Development of Wind Locking System for Huge Ground Motion

Abstract

The number of dampers in isolation layer is determined based on required number for earthquakes or winds. In recent years, the target wind load have increased because the scale of building become taller and larger and the amount of damper required against winds is increasing. However, too many dampers in place to cope with large wind load, the isolation layer will not sufficiently during earthquakes. We develop a wind resistance lock mechanism that can lock the isolation layer displacement during winds in assumed range. The lock mechanism makes it possible to determine the number of dampers in isolation layer based on optimal value for earthquakes.
