SeismoTank 5: Specialized Seismic Analysis Software for Liquid Storage Tanks

SeismoTank 5 is a specialized engineering software for the seismic design and analysis of liquid storage tanks, developed by Dr.-Ing. Habenberger . The software addresses the unique mechanical behavior of fluid-filled cylindrical tanks under earthquake loading, where the interaction between the tank wall and the contained liquid creates complex dynamic responses .

Key Features

Specialized Seismic Analysis

• Fluid-Structure Interaction: Models the dynamic behavior of liquid inside cylindrical tanks during seismic events, accounting for both impulsive (lower part of liquid moving with the tank wall) and convective (upper part sloshing) components .

• Comprehensive Code Compliance: Supports structural verification according to Eurocode 3 for stress analysis and buckling safety of tank shells .

Analytical Capabilities

• Stress Calculations: Computes axial, circumferential, and shear stresses at relevant points of the tank shell .

• Sloshing Analysis: Evaluates the natural periods and behavior of the liquid’s free surface oscillation.

• Buckling Safety Verification: Performs stress-based buckling safety checks as required by design codes .
