STUCTURE AND MECHANICAL CALCULATION
ALPHA TECHNIQUES offers you his experience and expertise in structure calculation for the following topics:
- Linear and nonlinear static analysis
- Modal analysis
- Buckling analysis
- Harmonic response (sinusoidal loading of amplitude and frequency known)
- Spectral response (example: earthquake)
- Transient dynamic analysis (variable loading over time)
- Thermal analysis
Moreover, we carry out complementary manual calculations to check assemblies (bolts, welding, hinge pins…)

Software
The software we are use
- RDM7 (linear static analyses -2D/3D beams)
- ANSYS (calculation by finite elements)
- ABAQUS (calculation by finite elements)
- ISYMOST/NSO (beam/finite elements/code check)

We have a good knowledge of the classification rules of ships (BV, DNV, IACS, RINA, ABS…), in particular for ship structure and stability
Moreover, we use the following rules:
- Eurocodes (0, 1, 3, 8 and 9)
- European standards NF EN
- AISC
- FEM (lifting)
- CODAP/CODETI
- API RP 2A WSD (jacket)
