| 摘 要： | 在高地震烈度区的桥梁结构,设计时地震力起绝对控制作用,此时如果采取结构本身的"硬抗"不仅增加设计负担,并且大量浪费原材料,同时增加了经济负担。一般情况下,可采取"延性设计"和"减隔震设计"来达到减震耗能的目的。该文针对某8度区桥梁,采用国内外较常用的整体型减隔震装置——铅芯橡胶支座对其进行减隔震设计,计算结果表明铅芯橡胶支座既能延长结构的周期,又能耗散地震能量,具有良好的减隔震效果,是一种比较理想的减隔震装置。

| Abstract: | Seismic force plays an absolutely control role in bridges design in high seismic intensity area.In this case,not only the burden of design and economic will be increased but also lots of materials will be wasted by the traditional design method.Generally,the purpose of damping could be achieved by ductility design and seismic isolation design.LRB which is the overall seismic isolation device commonly used in domestic and international,has been applied to the bridge in district 8 degrees in this paper.The re... |
