New technology ‘Tekla Structures — LIRA-SAPR — Tekla Structures’ is introduced. It allows the user to generate the model in Tekla Structures, then import it to LIRA-SAPR, carry out static and dynamic analyses, select sections of elements and reinforcement, export analysis results to Tekla Structures and further obtain detail drawings (for reference, in Russian - drawings KMD) and CNC.
Unified graphical user interface (GUI)
New option to work with several tables of DCF and DCL within the same problem. The user is provided with the simple and convenient tool to carry out multi-variant analyses and comparative evaluation of analysis results obtained for different building codes (traditional SNIP and updated SP), by varying logics to consider accompanying and mutual exclusion of load cases, applying different sets of combination coefficients. There are also more ways to generate design options. The user could select appropriate DCF or DCL table for certain design option and define different material properties as well.
Options of graphical visualization of analysis results are dramatically enhanced.
- For displacements and forces, it is possible to preview extreme (min and max) values selected from all defined load cases or DCL. Obtained envelope lones are presented as diagrams and mosaic plots.
- Graphical presentation of analysis results for DCF calculation. Design and normative DCF (complete and live) are presented on the model as mosaic plots and envelope diagrams of extreme values.
- For analysis of RC structures with ‘NL Engineering’ system, it is possible to generate mosaic plots of integral stiffness parameters for bars and plates.
No limitations on possible number of specified load cases as it was in previous versions (not more than 96 load cases when DCF and METEOR systems are used, otherwise not more than 300 load cases). These limitations are removed for all types of analyses.
New option to compute rigidity centre and centre of gravity for the fragment (storey). The user could quickly and visually evaluate potential for torsional vibrations in dynamic (earthquake) loads and modify arrangement of design model, if required.
More options to select objects on design model. Now the user could select nodes and elements by clicking (or dragging ‘selection window’ across) appropriate ranges on colour palette, construction lines and levels.
Information presented in the dialog boxes about selected node/element is considerably updated and expanded. In the mode of analysis results, it is possible to evaluate information about displacements or forces obtained in any of computed DCF and/or DCL tables.
New option to compute deflections for bars and plates relative to node with zero relative displacement (specified by the user on the model). Diagram of deflections is presented in a separate window and may be saved to the Report Book.
No limitations on number of nodes when you generate perfectly rigid bodies (PRB). In previous versions, one PRB could include not more than 200 nodes.
New ‘Characteristic DCL’ method. It enables the user to considerably reduce time during check and selection of reinforcement and steel sections. The efficiency of this method is observed with increase in number of specified DCL. If number of DCL is more than 100, time of analysis is reduced in 10 or more times.
New technology for defining materials for RC structures. When you define new parameters, it is possible to preview and evaluate all previously defined data for concrete, reinforcement and design requirements. There is common interface to define material properties in VIZOR-SAPR and SAPFIR-Structures modules.
Enhanced technology for generation and editing surface loads. Data connection between parameters of surface loads and parameters of appropriate groups of concentrated loads. The name is assigned to every surface load. This name may be modified later. It is possible to preview surface loads and modify its intensity.

Analysis of reinforced concrete (RC) structures
In plate elements, it is possible to analyse reinforcement using different concrete covers for differently directed reinforcement.
For plate elements in compression (wall, diaphragm), reinforcement may be analysed with account of slenderness in vertical elements (effective lengths are defined in the similar way as for bar elements in ‘Materials’ section).
Analysis of steel structures
New option to simulate pile with the chain of vertical bars. Vertical and horizontal stiffness of soil are simulated with finite elements located at nodes of this chain. The stiffness values are computed automatically according to properties of 3D soil model. Then you will be able to obtain diagrams of forces N, My, Mz, Qy, Qz along the whole length of pile and analyse reinforcement in pile. Upper bar in the chain – pile head – may simulate hinge or rigid support of foundation slab on pile.
The program takes into account mutual integration of piles according to method presented in the ‘Analysis of settlement of pile bunch’ chapter, sect. 7.4.4, 7.4.5 SP 24.13330.2011 'Pile foundations'.
