弹塑性钢阻尼器减隔震原理在桥梁工程中的应用

On Seismic Isolation & Reduction Principle of Elastic-plastic Steel Damper(EPSD) Applied in Bridge Engineering

弹塑性钢阻尼器是金属耗能减隔震装置,是高震区建筑、桥梁工程的减隔震产品之一。阐述弹塑性钢阻尼器的减隔震原理,在桥梁工程中选用弹塑性钢阻尼器及产品参数计算方法,以及弹塑性钢阻尼器制造、施工安装等环节。

As a Metal energy consumption damping device, the elastic-plastic steel damper( EPSD) is one of products used in architectures and bridges in the high earthquake zone. Seismic isolation & reduction principle of EPSD is discussed in this paper, and moreover, the way to choose EPSD in bridge engineering, its parameter calculation methods, manufacture process and construction & installation sectors are also mentioned as well.
