Structural engineering program LIRA-SAPR 2013 R3 is available now.
User interface for SAPFIR-Structures module is presented in English. Now all main modules and components of LIRA-SAPR 2013 will have common language for interface for all (including non-cyrillic) language versions of Windows.
Main modifications and improvements in LIRA-SAPR 2013 R3:
modified dialog box for design combinations of loads (DCL). It is possible to change the dialog box size; coefficients for components of dynamic load cases are defined by default;
enhanced algorithm for calculation of design combinations of forces (DCF) for accompanying load cases;
for bars with variable cross section, new option to define groups of mutual exclusion in DCF;
enhanced option: considerably less time for generation of input data text files for problems that contain a great number of groups of coulped DOF, e.g. imported from MONOMAKH slabs and shells that are supported by walls;
modified option to copy stiffnesses and materials from one design model to another: it is possible to copy materials for several design options;
new option: when saving desing model, it is possible to automatically pack ‘empty’ perfectly rigid bodies (PRB) and groups of coupled DOF that contain less then two nodes;
new option: in contour triangulation mode you could obtain in series several triangulated fragments and not to return to the main window of program;
enhanced option: visualization of analysis results for bars in which reinforcement is not selected (for design models in which analysis of reinforcement in bar elements is carried out);
enhanced option: account of partial safety factor for concrete in analysis of reinforcement in plate elements according to SP 63.13330.2012;
enhanced algorithms for refreshing colour palette of reinforcement in ‘Zoom’ and ‘Fragmentation’ modes (RC and Steel structures mode of the program);
expanded list of user-defined colour settings for the scale that are saved to *.col files; new user-defined colour palettes for RC structures mode of the program;
great number of elements included into unification groups for automatic generation of nonlinear stiffnesses;
enhanced option: in analysis on earthquake loads by SNIP II-7-81 (dynamic module 20), coefficient K2 (table 4 SNIP) depending on number of storeys in the structure is taken into account and vertical inertial forces are calculated;
for design models with super-elements, recalculation of load on fragment from super-element is allowed;
for design models with super-elements, modified presentation of tables with results from analysis of reinforcement for separate super-elements;
restored option: for 64-bit version of LIRA-SAPR 2013, import of DXF floor plans;
restored option: for 64-bit version of LIRA-SAPR 2013, export of forces calculated in bar finite elements from VISOR-SAPR to Section of Bar module (SB-SAPR) and Section of Thin-walled Bar module (STB-SAPR).
added option: English language for user interface is available;
added option: check for location of walls and columns within the storeys. This check is helpful when objects and models are imported from *.ifc files. The check procedure is the following: if a column or wall is located geometrically within the limits of a certain storey, then after import from *.ifc file this wall or storey will be located just at this storey;
enhanced option: generation of physical models from bar structures (based on beams) by models obtained from VISOR-SAPR through *.txt file;
new option: to generate group of beams with the specified cross section across a set of selected lines;
expanded list of objects for which specifications may be generated. There are composite blocks that consist of structural elements of different types – beams, columns, bars of arbitrary location.
enhanced options for graphic editing of reinforcing members on sectional elevations and plans.
modified option: calculation of settlements of pile foundation for cases when depth of borehole is less than elevation of pile heel;
modified algorithm for generation of contour plots when determining contour plots on enlarged rectangular grid that describes load contours;
restored calculation of subgrade moduli C1 and C2 on enlarged grid that describes load contours.
LARM-SAPR module (analysis & design of separate reinforced concrete elements):
modified option: determining safety factors when you check reinforcement pattern in 64-bit version of this module for SNIP 2.03.01-84*.
SRS-SAPR module (Steel Rolled Shapes):
modified option: sort order for steels in certain files of steel tables.
