    • A seismic isolation bearing comprises a lower plate, an upper plate, and a cylindrical roller in rolling contact with an upwardly facing, bearing surface of the lower plate and a downwardly facing surface of the upper plate. The lower plate is fixable to a base, while the upper plate is fixable to a superstructure. One or both bearing surfaces are sloped to form a central trough at which the cylindrical roller resides under normal weight of the superstructure, and toward which the roller is biased when displacement between the plates occurs. A pair of sidewall members are fixed to the lower plate to withstand strong forces directed laterally with respect to the isolation axis along which rolling displacement occurs, and a pair of sliding guides carried one at each end of the roller provide dry frictional damping as they engage an inner wall surface of a corresponding sidewall member.
    • 防震隔离轴承包括下板,上板和圆柱滚子,其与下板的向上的支承表面和上板的向下的表面滚动接触。 底板可固定到基座上,而上板可固定到上层建筑。 一个或两个支承表面是倾斜的,以形成中心槽,圆柱形辊位于上部结构的正常重量的位置处,当板之间发生位移时,辊被偏压。 一对侧壁构件固定到下板上以承受相对于隔离轴线横向移动的强力,沿着该轴线发生滚动位移,并且在辊的每个端部承载的一对滑动导轨在它们接合时提供干摩擦阻尼 相应侧壁件的内壁表面。

    • A method for producing cylindrical hollow bodies bearing on the ground along one generatrice, of large cross sectional area, by assembling on site previously prepared longitudinal components.The method consists in determining by calculation the optimum cross-sectional profile of said hollow body as a function of known parameters concerning the site, conditions of use of said hollow body and its inherent characteristics; divising said optimum cross-sectional profile into adjacent sections each corresponding to a longitudinal component of the hollow body and together providing a substantially continuous interior surface; and giving the transverse wall section of at least some of said components a variable thickness for adapting the latter component to the stresses to be exerted thereon.
