Take the tower one of Hangtian Technology Square

where coupling beam damper is applied as an example

the key technologies of the coupling beam damper

which is used to improve the building′s energy dissipation

is proposed in this paper.To verify the reliability of this new end-mounted area of the coupling beam damper

the stress-strain state of the pier and the damper is studied by ABAQUS.Then the original building

and the new building which have the coupling beam damper are combined by elastic-plastic time history analysis method in this paper.The analysis results show that the new end-mounted area of the coupling beam damper can not only ensure the damper working with the pier well

but also reduce the difficulty of construction.The coupling beam damper could dissipate the vibration energy and reduce the building′s response effectively.In this building

several defense levels are set by forming damper-reinforced composite beam

and the building′s energy consumption ability is improved.
