14 modules
Continuous Beam
The module enables you to carry out static analysis of multispan continuous beam (up to five spans with two cantilevers). Sections of spans may be different; it is possible to consider rigidity of support; arbitrary load may be defined for three load cases. Output data is presented as diagrams of displacements, rotation angles, bending moments and shear forces.

Influence Lines in Continuous Beam
The module enables you to generate influence lines for displacements, rotation angles, bending moments and shear forces from moving loads in multispan continuous beam (up to five spans with two cantilevers). Sections of spans may be different; it is possible to consider rigidity of support. In addition to standard normative loads (A8 and A11), you could define any type of moving load.

Truss
The module enables you to determine nodal displacements and forces in elements of plane trusses of various shapes that are most widely used in practice.

Parametric Plane Frame
Module for static analysis of plane frames of various shapes that are most widely used in practice. Output data is presented as diagrams of displacements, bending moments, normal and shear forces.

 Arbitrary Plane Frame
Module for static analysis of plane frames and trusses of various shapes. Output data is presented as diagrams of displacements, bending moments, normal and shear forces.

Rectangular Slab on Elastic Foundation
Module for static analysis of rectangular slabs on elastic foundation. Loads may be defined as uniformly distributed across the whole slab, across the specified surface, as linear and concentrated ones. Output data is presented as contour plots of forces and displacements as well as stresses in foundation. Their numerical values in the specified points will be displayed in the report.

Rectangular Slab
Module for static analysis of rectangular slabs with rectangular opening located anywhere. Supports may be defined anywhere on the contour. Loads may be defined as uniformly distributed across the whole slab, across the specified surface, as linear and concentrated ones. Output data is presented as contour plots of forces and displacements. Their numerical values in the specified points will be displayed in the report.

Wall-beam
Module for static analysis of wall-beams with rectangular opening located anywhere. Supports may be defined anywhere on the lower edge. Loads are defined along the upper edge as non-uniformly distributed or concentrated ones. Output data is presented as contour plots of stresses and displacements. Their numerical values in the specified points will be displayed in the report.

Shell on Rectangular / Circle Plan
Two modules for static analysis of convex parabolic, cylindrical, spherical and conic shells on rectangular and circle plans. The contour that the shell is supported by has rectangular shape. Loads may be defined as uniformly distributed across the whole shell area, across the specified surface, as linear and concentrated ones. Output data is presented as contour plots (in shell) and diagrams (in contour) of forces and displacements. Their numerical values in the specified points will be displayed in the report.

Mode Shapes and Frequencies of Natural Vibrations in Cantilever
The module enables you to calculate periods, frequencies and mode shapes of natural vibrations in cantilever bar. Cantilever may be divided into 50 non-uniform parts.

Stability Factors and Buckling Modes in Cantilever
The module enables you to calculate stability factors and buckling modes. Stability analysis is realized in classical elastic statement. Cantilever may be divided into 50 non-uniform parts.

Mode Shapes and Frequencies of Natural Vibrations in Continuous Beam
The module enables you to calculate periods, frequencies and mode shapes of natural vibrations in multispan continuous beam (up to five spans with two cantilevers).

Cable and String
Module for analysis of cables and strings. The module enables you to do the following:
- analyse cable by specified length of blank, by specified dip at mid-span or at any point;
- analyse string, including prestressed one.
Different types of load pattern are allowed, such as: concentrated load, different types of distributed loads as well as their combinations. Output data contains contains form of equilibrium, dip value, thrust, length of loaded elastic cable, diagrams of beam forces and axial force.
