Austroads – Review of AS – Design Loads

Log In Sign Up. Review of Australian standard AS Bridge design with a view to adoption. This report is published in two volumes as follows: Executive summary, recommendations and parts 1 to 4 Volume 2: Parts 5 to 8 Keywords: The objective of the NZ Transport Agency is to undertake its functions in a way that contributes to an affordable, integrated, safe, responsive, and sustainable land transport system.

Each year, the NZ Transport Agency invests a portion of its funds on research that contributes to this objective. While this report is believed to be correct at the time of its preparation, the NZ Transport Agency, and its employees and agents involved in its preparation and publication, cannot accept any liability for its contents or for any consequences arising from its use.

People using the contents of the document, whether directly or indirectly, should apply and rely on their own skill and judgement. They should not rely on its contents in isolation from other sources of advice and information.

If necessary, they should seek appropriate legal or other expert advice in relation to their own circumstances, and to the use of this report. The material contained in this report is the output of research and should not be construed in any way as policy adopted by the NZ Transport Agency but may be used in the formulation of future policy.

The new organisation will provide an integrated approach to transport planning, funding and delivery. Acknowledgments The authors would like to acknowledge the contributions made to this project by the peer reviewers: Howard Chapman and Ian Billings, and the project steering group: Volume 1 Executive summary Scope and general principles Matters for resolution before design commences Road barrier performance level selection method Design loads for medium and special performance barriers Foundations and soil supporting structures Bearings and deck joints To complete this objective, the significant differences and gaps between current design requirements of AS and the Transit NZ Bridge manual 2nd ed and its supporting standards were identified.

The project considered the New Zealand regulatory environment and identified the measures required to enable the use of AS in New Zealand. Each section of the seven parts of AS was compared with the equivalent section of the Bridge manual and its supporting standards. A summary is given below of the main differences between the two design documents and the material needed in terms of supplementary documents to make AS suitable for application to bridge design in New Zealand.

The full extent of 5100.2 material that would need to be harmonised is considerable. See the appropriate sections in the report for a more complete identification of the supplementary material required if AS were adopted.

This area is not adequately covered in the Bridge manual. Road traffic Except at span lengths approaching m, the moving load model M is the dominant design loading specified in AS Adoption of the AS The Bridge manual HN and HO loadings are much simpler and give a satisfactory representation of the traffic load effects on New Zealand bridges.

The AS approach of applying reduction factors for multiple lanes loaded to individual lanes is similarly more complicated than the Bridge manual approach, and again the justification for this added complexity is questionable.

A review was recently undertaken of the design traffic live loadings appropriate for use in New Zealand and, as a result, revisions were made. Pedestrian and bicycle-path load The AS Which load specification is 5100. appropriate is not clear and would require a more detailed review if AS Minimum lateral restraint capacity The AS Collision loads AS The Bridge manual provisions for train collision were adopted from the Austroads bridge design code, and so bear some similarity to the AS The Bridge manual covers possible ship impact on bridge piers but this load is not covered in AS Kerb 51000.2 barrier design loads and other requirements for road traffic bridges AS Dynamic behaviour For 1500.2 bridges, AS For pedestrian bridges, the AS By comparison, the BS part 2 loading adopted by the Bridge manual, applies a sinusoidally varying load with a peak magnitude of N, which appears more reasonable.
