcement based on strength and crack resistance. It is similar to the reinforcement design modes described above for structural members (beam, column, ...). The main difference is that selection is based on the internal forces in a cross-section.

Resistance of Reinforced Concrete Sections

This mode determines the load-bearing capacity of any supported cross-section based on reinforcement position, area, and grade; concrete class; service conditions; and allowable crack width.

In general, calculations account for axial force, bending moments, torsional moment, and shear forces acting in the principal planes of inertia. The member section is checked for the following conditions:

• strength under combined axial force and bending moment;
• strength under combined axial and shear forces;
• crack resistance under combined axial force and bending moment.
• crack resistance under combined axial and shear forces.

KROSS determines subgrade reaction coefficients for foundation structures on an elastic Winkler base by modeling a multilayer soil mass. The soil geology can be arbitrary and is reconstructed from geotechnical investigation data.

Its calculations are based on a settlement method developed at NIIOSP (V. G. Fedorovsky), which uses layer-by-layer summation and accounts for structural soil strength.

The model considers a construction site containing the planned structure and other objects (existing buildings and excavations) that can affect it through loads transferred to the ground, potentially causing foundation settlement. Geological investigation results are also assumed to be available as soil properties obtained from boreholes.

Interactive graphical tools enable arbitrary building configurations on the construction site.

Borehole locations and soil properties are used to create an on-screen soil profile.

The software outputs subgrade reaction coefficients at any point beneath the proposed structure.

Compliance with SNiP is confirmed by a certificate issued by Russia's Gosstroy.

MAGNUM is designed for structural analysis and verification of load-bearing cold-formed steel members under SP 260.1325800 and EN 1993.

MAGNUM performs design checks for bar members with user-defined section types and dimensions. If a member section is selected from a cold-formed profile catalog, the program can also select a suitable profile from that catalog.

MONOLIT designs monolithic reinforced-concrete ribbed floor systems consisting of slabs and beams supported by columns and/or walls. It was developed according to applicable standards (SNiP 2.03.01-84*, GOST 21.501-93, DSTU B A.2.4-7-95, GOST 21.101-97, DSTU B A.2.4-4-99, GOST 7473-94, DSTU B V.2.7-96-2000, GOST 14098-91, SNiP 52-01-2003, SP 52-101-03, SP 63.13330).

Compliance with SNiP is confirmed by a certificate from Gosstroy of Russia.

Floor layout

The overall floor layout is assembled on an orthogonal grid of consecutively numbered nodes. Nodes are positioned at intersections of floor members: beams, walls and columns. Constant-thickness slabs are assumed to align with the top of the beams.

Rectangular beams (or T-sections with a top flange) are divided into secondary beams receiving uniformly distributed loads from slabs and main beams carrying loads from transverse secondary beams. The floor is supported by load-bearing building walls and/or monolithic frame columns.

Support conditions depend on wall material: masonry walls allow freely supported beams and slabs without moment transfer, while concrete walls cast integrally with the floor provide rigid moment-resisting connections between the beams, slabs and supporting structure. All load-bearing components (walls, columns and beams) may be placed eccentrically to the axes joining layout grid nodes.

Reinforcement meshes and cages

This version supports reinforcement with individual straight bars (without bends), welded cages and meshes produced by spot-welding intersecting bars.

Results

The software generates a complete set of floor construction drawings: formwork plans with typical sections; top and bottom slab reinforcement layouts (mesh placement); beam reinforcement drawings; fabrication drawings of welded cages and meshes used in slabs and beams; parts schedules; steel consumption schedules for beams and slabs and a consolidated schedule; beam, slab and consolidated specifications; and required notes. Reinforcing components can be fully standardized within the subsystem.

Output documents

All output documents are prepared in standard A4 and A3 formats supported by most printers. Output to other formats and plotters is also possible.

For further editing, results can be imported into DXF files compatible with AutoCAD.

The software determines the factor of safety for slopes and embankments. Instability is modeled as sliding of a soil mass relative to the stationary portion of the slope. Shear resistance along the slip surface is calculated under static conditions. The soil failure criterion along the entire surface follows Coulomb's law.

