The "TDAP III Structural Data Creation Support Program" is an additional option designed to assist in the creation of structural data for the nonlinear 3D dynamic analysis program "TDAP III," which is specialized for civil engineering and architecture. You can input structural data by drawing shapes on the screen. Additionally, it is possible to create structural data by leveraging the strengths of both visual structural input and the standard spreadsheet-based structural input of the Windows version of TDAP III. [Features] - Input structural data by drawing shapes on the screen - Multi-window display - Easy movement, rotation, zooming in, and zooming out of views - Concise menu structure limited to only the necessary functions *For more details, please refer to the PDF materials or feel free to contact us.

"ArkQuake" is a program for wave propagation analysis of one-dimensional layered ground based on the theory of multiple reflections and for liquefaction judgment. It is equipped with a function to automatically read seismic waveform files and supports a practical and sufficient number of layers and seismic points. The analysis results include a mode compatible with the standard program SHAKE. The deformation and acceleration results can be visually confirmed through an animation function for dynamic response. The liquefaction judgment complies with two standards: the 2012 Road Bridge Design Guidelines (Seismic Design Edition) and the Handbook for Liquefaction Countermeasures for Reclaimed Land (Revised Edition) from 1997 (judgment based on equivalent N values and equivalent acceleration). [Features] ■ Layer data can accommodate up to 200 layers ■ Input seismic points can be up to 65,536 ■ Built-in standard strain-dependent curves ■ Capable of analyzing two waveforms input into different layers ■ Supports multiple analysis options, including SHAKE-compatible mode *For more details, please refer to the PDF materials or feel free to contact us.
