REPLACEMENT OF EXISTING MECHANICAL BEARINGS WITH ELASTOMERIC BEARINGS FOR AHMAD SHAH BRIDGE, TEMERLOH, MALAYSIA

The Ahmad Shah Bridge is a high level bridge with main spans of the bridge consisting of two continuous spans of steel twin-box girders approximately 150 m and 120 m in length. In June 1997 it was discovered that the existing mechanical roller bearings at the west abutment had damaged severely to the extent that the roller had been displaced. The existing bearings are of HiLoad type mechanical bearings. Despite that it is a common practice of Public Works Department Malaysia (PWD) to use mechanical bearings for spans exceeding 50 m, PWD has decided to use elastomeric bearings of natural rubber to replace all the four existing bearings at the abutment. This paper discusses the investigation carried out to determine the main causes of the problem, as well as the design, installation and monitoring of the new elastomeric bearings. Some cost comparisons are also made to highlight the amount of savings made by the Department's bold decision. For the covering abstract see IRRD E104152.
