The "SS21/DynamicPRO D-Tri Model Additional Options" is an optional software (program) for "SS21/DynamicPRO" that adds the Degrading Tri-Linear model to the lineup. ● For more details, please contact us or download the catalog.

The "SS21/DynamicPRO Curved History Option" is an option software (program) for "SS21/DynamicPRO" and "SS21/SuperDynamicPRO" that deals with analytical models possessing curved restoring force characteristics. ● For more details, please contact us or download the catalog.

The "SS21/DynamicPRO Additional Damping Option" is an optional software (program) that adds functionality to the "SS21/DynamicPRO" and "SS21/SuperDynamicPRO" for easily and accurately handling viscous and viscoelastic damping (vibration) dampers. It automatically performs modeling suitable for various dampers based on types that can nonlinearize the velocity-damping force relationship using bilinear, polylines, F=CVα, etc., and types that combine linear Maxwell elements in parallel (generalized Maxwell model). It also takes into account the stiffness of the damper mounting components. ● For more details, please contact us or download the catalog.

"SS21/Dynamic Surface Ground Amplifier 2007" is software (program) that calculates the amplification rate of acceleration Gs (the value of Gs specified in the table of Article 82-5, Item 5 of the Ordinance) based on ground survey results, in accordance with the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 598, which partially amended the Ministry of Construction Notification No. 1457. Using the calculation results, it can display graphical and numerical results such as "the relationship between Gs and natural period" and "acceleration response spectrum." ● For more details, please contact us or download the catalog.

The "SS21/Dynamic Surface Ground Interaction Option" is an optional license for extending the functionality of the "Surface Ground Amplifier 2007." This allows for the consideration of the effects of ground-building dynamic interaction in limit state calculation methods. Specifically, it enables the calculation of interaction-considered amplification factors (Gs), equivalent natural periods, equivalent damping constants, and allows for instant comparisons including cases that do not consider interaction effects. Additionally, during the calculation of interaction, the sway and rocking spring constants and damping constants are also determined simultaneously, allowing for the use of parameters in the sway-rocking model (SR model) in general earthquake response analysis. (Note: The "Interaction Option" cannot be executed alone.) For more details, please contact us or download the catalog.

The "SS21/Dynamic Restoring Force Characteristic Modeler" is software (program) that models the restoring force characteristics necessary for seismic response analysis of a mass point system, based on the load-deformation curves (skeleton curves) obtained from load increment analysis for each floor of a building. It allows for efficient work using files that are automatically generated when performing load increment analysis with the consistent structural calculation software (program) "Super Build/SS7." For more details, please contact us or download the catalog.

"SS21/ShakePRO-L" is software (program) that performs seismic response analysis of the ground based on the same overlapping reflection theory as the general-purpose analysis code SHAKE*. It can create design input seismic waves from seismic waves evaluated as outcrop (free) bedrock. *P.B. Schnabel, John Lysmer, H. Bolton Seed: "SHAKE" A COMPUTER PROGRAM FOR EARTHQUAKE RESPONSE ANALYSIS OF HORIZONTALLY LAYERED SITE, EERC, 1972-12 ● For more details, please contact us or download the catalog.

"SS21/SoilBase2008" is a database software (program) that stores various ground information (N values, soil types, FC values, qu values, VS values, VP values, etc.). It can also perform liquefaction assessments based on the "Guidelines for the Design of Building Foundations (2001 Edition)." It provides ground information for software such as "Super Build/SS7," "Super Build/BF1," "SS21/ShakePRO," "SS21/ShakePRO-L," "SS21/Dynamic Surface Ground Amplifier 2007," and any future software that requires ground information. ● For more details, please contact us or download the catalog.

"SuperDynamicPRO" is a particle system elastic-plastic seismic response analysis software (program) that can take into account the twisting of buildings. It allows for simultaneous input of seismic waves in the X and Y directions and can also examine the effects of forces applied at a 45-degree angle. Multiple parallel elements can be arranged in the seismic isolation layer and on each floor, and seismic isolation devices with different characteristics can be installed and evaluated individually based on their positions. The program comes standard with the "SuperDynamic Model Wizard" as an input support tool, enabling the creation of analysis data through interactive input on a 3D building image, allowing for visual confirmation during the process. Additionally, by adding the "DynamicPRO Additional Damping Option," it is also possible to conduct analyses that consider various damping devices with velocity dependence. For more details, please contact us or download the catalog.

The "SS21/Dynamic Vibration Animator" is software (program) that visualizes the vibration of buildings as animations based on the time history response results from the seismic response analysis software "DynamicPRO." It allows for visual confirmation of differences in vibration characteristics due to input seismic waves, structural types, and the effects on buildings when considering seismic isolation and damping elements. It is also possible to display different analysis results simultaneously, making it an ideal presentation tool. ● For more details, please contact us or download the catalog.

The "SS21/SuperDynamic Vibration Animator" is software (program) that visualizes the vibration of buildings as animations based on the time history response results from the seismic response analysis software "SuperDynamicPRO," which takes twisting into account.