The calculated actual shear stress is compared with the ultimate shear resistance, and the result is expressed as the factor of safety K. The slope factor of safety is the minimum value among all possible slip surfaces satisfying the constraints of the selected calculation method.

Input data includes:

• dimensions of the potentially sliding slope area;
• tension crack depth (if the tension-crack flag is enabled);
• soil properties;
• borehole locations and properties;
• loads acting on selected parts of the slope.

A report can be generated in RTF format from the analysis results.

Compliance with SNiP standards is confirmed by a certificate from Gosstroy of Russia.

KONSUL is used to create cross-sections and calculate their geometric properties based on the theory of solid bars.

Interactive graphical tools support complex sections of arbitrary shape, including holes, with features for smoothing corners, adjusting section outlines and vertex coordinates, moving selected groups of vertices, and more. It can import sections from DXF and DWG files and work with user-defined parametric sections.

The calculation returns cross-sectional area, moments of inertia, radii of gyration, section moduli, torsional and sectorial properties, and the coordinates of the shear center.

Normal stress fields can be calculated when internal forces in the section are specified.

The resulting geometric properties can be used in SCAD to define element stiffness characteristics.

Section Designer creates arbitrary built-up sections from rolled steel profiles and plates and calculates the geometric properties required for structural analysis.

For a designed section, it determines:

• cross-sectional area A;
• moments of inertia Iy and Iz about centroidal axes parallel to the Y and Z axes of the right-handed Cartesian coordinate system;
• radii of gyration iy and iz about the same axes;
• free torsional moment of inertia It;
• centroid coordinates;
• angle of inclination of the principal centroidal axes (angle a between U and Y);
• maximum Iu and minimum Iv moments of inertia;
• maximum iu and minimum iv radii of gyration;
• maximum Wu+ and minimum Wu- section moduli about U;
• maximum Wv+ and minimum Wv- section moduli about V;
• core distance from U measured in the positive (au+) and negative (au-) V directions;
• core distance from V measured in the positive (av+) and negative (av-) U directions.

Calculations follow standard strength-of-materials rules. The free torsional moment of inertia is approximated as the sum of the free torsional moments of inertia of the profiles making up the section.

Assembly

Section Designer provides these assembly methods:

• connect a reference node of an element to a reference node of another section element;
• connect a reference node of an element to a section point specified by Y and Z coordinates;
• connect an element by aligning lines between two reference points on the inserted element and the active section element.

With the first two methods, an element is inserted with the specified orientation. When connecting along a line, its orientation depends on the directions of the lines being joined.

The overall dimensions of the assembled section are continuously monitored.

Report

A report is generated from the calculated section properties as an RTF (Rich Text Format) file. Once generated, the application associated with RTF files (such as MS Word or WordPad) opens automatically.

Export results

Calculated geometric properties can be exported to Structure CAD (version 7.27 and later) and the KRISTALL steel member analysis and verification system (version 2.1 and later).

Section component information

Dimensional information is available for rolled profiles used to build the section.

The Sezam program is designed to find a cross-section of the box, I-beam, T-beam, or channel type that most closely approximates a user-specified cross-section based on its geometric characteristics. The source cross-section can be specified as a file generated by Consul, Tonus, and Section Builder, a set of geometric characteristics, or a composite cross-section from the program's set of prototypes (e.g., two channels, two I-beams, etc.).

The following characteristics are approximated for the specified cross-section: area, principal moments of inertia, and moments of resistance. User-specified weighting factors are also taken into account.

The Tonus program is designed to generate sections and calculate their geometric characteristics based on the theory of thin-walled rods.

Graphical interactive tools enable the formation of arbitrary (including open-closed) thin-walled sections.

The program provides for the import of sections from DXF and DWG files, as well as work with parametric sections specified by the user.

As a result of the calculation, the following characteristics can be obtained: cross-sectional area, values ​​of moments of inertia, radii of inertia, moments of resistance, torsional and sectorial characteristics, coordinate of the bending center.

The program allows you to obtain normal stress fields if internal forces in the section are specified.

The calculated geometric characteristics can be used in the SCAD complex when specifying the rigidity characteristics of elements.
