Overview

For our first technical seminar of the year we are talking Bridges! Starting with the first bridge project in Australia using the steel concrete composite dowel construction method, followed by the use of continuous teeroff beams on the Northlink 2 project.  Tonight you will get both designers and client perspectives.

Topics

BRIDGE 0270A – AUSTRALIA’S FIRST STEEL CONCRETE COMPOSITE DOWEL BRIDGE WITH EXTERNAL REINFORCEMENT
 
Bridge 0270A is the first bridge project using the steel concrete composite dowel construction method in Australia.  The bridge beams selected for the replacement in the South-West Region of Western Australia consists of halved I-girders acting as extremal reinforcement.  Due to its load capacity and favourable fatigue strength, one composite dowel is able to replace a group of shear studs which simplifies the reinforcement installation.  This innovative method has proven its structural effectiveness and financial benefits backed up by years of research across Europe documented in several design guides and a general building authority approval in Germany.  The presentation will discuss the design, manufacturing and construction challenges as well as the identified benefits of this pilot bridge project applying the composite dowel strip design method.

Neil Westmacott, WSP
Neil has over 28 years of experience in the civil engineering profession.  He has extensive experience designing and assessing bridge structures in prestressed concrete, steel-concrete composite and prestressed-concrete composite.  He has been involved in bridge designs incorporating construction methods varying from heavy lift/transported structures, precast, trussed, cast-in situ and segmental construction.
 
Peter Newhouse, Main Roads WA
Peter has worked in Main Roads WA for 18 years.  Prior to that, he worked in the water industry for 18 years.  While in Main Roads WA, Peter has been responsible for managing bridges on the State and National road network in the South West Region of WA.  He has also worked closely with other bridge owners in the Region such as local government, by providing technical advice and programming bridge repairs and refurbishment on their behalf.
 
 
 
SIMPLIFIED CONTINUITY FOR TEEROFF BRIDGES
 
Bridges comprising precast Teeroff Beams made continuous offer a number of advantages, and have been used increasingly on projects in Western Australia. Typical methods of achieving continuity rely on specialised construction techniques or onsite formwork. To maximise the combined benefits of a continuous design and precast Teeroff beams, the design of the bridge, and in particular the stitch detail, needs to be as simple as possible.
 
On Northlink Central Section, a new method of achieving continuity for the highly skewed multi-span bridges was devised. The design innovatively used the standard Teeroff geometry and a voided end block to construct a cast in-situ continuity stitch without any additional onsite formwork. The geometry of the continuity stitch eliminates the need for couplers in the Teeroff beam, or bars protruding through the stitch formwork.
 
This presentation discusses the detail used for Northlink Central Section bridges and the resulting savings in materials, formwork and construction costs.
