A NEW TYPE OF SHEARING LEAD DAMPER AND ITS APPLICATION IN MILL BUILDINGS FOR A THERMAL POWER PLANT

It is introduced a new type of shearing lead damper,the shearing lead damper has simple structure and low production cost,performance tests showed that this damper can provide the similar hysteresis curve with that of conventional shearing lead damper.This new type of shearing lead dampers are used in mill buildings for a thermal power plant to reduce earthquake effect.Under the disturbance by small earthquakes,the damper can provide the structure with the additional 2% damping ratio,which was verified by non-linear analysis of time-hislory;in strong earthquake,through Pushover analysis,it was showed that the structure with the dampers has a good seismic performance,which may also be used in the post-earthquake.
