High-Capacity Polyurethane Seismic Isolation Bearing
Overview
A laminated isolation bearing composed of polyurethane (as polymer elastomer) with reinforcing steel plates and sealing plates, achieving design compressive stress over 3 times higher than conventional rubber isolation bearings
Scope of Applications
Ideal for building structures and bridges (continuous T-beams, small box girders, low-tonnage wide box girders) in seismic zones with intensity IX or below
-
35MPaDesign compressive stress reaches

190MPaUltimate compressive stress reaches
-
250%Shear deformation reaches
Features
-
Long Service Life & Superior PerformanceHigh damping, large horizontal stiffness, complete self-centering capability, and extended material durability.
-
High Load Capacity
采用新型高分子材料代替橡胶材料。高分子材料赋予支座高弹性变形及复位、高耗能和高承载力的功能。与常规橡胶减隔震支座相比，同尺寸下竖向承载能力提升了2~3倍。采用其替代橡胶支座，可以减少支座个数及尺寸，有利于施工安装。
