Seismic Analysis and Verification of Tanks.
SeismoTANK is a software application developed specifically for the seismic analysis and verification of storage tanks, in accordance with the main international codes (Eurocode 8 Part 4, API 650, ACI 350, AWWA and NZSEE). It is a user-frindly software based on analytical formulations and provides users with fast and accurate analyses for the vulnerability assessment of new and/or existing tanks, made of steel or precast and cast-in-place reinforced concrete.
The only software that allow dynamic ‘time history’ analysis as required by Eurocode 8 Part 4
Main Features
- Quick and fast definition of geometry, slenderness, panel and thicknesses
- Evaluation of slender and squat tanks for both rigid and flexible walls
- Ability to consider the impulsive, convective, and inertial masses for horizontal and vertical seismic action
- Behaviour factor and response spectra from national and international regulations, as well as user-defined spectra
- Equivalent analytical mechanical models that do not require advanced knowledge in Finite Elements Modelling
- Easy definition of seismic input (response spectrum or accelerogram)
- Clear interpretation of output, presented in both graphical and tabular form
- Advanced plots illustrating action effects and pressure trends