The program automatically generates FEs that are located along the edges of the specified soil model and simulate the soil beyond its limit. Stiffness of finite elements is calculated automatically according to adjacent layers of the generated soil model.
Enhanced options in METEOR system. With integrated problems, you could design not only by DCF but by characteristic DCL as well.
In material properties of SAPFIR, there is new option to assign design parameters that will be considered as input data for analysis of reinforcement in VISOR-SAPR module. These parameters are assigned automatically to structural elements according to material properties. Later the user could modify design parameters for every structural element separately.
New ‘Load cases’ dialog box that includes Load case editor, tables of input data for DCL and DCF. On the ‘Edit load cases’ tab the user could generate a set of load cases, assign the type and subtype of safety factors, duraction factor, mutual exclusion, unification, accompanying and sign variability. Data from the ‘Edit load cases’ tab is used to automatically generate combinations of loads (DCL and DCF). DCL and DCF tables are generated according to building codes SP 20.13330.2011, DBN B.1.2 - 2:2006, SNIP 2.01.07 -85*. All combinations are generated based on the data from the ‘Rules for combinations’ dialog box that contains a set of coefficients and formulas to generate both normative and user-defined combinations. Above-mentioned parameters may be saved to file and used in other projects.
New tool to define earthquake load according to the following building codes: SP 14.13330.2014, DBN B.1.1-12:2006 and SNIP II-7-81*. All parameters for the earthquake load are defined in the same dialog box:
- direction of earthquake load;
- units of magnitude;
- soil category;
- number of mode shapes;
- type of structure;
- all appropriate coefficients of the building code in use;
- load cases that generate masses for earthquake analysis.
These parameters are used in earthquake analysis in VISOR-SAPR module and no additional data is required.
The user could define several earthquake load cases in different directions.
Detailed analytical model of the stairs may be generated. Stairs from RC are simulated with plates while stairs with saddles and strings are simulated with bars of the specified section. Dead and live loads may be defined to the load-bearing elements of stairs. It is also possible to define boundary conditions at places where these elements intersect the framework of a building.
Additional lines and points of triangulation for slabs may be defined and modified at the stage of model generation.
New object ‘Pile’ is presented: vertical bar of the specified cross-section; its stiffness is defined as bearing capacity and settlement. It is possible to arrange either single piles or pile groups in an ordinary or staggered type – along the line (strip) or inside arbitrary contour. Parameters for the pile group (e.g. step, number, contour line, etc.) may be modified. Location of piles is taken into account during triangulation of foundation slab in design model. When piles are transferred to VISOR-SAPR module, appropriate FE type is assigned to them.
Option to save *.spf file for previous versions of SAPFIR program: SAPFIR 2015, 2014 and 2013.
Enhanced functionality for the ‘Grid lines’ tool. The user could define arbitrary name for the line in the grid, automatically modify dimension of mark in case of long name. With the ‘Explode block’ command, grid of lines may be transformed to the set of single lines.
Grid lines may be visualized at the level of active storey. In parameters for line it is possible to define the storeys where the line should be visualized.
For columns and beams, snap point of the section may be chosen graphically.

For foundation slabs, pattern of dowels for vertical elements (columns and diaphragms) may be generated on the basis of concepts developed at the stage of design of these elements (in SAPFIR-RC Column, SAPFIR-RC Diaphragm modules) that are supported on foundation slab. Specifications for reinforcement dowels are presented, drawings of joints and their location on plan of foundation slab are generated.
Cross-section of reinforcement in slab may be presented with notations for location of rebars of main and additional reinforcement, technological reinforcement and (for foundation slabs) dowels to vertical elelements (columns, diaphragms).
New tool to unify reinforcement in slabs. This tool enables the user to evaluate and compare analysis results for reinforcement in identical slabs in order to find out slabs with similar reinforcement pattern and unite them into unification groups. When unification groups are generated, superposed contour lines for area of reinforcement in several selected slabs may be visualized simultaneously. Numerical values are presented in the table. The common mark is assigned to slabs in the same group. To design the prototype of unification model, the envelope line with analysis results for reinforcement is generated. It displays max values for area of reinforcement obtained in analysis of all samples of slabs with this mark.
