To understand the vibration effects after the construction of structures! We conduct ground vibration analysis according to the purpose, target objects, and vibration sources.
Our company conducts predictive analysis of ground vibrations caused by moving vibration sources such as road traffic and railways, as well as fixed vibration sources like factory machinery and concrete placing machines, using computer simulation. In the simulation analysis, we create a ground model that reflects local ground information and input excitation forces that reflect local vibration data to output response values. Before constructing structures that are vibration sources (such as roads, railways, and factories) or buildings that are vibration receivers (such as residences, offices, and public facilities), we can predict the vibration impact on the buildings after construction. [Information Required for Vibration Analysis Using Computer Simulation] ■ Ground information (geological data from boring penetration tests) ■ Vibration information (vibration data from vibration measurements) *For more details, please refer to the PDF materials or feel free to contact us.

Company information
E&D Tech Design Co., Ltd. is a company that theoretically creates stable ground that is resistant to shaking and less prone to liquefaction by using its advanced proprietary technology known as the "WIB method." Focusing on vibration control, vibration reduction, and soundproofing against low-frequency vibrations from transportation, construction work, and factories, as well as seismic resistance and isolation against earthquakes, we conduct measurement surveys, simulation analyses, and design and construction of countermeasure methods. We aim to protect a comfortable environment through ground design and assist in creating happiness.
