There are two different versions of PRO_SAP:
PROFESSIONAL: no limits in number of nodes.
LT: has the same functions of PROFESSIONAL version with a limit of a 500 nodes.

FREE VERSIONS are also available for who doesn’t own a license to test the program.


2S.I. in collaboration with University of Ferrara and CM2 – Computing Objects SARL, spin-off of the École Centrale Paris developed the latest generation e_SAP solver. Civil engineering specific functions, such as second order analysis effects and buckling analysis are immediately applicable. Non-linear step analysis ( load history ), large displacements analysis (cables, membranes, tensile structures,…) and dumper analysis, are some of the tools available to refine the structural design.


PRO SAP Professional SAP meets the requirements of every designer: PRO_SAP modules might be purchased individually for maximum customization.

Base Module: modelling and static analysis with truss, beam, pillar, membrane, walls, shell, solid elements, slabs, footings, foundation piles, insulators, damping systems. Linear static seismic analysis. Calculation report and maintenance plan.  BIM technology: import, export and update of interchange file IFC (Industry Foundation Classes)

Module 1: reinforced concrete design and verification (beams, columns, walls, slabs, shells) with ULS or allowable stress methods both for new and existing buildings. Calculation report.

Module 2: steel elements design and verification (beams, columns, trusses) with ULS or allowable stress methods both for new and existing buildings. Calculation report.

Module 3: seismic linear dynamic analysis, response spectrum analysis, buckling analysis.

Module 4: reinforced concrete construction drawing generation: beams, columns, walls and partitions, plates, slabs, floors, carpentry floor, stairs. Design and calculation report for footings and foundation piles.

Module 5: steel joints design and drawing generation: base plate, beam-column joint, continuity joint, beam-beam joint, bolted and welded carpentry. Design, drawing and calculation report.

Module 6: one-dimensional elastic-plastic truss only tensioned/compressed. Pushover analysis both for new and existing buildings, construction phases management, variable static pattern, nonlinear step analysis.

Module 7: masonry and timber structures design and verification with ULS or allowable stress methods both for new and existing buildings. Calculation report. Timber connection design, drawing and calculation report. Timber floors with connectors.

Module 8: concrete, steel and timber elements fire resistance verification according to the Italian and European codes UNI 9502, UNI EN 1992-1-2:2005, UNI EN 1993-1-2:2005 and UNI EN 1995-1-2:2005.

Module 9: geotechnical analysis, Winkler modulus calculation for superficial and deep foundations, settlement calculation. Geotechnical verification and report.

Module 10: new technologies design and verification: reinforced masonry, large lightly reinforced concrete walls, X-LAM cross-laminated timber, semi-prefabricated beams, FRP reinforcement for masonry and concrete structures.

Module 11: e-SAP 64 bit solver – e_SAPx64.

Other programs allows to design retaining walls, perform slope stability analysis and local interventions on industrial buildings with precast concrete structure.


PRO_SAP’s modules could be purchased individually to allows the maximum customization of the program, however PRO_SAP Professional SAP is available in two different and favourable application packages:

Standard edition: includes base module and optional 1 to 5. Enables design, verification, reports generation and drawings of reinforced concrete and steel buildings.
Advanced edition: includes the base module and the optional 1 to 10 and enables the design, verification, calculations and drawings with all the technologies operated by PRO_SAP.
