In recent years, there has been an increasing trend in the construction of steel-framed buildings. They are popular due to their short construction periods and the ability to accommodate long spans, making them suitable for a wide range of applications. On the other hand, steel-framed structures are more prone to vibration issues compared to reinforced concrete structures, and there have been increasing cases where uncomfortable vibrations lead to complaints. This document explains the reasons for the vibrations in steel-framed structures and summarizes key points to consider during the design phase to mitigate vibrations and ensure livability. If you are involved in design or are experiencing issues with vibrations in steel-framed structures, please feel free to download the document for more information.

• Earthquake-resistant construction method

There is a research report stating that during Typhoon No. 20 in 1979, many people inside a certain high-rise building reported physiological disturbances due to wind sway. The characteristic feature is a prolonged, large amplitude sway in the natural mode. It is typically represented by horizontal movements in two directions and twisting. In the full version of this document, we introduce the ways of swaying, how it feels, and the challenges, so if you are interested in the continuation, please feel free to contact us. [Excerpted Content] ■ Physiological effects on residents? A wind sway phenomenon that cannot be underestimated ■ What kind of swaying occurs? *This PDF document is an excerpt.

The "Super Atlas®" is a vibration isolation device that combines air suspension and mechanical suspension. By efficiently placing a safety protection guard that combines safety and protection on the main body, it achieves a lightweight and compact design. Additionally, even if there is a tilt due to unbalanced loads, it maintains a consistent level through an automatic leveling sensor. 【Features】 ■ High performance ■ No foundation required ■ Multi-purpose use ■ Flexible layout ■ Low cost ■ Free combination *For more details, please download the PDF or feel free to contact us.

• Earthquake-proof and vibration-damping equipment

Our company offers an air pressure-controlled up-and-down seismic isolation floor system. The air springs softly support the floor and reduce the forces of an earthquake. By supplying compressed air generated by a compressor to the air springs through a leveling valve while adjusting the air volume, the height of the seismic isolation floor is kept constant. Please feel free to contact us if you have any inquiries. 【Features】 ■ The natural frequency remains constant even when the load changes, so the seismic isolation effect hardly changes regardless of the size of the load or the position of the equipment on the isolation floor. ■ The use of air pressure-controlled friction dampers ensures a good walking experience. ■ By installing it in a horizontally seismic-isolated building, three-dimensional seismic isolation is made possible. ■ The space between the fixed floor and the seismic isolation floor is sealed with special hardware, preventing the intrusion of objects and dust. *For more details, please download the PDF or feel free to contact us.

• Earthquake-proof and vibration-damping equipment

The "Server Utena SUZ·SUR Series" is a seismic isolation device for server racks that protects important servers from massive earthquakes. It expands operational displacement while remaining compact due to the upper and lower rails. It consistently demonstrates stable seismic isolation performance, unaffected by the load it carries. Additionally, the structure ensures that the upper plate and rails do not separate. Please feel free to contact us if you have any inquiries. 【Features】 ■ Compact design that does not extend beyond the rack ■ Space-saving installation even when connected ■ Achieves approximately twice the load capacity of conventional types *For more details, please download the PDF or feel free to contact us.
