New module in the Foundations and beddings chapter.
New options in different modules in the following chapters: Statis & dynamic analyses, stability, Foundations and beddings, Loads and actions, Timber structures.
New modules
Foundations and beddings
- Calculation of soil subsidence – module is used to calculate the subsidence of soil with account of soaking.
Enhancements to modules
Statis & dynamic analyses, stability
- Modules Rectabgular slab and Rectangular slab on elastic foundation. New option to calculate and generate contour plots of shear forces Qx and Qy.
Foundations and beddings
- Module Settlement of equivalent footing. New option to define arbitrary coefficient to limit the depth of compressible stratum.
Timber structures
- All modules of this chapter. New values for design strength are added according to SP 64.13330.2017, table 3.7.
Loads and actions
- Module Resonance check for wind turbulence. Modified according to SP 20.13330.2016.
- Module Wind loads. Modified calculation of aerodynamic coefficients for type of structures 13 Appendix D SP 20.13330.2016.
Sheet piling – the following options are added:
- to place H-braces;
- to define anchorage;
- to define horizontal loads, in particular, lateral pressure of water;
- to accumulate displacements by stages of calculation;
- to display the point of residual if there was a residual in solution of the system of equations;
- to save the file of assemblage table Name.mnt and text file Name.txt to format required for further analysis in LIRA-FEM program.
SOIL
- new option to calculate design resistance of soil R and generate the diagram for changing R value along the depth for arbitrary point under the foundation.

New program version is available - ESPRI 2018.
New modules
- Steel structures
- Critical temperature of section – module is used to determine critical temperature of heating in steel shapes for analysis of fire resistance. Eurocode 3 is supported.
- Foundations and beddings
- Disregard of soil resistance in earthquake – module is used to determine effective depth up to which soil resistance along the side surface of the pile is not considered in earthquake. SP 24.13330.2011 is supported with account of modification No.1 – sect. 12.4, 12.5 and sect. B.4 Appendix B.
- Properties of rubber metal damper – module is used to compute stiffness parameters of rubber metal solid and hollow blocks for earthquake protection of buildings.
Enhancements to modules
- Masonry and masonry reinforcing
- Analysis of brick pier. The following types of reinforcement are added: A240, A300, A400, A500, B500.
- Bruck pier by DBN V.2.6-162:2010. The following types of reinforcement are added: meshes from fibre-glass roving AKC600, AKC800 and meshes from basalt fibre AKB600, AKB800.
- Foundations and beddings
- Slope stability. The new type of analysis is added: cylinfrical slip surface with soil layer of great stiffness.
- Stability of multi-layer slope. New option to export points of the slip surface to the model of FEM for LIRA-FEM program.
