SAPFIR-Structures

Eliminated incorrect duplication of load on slab when the meshed model is generated. The load was duplicated if the thickening was defined along the slab contour.
Enhanced generation of horizontal and vertical triangulation lines for the openings in the curvilinear walls.
Enhanced import of user-defined sections (generated with Cross-section Design Toolkit) to the project library of SAPFIR sections.
Enhanced option to edit the snap type for walls when the lower level of wall is defined from the storey top.
Restored option to edit trusses through the control points.
Restored option to edit the punching shear contour manually (option to move the points of the contour).

Corrected import of analysis results to the Autodesk Revit model, added import of selected reinforcement from LIRA-FEM program when you work with Ukrainian language interface.
Corrected export of certain built-up steel sections from VISOR-SAPR to the *.STP format (for integration with Advance Steel DStV PSS).

Corrected error when the groups of coupled DOF are imported from the text file in case hinge supports for slabs are simulated.
Corrected imprecise presentation of the total intensity on mosaic plots of loads in case the surface loads are added to the block of loads when the elements are copied.
For the group of problems analysed in the Batch Analysis Mode, new option to check the pilot reinforcement for RC elements.
Enhanced algorithm for generation of physically nonlinear stiffness by results from analysis of reinforcement for elements:

for elements that became physically nonlinear, the following data is saved: input data for analyses of steel and RC elements, information about unification groups and structural elements;
when unification results for selected reinforcement are used together with piecewise linear stress-strain law (14), numerical values for parameters of nonlinear law are modified according to the current units of measurement.

Corrected option to convert the measurement units for nodal load of accelerogram type.
Corrected error in compatibility of files when you open problems in Demo version.

In geometrically nonlinear problems with progressive collapse that are defined with dynamic factors (quasistatic), now it is possible to carry out analysis of steel structures by design combinations of forces (DCF).
Enhanced import of results of the static and dynamic analysis for certain steel elements in case more than 300 static load cases are defined for the problem.
Enhanced analysis of steel structures according to AISC LRFD 2nd edition for the axially tensile elements.
Clarified the shear force for bearing capacity of steel beam according to Eurocode 3.1.1 EN 1993-1-1:2005/AC:2009.
Enhanced flexural-torsional buckling analysis of steel profiles according to Eurocode 3.1.1 EN 1993-1-1:2005/AC:2009.

Corrected analysis of reinforcement in plate elements with account of fire resistance according to STO 36554501-006-2006.
In analysis of RC elements, enhanced analysis according to SP RK EN 1992-1-1:2004/2011 'Design of RC structures'.

METEOR (Method of unified complete result) Enhanced options for MODEL VARIATION system. For the problems united in METEOR system by design combinations of forces (DCF+), arbitrary order is allowed for time history analysis, static & dynamic analyses.
