Solution Overview

Seismic force for verifying the safety of buildings is indicated as response spectra by regulations such as the Building Standards Act in Japan. However, we need time-history seismic waves, which fit the response spectra, to perform time-history response analyses. Our software, ARTEQ for Windows, assists you in preparing those seismic waves.

Characteristics

  • Seven built-in typical target spectra indicated by Japanese regulations
  • Input and save any target spectra (acceleration, velocity)
  • Various built-in envelope functions
  • Edit and output various graphs relevant to calculating seismic waves
  • Read target spectra calculated by our seismic load evaluation software, SeleS for Windows
  • Plot results to compare between calculated and target spectra
  • Output results as CSV format files

Functions

ARTEQ for Windows assists you in calculating artificial time-history seismic waves using the following functions.

Setting Target Spectrum

Our software, ARTEQ for Windows, has seven built-in response spectra indicated by Japanese regulations. It also has functions to input other desired target spectra, including the import of output data from our load evaluation software, SeleS for Windows.

Setting Phase Spectrum Function

ARTEQ for Windows can use phase spectra from observed seismic records and uniform random numbers to calculate artificial seismic waves.

Setting Envelope Function

ARTEQ for Windows includes several typical envelope functions, since it is necessary to set envelope functions when you use random numbers as phases. It also has a function that allows users to set other envelope functions.

Setting Function for Suitable Conditions

To calculate a seismic wave that fits within a target spectrum, you must set suitable conditions within a permissible variance range in order to perform the convergence calculations. You can choose and set suitable conditions, such as a minimum spectrum ratio, S.I. ratio, and coefficient of variation.
