Extended Lifespan for Bearings and Expansion Joints

摘要

Many decades of experience, including analysis of actual damage, has led to improvement in thedurability of bridge bearings and expansion joints. Basic recommendations are given usingsimple principles for the arrangement and the design type selection. New technologies for slidingelements to eliminate wear problems are described. Complementary advice for dimensioning,anchorage equipment, manufacture and installation ensure the highest performance level atacceptable costs. Links to applicable international standards and national regulations simplify theprocess.
