Different methods of structural analysis

The structural analysis can be carried out:

• First order, by load case
• First order, by load combinations
• Second order, always by load combinations.

Generation of the structure geometry by typologies

The geometry and members of the structure are entered using a typology generator associated with different standard structures, such as:

• Plane and spatial orthogonal building frames.
• Arches and continuous beams
• Trusses: Pratt, Howe, Warren and St Andrew’s cross
• Space grids
• Towers with different types of triangulation

Automatic generation of loads on roofs and industrial buildings

Based on the geometry and site conditions, the program internally determines the following loads:

• Permanent load
• Maintenance
• Snow
• Wind (transverse and axial)

Wind loads

As a result of the automatic load generation, the program internally assigns the different wind loads to each member in accordance with the Spanish Technical Building Code (CTE).

Interactive purlin design

The program internally selects or checks the roof purlins using an interactive screen.

Analysis of global buckling and vibration of the structure.

For each load combination, the program determines the critical global buckling factor, its buckling mode and the buckling lengths of the members. And also, if requested, the lowest vibration frequency and its modal displacements.

DXF files

An example of the DXF generated by the program for a duo-pitch portal frame is shown.

Data can also be entered by importing DXF files.

Deformations

The program allows the integrity, comfort and appearance deflections of the structure, calculated in accordance with the CTE, EAE and Eurocode, to be displayed graphically. By holding down the left mouse button and dragging it over the structure, a text box with the deformation data by segment can be viewed on screen.

Utilisation ratios

By selecting “normal stress ratio”, the utilisation ratios of sections and members can be seen visually thanks to a colour scale. This shows directly and visually whether the entire structure is valid in terms of strength.

GRAPHICAL REPRESENTATIONS

Solid modelling

The program can display the structure, or some of its parts, representing the members as solids**.**

Composer for plane and spatial structures

Starting from an already defined structure, the rest is completed if it can be generated by repeated translation or rotation of a plane base module of the structure. The nodes and members of the new structure are numbered internally by the program.

CONNECTIONS AND SUPPORTS

Member end releases

Any type of member end connection corresponding to a hinge about any of the principal axes of the section can be selected.

Different support models in plane and spatial structures

Selection of different models of fixed or elastic supports (defined by the spring coefficient corresponding to the selected direction, for plane and spatial structures).

DIFFERENT MEMBER MODELS

Tie members

All members defined as ties “T” are highly slender and can only take tensile forces, so if they are in compression they are cancelled internally in the corresponding load combination and therefore take no force at all.

Tapered members

Tapered (variable-section) members are supported in both steel and timber.

Built-up members

In steel structures, battened built-up members can be used, and in timber structures: members with blocks, spacers or battens.
