粘弹性阻尼器耗能性的影响因素分析

Analysis of factors affecting energy dissipation of viscoelastic dampers

粘弹性阻尼器在抗震结构中应用广泛,其耗能性是衡量抗震性能的重要指标。分析各类粘弹性阻尼器耗能性能的试验,发现环境温度、内部温度、应变幅值、激励频率、粘弹性材料等因素会对阻尼器的耗能性能造成影响,在设计时,需重点关注这些因素。

Viscoelastic dampers are widely used in seismic structures,and the ability of energy consumption is an important indicator for measuring anti-seismic performance.Lots of tests of energy dissipation performance were carried out.It is found that factors including ambient temperature,internal temperature,strain amplitude,excitation frequency and viscoelastic material will affect the energy consumption performance of dampers.These factors should be considered in the design of dampers.
