Modern, economical, low maintenance and durable bridge solutions have been developed for the design of short span bridges required for the East Coast Expressway project in Malaysia. The design was developed by the Consulting Engineer working closely with the contractor on a design and build basis for this turnkey project
This paper presents the designs of 9 prestressed concrete bridges developed by the Benaim Group in Association with RB Perunding for this project. One of the main features of these bridges is the continuous and integral connection of the bridge deck with its columns and abutments, eliminating the need for expansion joints, thus improving aesthetics, increasing durability as well as reducing maintenance requirements.
Two forms of construction were adopted for these bridges: one using post-tensioned precast concrete ‘T’-beam for longer spans, and the other using in situ prestressed concrete twin ribs. Advantage has been taken of Malaysia's moderate climate and low temperature range, and bridge decks up to 85m long have been made integral with their abutments while, the normal practice in the UK is to limit integral bridge lengths to 60m.
