Energy Dissipation Analysis and Application of High-rise Structures Based on Coupling Beam Damper

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.
