Analysis of Seismic Performance of Energy-dissipation for Prefabricated Concrete Beam-column Joint
摘要
Abstract
Analysis of prefabricated concrete beam column joint with sector lead viscoelastic damper (SLVD) is carried out and validated by comparing with experimental results.Comparison of seismic performance of joint between energy-dissipation and ordinary joint is conducted.Then analysis results in different design parameter cases are carried out for energy-dissipative specimen under different design parameters.It is shown that compared with ordinary prefabricated joint,the component joint with SLVD improves the initial stiffness and bearing capacity and enhances the energy-dissipation capacity of specimen in a certain degree.With the increase of axial com pression ratio,stress of concrete decreases obviously.Seismic performance of specimen improves with the increasing lead diameter,rubber hardness and sector radius,when the sector radius of damper is over a certain value,seismic performance of specimen degrades.关键词
