Analysis of fire endurance. Disasters, wave and seismic impacts

Spectrum R&D associates apply nonlinear numerical modeling for disasters, which can hardly be modeled in reality. Multi-variant analysis with respect to probability factors enable to develop reliable and at the same time cost-efficient structural solutions to provide for safety of people and installations. Several analysis approaches are unique for the Russian market.

Issues we solve:

• Seismic spectral analysis

• Non-linear seismic analysis for given accelerogram

• Seismic and hydro - elasticity of tanks

• Temperature field in case of fire

• Fire endurance of structures in case of fire

• Aerodynamic impact of tornados

• Impact loads and crush-tests

• Explosion impacts

• Wave loads on waterworks

• Loads at tsunami
