VOLUME 1 In the long term, the effort involved from New Zealand to maintain the bridge design standard is expected to be reduced because it will be shared with all the Australian states. It does not cover debris rafts acting on the bridge superstructure.
The Bridge manual presents a range of geometric width criteria that have been developed to suit New Zealand conditions. Matters for resolution before design commences 1. The design loads encompass: That the referenced list of documents presented in AS In addition, a review of the load factors adopted by AS Which load specification is more appropriate is not clear and would require a more detailed review if AS Road traffic Except at span lengths approaching m, the moving load model M is the dominant design loading specified in AS Foundations and soil supporting structures recommended to support the adoption of subsequent sections of this part.
Retention or otherwise of the current Bridge manual criteria for performance levels 6 and special has been discussed in section 1. The Bridge manual specifies a minimum requirement of 4.

Additions would be expected to include the documents referenced in the Bridge manual section 3. Thus the specification of criteria for special performance level barriers differs somewhat. Such pipelines are precluded from being carried inside box girders. If the Bridge manual requirements were retained, they should be revised to require consideration of both positive and negative differential temperature gradient.
An impact factor of 1. Ax for resolution before Need to reference relevant NZ and Transit documents. It is otherwise generally suitable for adoption subject to other parts referred to also being adopted. Overall conclusions on the adequacy of AS for adoption for bridge design in New Zealand and recommendations for the way forward are given following the executive summary at the front of the report.
Design loads Table 2.
Design loads for medium and special performance barriers This major documentation would be mainly required to incorporate seismic design requirements and would probably take the form xs a separate section with cross-referencing from the other sections. The warranty should cover all costs associated with rectification of a joint, including traffic control costs. It would be necessary to integrate these provisions with the Bridge manual procedures for assessing the strength of existing bridges by proof loading.
The Eng-Tips staff will check this out and take appropriate action. In the design of elastomeric and lead-rubber bearings, the following should be given particular 5100. Steel beams Section 5 of AS Steel and composite construction Only one of the eight AS Acknowledgments The authors would like to acknowledge the contributions made to this project by the peer reviewers: The forces referred to are forces on wall or slab type piers, perpendicular to their plane, arising from their orientation not being parallel to the direction of the water flow.
However, this option could be dispensed with particularly as horizontal rails are not permitted by the NZBC. If AS were adopted, a detailed review of the capacity reduction factors and load factors specified in AS Cross-references within the supplementary requirements and the commentary presented in sections 4.

zs This clause is not sufficiently clear and gives rise to the potential for those load factors to be ignored. These are shown in figure 2. Interaction curves for composite columns Appendix F of AS Section 13 Design of diaphragms Although the provisions of section 13 of NZS apply to diaphragms in buildings some of them are relevant to bridge design.
It fails to define the SM loading, which is assumed to refer to either the M or S loading.
Design of non-flexural members, end zones and bearing surfaces With a number of modifications section 12 of AS However it should be supplemented by the specific requirements of the Bridge manual, and the design flood events should be replaced by the Bridge manual requirements. It specifies the same normal design life years as AS
