Calcul Piloti – Conform SR EN 1997-1: Capacitatea portanta ultima la compresiune stabilita pe baza rezultatelor incercarilor asupra pamanturilor:
Capacitatea portanta de calcul Rc;d a unui pilot se obtine folosind relatia:
Rc;d = Rb;d + Rs;d
Pentru fiecare pilot, valorile Rb;d si Rs;d se obtin astfel:
Rb;d = Rb;k/γb si Rs;d = Rs;k/γs
Valorile caracteristice ale Rb;k si Rs;k se determina folosind relatia:
Valorile caracteristice pot fi obtinute astfel:
Rb;k = Abqb;k Rs;k= ∑As;tqs;t
Conform SR EN 1997-1 abordarile de calcul pentru piloti sunt:
ABORDAREA 1:
Gruparea 1: A1 + M1 + R1
Gruparea 2: A2 + (M1 sau M2) + R4
ABORDAREA 2:
A1 + M1 + R1
ABORDAREA 3:
(A1 sau A2) + M2 + R3
SR EN 1997-1-2006/NB-2008 recomanda utilizarea doar a abordarilor 1 si 3.
Coeficientii partiali de rezistenta pentru fundatiile pe piloti conform SR EN 1997-1 Anexa A sunt:
- γb pentru rezistenta pe varf
- γs pentru rezistenta prin frecare pe suprafata laterala a pilotilor supusi la compresiune
- γt pentru rezsitenta totala/combinata a pilotilor supusi la compresiune
- γs;t pentru rezistenta la frecare pe suprafata laterala a pilotilor supusi la tractiune
Tabelul 1: Coeficienti partiali de rezistenta (γR) pentru pilotii de indesare
Tabelul 2: Coeficienti de rezistenta (γR) pentru piloti forati
Tabelul 3: Coeficienti de rezistenta (γR) pentru piloti cu burghiu continuu (CFA)
Coeficienti de corelare pentru fundatiile pe piloti conform SR EN 1997-1-2006 Anexa A sunt:
- ξ3 pentru valoriile medii ale rezistentelor calculate pe baza incercarilor asupra pamanturilor
- ξ4 pentru valorile minime ale rezistentelor calculate pe baza incercarilor asupra pamanturilor
Tabelul 4: Coeficienti de corelare pentru stabilirea valorilor caracteristice pe baza incercarilor asupra pamanturilor (n numarul de incercari)
Piloti si micropiloti-MP
Piloti si Micropiloti este un program pentru calcularea capacitatii portante a terenului de fundare pentru un pilot sau micropilot ce sustine o oarecare combinatie de sarcini (moment, forta normala, forfecare). Programul realizeaza, de asemenea, calculul structural dimensionand armaturile.

http://www.geostru.eu Filippo Catanzariti (b. 4 June 1969, Calabria, Italy) is a civil engineer, software developer and entrepreneur.
He graduated in Civil Engineering, geotechnical track, at the University of Calabria in 1996, with a thesis entitled "Programma di calcolo per l'analisi della stabilita dei pendii con metodi numerici avanzati" (A calculation program for slope stability analysis using advanced numerical methods) - the work that became his first commercial product. He has been registered with the Order of Engineers of Reggio Calabria (no. 1839) since 1996.
From 1996 to 1999 he worked as an analyst and software developer specialising in numerical algorithms, in Pascal, Visual Basic, Fortran and Visual C++, and in full-stack web development. He works with advanced 2D and 3D mathematical models and with graphics programming in OpenGL and DirectX.
In 1999 he founded GeoStru, an international geotechnical software house whose catalogue he largely authored: slope stability and rockfall analysis, foundations and retaining structures, finite element analysis, geophysics and site investigation, hydrology and hydrogeology, and reinforced concrete design. Since 2016 he has run SC Engsoft S.r.l. in Cluj-Napoca, Romania, and he is technical and scientific consultant to GoMeeting. His most recent work is GeoStru.ai, a platform delivering geotechnical and civil calculation through natural-language conversation while keeping the analysis itself on deterministic, auditable algorithms.
Between 2005 and 2013 he co-supervised degree theses at the University of Calabria and the Mediterranea University of Reggio Calabria. He teaches accredited professional-development courses for geologists and engineers under accreditation from the Italian Consiglio Nazionale dei Geologi.
His peer-reviewed work includes papers in Green World Journal (2021), Marine and Petroleum Geology (2022), Journal of Mediterranean Earth Sciences (2022), Geosciences (2024) and Bulletin of Engineering Geology and the Environment (2026), together with memorie at the XXVII and XXVIII Italian National Geotechnical Conferences. He co-authored "Terre rinforzate" (EPC Editore, 2023) and "Terrae Motus".
He has been a member of AGI, ISRM, ISSMGE and AGI-IGS since 2014, and holds a certificate from AGS (Association of Geotechnical & Geoenvironmental Specialists).
