Abstract
A sliding pendulum bearing is used to protect a construction against dynamic stresses from predominantly horizontal earthquake excitation with a first sliding plate, a second sliding plate and a slider movably arranged between both sliding plates, wherein each of the two sliding plates has a curved main sliding surface and the slider is in surface contact with a first main sliding surface of the first sliding plate and with a second main sliding surface of the second sliding plate, wherein the first main sliding surface is designed for a first load case and the second main sliding surface is designed for a second load case which differs from the first load case.

A sliding pendulum bearing for protecting a construction against dynamic stresses from predominantly horizontal earthquake excitation, having a first sliding plate, a second sliding plate and a slider movably arranged between both sliding plates, wherein each of the two sliding plates has a curved main sliding surface and the slider is in surface contact with a first main sliding surface of the first sliding plate and with a second main sliding surface of the second sliding plate, wherein the first main sliding surface is designed for a first load case and the second main sliding surface is designed for a second load case which differs from the first load case, wherein the first and the second load cases represent specific peak ground acceleration values of corresponding earthquakes.
A method for dimensioning a sliding pendulum bearing for protecting a construction against dynamic stresses from predominantly horizontal earthquake excitation, having at least a first sliding plate, a second sliding plate and a slider movably arranged between both sliding plates, wherein each of the two sliding plates has a curved main sliding surface and the slider is in surface contact with a first main sliding surface of the first sliding plate and with a second main sliding surface of the second sliding plate, wherein the first main sliding surface is designed for a first load case and the second main sliding surface is designed for a second load case which differs from the first load case, wherein the first and the second load cases represent specific peak ground acceleration values of corresponding earthquakes.
