In modern bridge structures, bridge bearings and expansion joints are commonly the source of most maintenance and performance issues. The report is a literature review that summarises the features, usage and performance of bridge bearings and expansion joints throughout the world. The common failures and the proposed solutions to rectify the failures of the most used bearings and expansion joints are discussed. As well as information on the current practice in manufacture and supply of bridge bearings and expansion joints of Australian providers. The report also provides recommendations on future directions to overcome this issue.

An expansion joint or movement joint is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems, ships, and other structures. Building faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced. Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures. They stop the bridge from bending out of place in extreme conditions, and also allow enough vertical movement to permit bearing replacement [1] without the need to dismantle the bridge expansion joint. There are various types, which can accommodate movement from 30 to 1, millimetres 1.

Ferdinand Tschemmernegg, University of Innsbnick. Preface It is my hope that this treatise will serve as a textbook for students and as information for civil engineers involved in bridge construction. My intent was to give a short guideline on bearings and expansion joints for hridge designers and not to mention all the requirements for the manufacturers of such products. These requirements are usually covered by product guidelines. Not all the references are related to the content of this document. They are more or less a collection of relevant papers sometimes dealing with special problems. I express many thanks to Prof.

Беккер покачал головой: - Отнюдь. Тут написано - Quis custodiet ipsos custodes. Это можно примерно перевести как… - Кто будет охранять охранников! - закончила за него Сьюзан. Беккера поразила ее реакция. - Сьюзан, не знал, что ты… - Это из сатир Ювенала! - воскликнула.  - Кто будет охранять охранников.

АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной. Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени. Устройства были обнаружены и удалены за целых три часа до намеченного срока взрыва. Сьюзан знала, что без ТРАНСТЕКСТА агентство беспомощно перед современным электронным терроризмом. Она взглянула на работающий монитор. Он по-прежнему показывал время, превышающее пятнадцать часов. Даже если файл Танкадо будет прочитан прямо сейчас, это все равно будет означать, что АНБ идет ко дну.
