Rolling system for use in biaxial earthquake damper for damping seismic collision in building, has base arranged parallel to line, where rolling mechanisms of damper are resonated, and rolling path is determined according to size of damper

摘要

The system has a base arranged parallel or perpendicular to a local subduction line of tectonic plates. Two rolling mechanisms of a biaxial earthquake damper are technically resonated in a position and in X and Y axes around plus or minus 100 mm of a rolling path. The mechanisms are rotated around 90 degrees. The path is varied and determined according to size of the damper. The rolling mechanisms consist of two rollers, and number and dimension of the rollers are determined according to size of vertical and horizontal loads. The system comprises steel profiles of rolling units.
