esas.00; esas.01

## Linear statics 2D (esas.00)

Linear calculation in SCIA Engineer offers a professional tool for analysing two- and three-dimensional beam structures made out of steel, concrete or other materials. The program links the results from the steel and concrete structure analysis to various code checks.

- Linear static calculation of structures with members and/or plates (finite elements) loaded in the plane (e.g. frames, walls) or perpendicular to the plane (e.g. grids, floor slabs).
- Includes modelling and analysis of supports (fixed or hinged in nodes, on members and on plate borders), internal hinges in members and between plates, rigid connections, eccentricities, variable profile sections, variable plate thickness, etc.
- Load types: dead weight, nodal and concentrated loads, uniformly distributed and triangular loads, uniform or live loads, support displacements, temperature (uniform and gradient), etc.
- Automatic load combinations depending on the chosen standard, but user-defined combinations as well are possible.
- Results: numerical and graphic representation of displacements, support reactions, internal forces and stresses.
- Graphic representation with perspectives, cuts, details, isolines and isobands. All tools of the basic modules are available.
- Simplified user interface for simpler models such as plane frames with loads only in the structure plane or grids with loads only in the plane perpendicular to the grid plane.

#### Model

The user has access to a wide range of elements to generate an accurate model of the structure. These include:

- Beams and slabs;
- Fixed, hinged, rolling and elastic point and line supports;
- Hinges in beam and slab connections;
- Rigid links between nodes of the structure;
- Eccentricity of individual beams and slabs;
- Foundation blocks and strips on elastic subsoil;
- Haunches and arbitrary profiles;
- Variable thickness of slabs and ribs.

#### Load

Users can apply the following types of loads:

- Self weight. The program automatically calculates the applied load according to the beam cross-section and the material;
- Concentrated force and moment loads;
- Uniform or trapezoidal distributed force and moment loads on beams;
- Distributed loads on slab edges;
- Surface load on slabs;
- Eccentric load;
- Support displacement (settlements) and rotations;
- Temperature load (uniform or gradient);
- Absences of members and supports in certain cases (to simulate construction phases);
- Loads calculated from given layer composition of e.g. for floors;
- Climatic loads caused by wind pressure and snow weight.

#### Load combinations

The program can automatically generate design code (EC, DIN, NEN, ÖNORM, SIA, ČSN, etc) combinations. The user can also define his or her

own combinations if needed.

#### Clear and detailed results

- Diagrams on the model: diagrams of result values drawn on the model in 3D graphical window
- Resultants: loads, reactions, forces in sections
- Detailed results on separate members: detailed evaluation of results and diagrams member per member
- Comprehensive report about the calculation
- Engineering Report: combination of tables and pictures in a structured report

#### Comprehensive results

Beams and columns:

- diagrams
- resultants
- local and global extremes
- results on beams in user-defined fibres
- redistribution of bending moments

Slabs, walls and shells:

- izobands / izolines
- sections
- averaging strips
- resultants
- local and global extremes
- integration strips

## Linear statics 3D (esas.01)

As an extension of module esas.00, Linear static calculation of 2D members, this module enables the calculation of 3D beam structures, consisting of beam members and/or plates and walls (with module esa.01), curved surfaces (with module esa.02) or a combination of these elements. In the 3D-model, loads can have any direction.
