Input data for design modules
Perfectly rigid bodies (PRB) and offsets
When design model is generated, the dead weight of elements is computed. Load from non-load-bearing walls made of single-layer or multi-layer materials is computed. It is possible to create and edit concentrated, linear, surface loads (distributed uniformly and non-uniformly).
The following options are implemented: automatic collection of wind load, pulsation and earthquake loads, analysis of load from snow mound and collection of ice load according to different building codes.
There is a tool that enables the user to compute the soil pressure and apply it as a horizontal load to the walls of the basement. For a beam system, there is an algorithm that converts uniformly distributed load into load on beams. In the 'Edit load cases' dialog box, you could define the type of load case, safety factor, duration coefficient, sign variation, create groups of accompanying, united load cases and mutual exclusions. In this dialog box it is also possible to automatically generate tables of design combinations of forces (DCF), design combinations of loads (DCL) or create user-defined combinations.
Tools to collect loads
Ice load, snow mound, new options for wind load, generation of soil pressure. Data is transferred from VISOR-SAPR to SAPFIR to define the ice load, soil pressure. Collection of load on beams. Loads are applied to levels. Loads are applied to objects.
For the foundation slab, it is possible to define subgrade moduli C1 and C2 or take into account the soil model in the analysis by attaching it to the building model. In addition, pile foundation may be used. Bearing capacity of such foundation may be defined either as the load and settlement or the pile stiffness may be determined by a soil model. For a foundation slab, it is also possible to compute the compliance in horizontal direction.
Change FE type and define numerical stiffness
Triangulation lines and points
Intersection and triangulation
New settings for intersections of elements in the meshed model (SAPFIR 2020). Acceleration of triangulation. Triangulation lines. Triangulation template may be saved and used later for other projects. Vertical and horizontal triangulation lines for walls. Mesh refininement in areas near supports.
Model continuity and distance to supports
- Triangular - regular triangles are generated for all plates.
- Adaptive quadrilateral - triangulation starts from the supports and regular quadrilaterals are generated above supports.
- Quadrilateral - triangulation starts from a span and regular quadrilaterals are generated in the span.
Triangulation with a certain method and step may be assigned to specific objects. The triangulation mesh depends on triangulation lines and points.
Analysis and evaluation of output data
Output data (Analysis results)
New tools evaluate analysis results in SAPFIR 2020 in a simple way. Safety factors. Commands for check the correctness of design model: split storeys and distance to supports. It is possible to launch analysis from SAPFIR module and evaluate displacements, stresses, forces in elements by load cases and by DCL. Generation of DCL according to Eurocode EN 1991-1-4:2005.
