Seismic isolation system

摘要

A seismic isolation building system, and method thereof, for buildings and other structures that is well suited to protect lightweight low rise buildings including houses against earthquakes, particularly where the structure is located in low lying wet regions subject to liquefaction. The system utilizes a platform with piles extending from the platform into a ground, wherein the piles are connected to the platform via at least one shear bolt that links a platform plate to a pile. The shear bolt or bolts are designed to shear in an event of a predetermined level of seismic activity freeing the platform and structure on the platform to move independent of the piles. Post seismic activity, the platform and structure are moved, repositioned and/or re-fixed to new or existing piles thereby minimizing damage to the structure and hence repair costs.

主权项

1. A seismic isolation building system comprising:
at least one structural platform laid horizontally on a ground surface providing a foundation for a structure thereon; a plurality of piles extending from the platform into the ground surface on which the at least one structural platform is placed; at least one plate inserted between the pile and platform that is fixed to the platform, wherein said at least one plate comprises at least one platform plate; and, at least one further plate fixedly linked to the pile and which abuts the platform plate, wherein said at least one further plate comprises at least one pile plate; wherein the plurality of piles are connected to the at least one structural platform via at least one shear bolt that links a platform plate of said at least one platform plate to a pile of said plurality of piles, and, wherein the at least one shear bolt is designed to shear during a predetermined level of seismic activity freeing the at least one structural platform to move independent of the plurality of piles, and which, post seismic activity, be moved, repositioned and/or re-fixed to new piles or existing piles of said plurality of piles.
