Update 1 for LIRA-SAPR 2020R1 is available. Updated options and features: fragment from SAPFIR, *.csv tables, Time History Analysis, DirectX graphics, 'Method 10%', AMD processor, fire resistance, surface loads, 6th DOF, safety factor.
- Enhanced options: recognition of multi-span beams when importing the *.ifc file and restoring their geometry in the case the Boolean operations were applied to the beams in the source file.
- Enhanced import of *.dxf floor plans: generating windows, walls and partitions. If a layer was assigned the corresponding layer name in AutoCad and the objects were drawn along the contour (walls, columns, piles), then the 'Contour' option is automatically set for the import to SAPFIR module.
- Fixed: difference in storey heights when importing *.ifc and LiraKM files from Revit.
- Restored: option to import several *.ifc files into separate projects during one work session.
- Fixed: recovery of the physical model *.spf file according to the meshed model *.lir file if there were layers and storey levels in the meshed model.
- Added: option to define the ice load for columns.
- Settings for the line weight for columns may be also applied to capitals.
- In addition to the previous options to define the snow mound according to SP 20.13330.2016, now it is also possible to define the snow mound according to SP 20.13330.2011. Parameters defined in calculator (building code, snow area and parapet height) may be saved to use further during the work session.
- Fixed: generation of load from soil pressure in case there are openings in walls.
- Fixed: thickness of column base is transferred to VISOR-SAPR module correctly.
- Enhanced: snap of the premises to intermediate levels of storey.
- Fixed: duplicate beams included in the beam system when the meshed model is generated.
Large panel buildings
- Restored: FE of platform joints located in the wall openings are automatically excluded from the analytical model.
- Added: rebars may be located along the pile height.
- Restored: types of pilot reinforcement (PRT) for walls created in SAPFIR-RC module may be transferred to VISOR-SAPR module.
- Restored: the spacing of the studs and bend to the stud for wall reinforcement may be defined as default values. Class of reinforcement and the diameter of studs are added to default settings.
- Added: support of GOST 34028-2016 for individual rebars and reinforcing items.
- For the section by model of wall reinforcement, tag leaders are not generated for rebars that are not included in the section.
- Restored: reinforcing items (L-shaped elements, U-shaped elements) may be generated on the plans of vertical elements and on 2D detail views of wall reinforcement.
- Enhanced: presentation of wall reinforcement on 3D view for cases when the wall is snapped to the left or to the right of the axis.
- Added: the type of anchorage at the ends may be selected for a group of rebars in the model of beam reinforcement.
- Fixed: presentation of main reinforcement in the slab along the X-axis and along the Y-axis.
- Enhanced option to copy loads that are defined as a property of the slab when the 'Multi-copy by storeys' node is used.
- Fixed: snap of the base point of the door when copying the door node.
- Fixed: warnings from OS when the fragment from SAPFIR module is added to LIRA-FEM project and then the model is packed.
- Corrected: table with results of reinforcement for RC elements in the *.csv format for problems where analysis results are saved in a separate folder (selected option).
- Fixed: warnings from OS when work with the 'Edit load cases' dialog box if there is no load case with the damping properties (for problems with Time History Analysis).
- For DirectX-based graphics mode, clarified recalculation of overall dimensions for the structure when new nodes are added to the model.
- Mosaic plots of nonlinear stiffness for 2-node FE of elastic springs with account of ultimate forces (FE 255) is still visualized when the load case number is changed.
- Fixed: possible errors on English versions of Windows OS in case Cyrillic names of *.LIR files are used when you work in the English interface of LIRA-SAPR.
- Corrected: endless DCF calculation when 'Method 10 %' is used to compute the total component of dynamic load (for problems with earthquake load cases).
- Fixed: possible abnormal termination of DCF calculation (for computers with AMD processors with a large number of logical processors (more than 20)).
- Fixed: initial presentation of super-elements in the active window for DirectX based graphics when super-elements were added to design model.
- Enhanced: presentation of mosaic plots with fire resistance parameters for RC bars specified with account of fire resistance.
- Restored: contour lines of plates are redrawn when visualization parameters for offsets in plates are modified in the 'Offsets in plates' dialog box.
- Fixed: correction factor for a surface load is considered when load cases are copied.
- Clarified: FE analysis results for wall-beams with the sixth DOF (rotation about the local Y1-axis).
- Corrected: difference in safety factors obtained in analysis of pilot reinforcement in VIZOR-SAPR module and in local mode of reinforcement for the element (for DBN B.2.6-98:2009).
