In Japan, which experiences frequent earthquakes, seismic safety is a vital concern. Kajima has continually addressed itself to research and development in the search for new rational design and construction methods to provide greater safety.
Some results of these efforts have been incorporated into Japan’s largest prestressed concrete cable-stayed bridge, and into concrete arch bridges and suspended-deck bridges build with Fiber Reinforced Plastic tendons.
Kajima Corporation has also involved itself in development of aseismic techniques such as base isolation and aseismic reinforcement of existing bridges.
