LIRA-SAPR 2021 R1 Update 1 Release Notes

SAPFIR-Structures

• For triangulation points above the columns, new optionto define the same step as the triangulation step of the main slab.
• Enhanced option to save the file to previous versions of SAPFIR-3D.
• Fixed bug for visualization: objects of 3D view were not presented and it was necessary to generate new 3D view.
It is not allowed to use white colour for the stiffness of elements for which material is not defined. A random colour is assigned instead.

Large panel buildings

• Enhanced generation of nodes in case when the wall panels are connected in the middle of the storey.

SAPFIR-RC

• In the schedule of reinforcement, restored opton to define the reference document and class of material.

SAPFIR-GENERATOR

• Enhanced node 'Import SAF - Import of objects from the *.SAF file'.

• Plugin for two-way integration with Autodesk Revit is updated for Revit 2022.
• Added option to import hinges for bars from Revit model.
• When analysis results for reinforcement are imported to Revit, it is possible to import such results separately for bars and for plates.
• Restored option to intersect objects in SAPFIR module when the data is imported from Revit.
• Modified generation of DCF group E1 for problems with time history analysis and problems where analysis on progressive collapse is carried out by the quasi-static method.
• Added option to consider partial safety factors in analysis of reinforcement by forces of DCF group E1.
• Restored option to limit the depth of compressible stratum in case the soil with modulus of elasticity >100 000 t/m2 is located within such depth.
• Enhanced generation of the stress-strain diagram for concrete for group A1 according to results from analysis of reinforcement.
• Modified generation of DCL combinations for analysis on progressive collapse.
• Fixed bug in calculation of reserve factor for reinforcement during the check of PR types (Pilot Reinforcement) for the forces of group E1.
• In analysis of reinforcement according to SP 63.13330.2018 / SP 20.13330.2016, materials for specific combinations (without earthquake) are divided into:
  • type D1 [generated with load cases 'Specific except earthquake (6)', used to simulate special normative (design) * loads: fire truck driving onto the stylobate, extreme snow, wind, etc.) - if the corresponding check box is selected ** in the 'Type' materials, the normative characteristics of materials are applied (in this case, additional coefficients Yad, ϕ and ultimate strain specified in the materials 'Concrete' and 'Reinforcement' are not used];
  • type E1 [generated with 'Progressive Collapse (8)' load cases, used to simulate special emergency * loads) - if the corresponding check box is selected ** < / sup> in 'Type' materials, the normative characteristics of materials and additional coefficients Yad, ϕ and ultimate strain specified in the materials 'Concrete' and 'Reinforcement' are applied].

IMPORTANT. Subject to the above-mentioned changes, in problems with analysis on progressive collapse, generated in version 2020, it is necessary to do the following: for a quasistatic statement, to change the type of load case with a local failure (select 'Progressive collapse (8)' instead of 'Specific except earthquake (6)', and for dynamic statement on the 'Dynamics-plus' menu, select the DCF group of the generated dynamics results - E1.
