Reinforcement of the Foundation and Seismic IsolationThere are cases where the foundations have beenreinforced (slides 75-76) and those that have had seismicisolation systems introduced (slides 77-79).A Case Study of Reinforcement: Pump House(slides 80-83) The facilities were built in the early 20thcentury and are composed of a group of masonry structures.Therefore, as they each moved separately when affectedby vibration, there was a problem of their lacking seismicperformance as a whole. In this case, it was decided thatit would be effective to employ shock transmitters on thesteel-frame grid (partially extant) on the roof top. Braceswere introduced to connect the separated elements andthis equipment was attached onto the connection (slide83, on right), so that they would move as one whole.It is a contemporary method in which collision of thedifferent parts of the building could be avoided and seismicperformance could be increased.
