An error exists in the Bridge manual derivation of forces acting on face areas normal to the flow, in that the angle of attack factor applied in deriving K should be taken as 1. A detailed investigation of the basis for the AS It would be necessary to integrate these provisions with the Bridge manual procedures for assessing the strength of existing bridges by proof loading.

Forces resulting from water flow The AS Where gaps greater than 25 mm could develop between adjacent panels, bridging plates are to be provided. These references would be drawn from the references listed in section 4. In the case of AS For other box girders BS parts 3, 5 and 10 are adopted. The design loads and forces are to be considered as acting in ax as set out in section 22 of AS The dynamic load factor is also applied to the top slab of buried culvert type structures but is reduced with depth of fill over the slab from the ae ground value at ground surface to 1.

This research builds on a previous Transfund NZ project: A review of the analysis procedure given in section 4 of AS For this reason, they would be relatively easy to incorporate by supplementary documentation or by direct reference to the AS provisions.

Acknowledgments The authors 500.2 like to acknowledge the contributions made to this project by the peer reviewers: Otherwise the load factor varies 1. In general the load combinations are taken from AS The main advantage of adopting AS Other than the requirement for all parts of the structure to be interconnected to provide structural robustness, the Bridge manual does not present specific requirements to resist lift and buoyancy actions.

Both codes draw attention to the critical design condition possibly occurring at a return period less than the maximum ULS return period, but only AS In four cases, a concurrent serviceability load is to be added where they result in a more severe effect. Design loads for medium and special performance level barriers The differences between the requirements given in appendix A of AS Bridge manual provisions for concrete bridge design The Bridge manual requires the design of concrete bridges to be in accordance with NZSwith modifications and additional provisions in the following areas: Are you an Engineering professional?

The coverage of section 11 of AS In the design of elastomeric and lead-rubber bearings, the following should be given particular attention: This is not covered in the Bridge manual. Walkways not accessible to traffic are to be designed for the first two loads above, but not the HN wheel overload.

Manufacturing aas for 4.

AS 5100.2:2017 Clause 18.3 Differential temperature

As summarised above, without extensive supplements AS does not meet many of the New Zealand design requirements. It would be a retrograde step if New Zealand were to convert to the current Australian practice of structure-specific materials design standards. Foundations and soil supporting structures 3.

Design loads bounds are to be considered through applying a load factor of 1. However, this option could be dispensed with particularly as horizontal rails are not permitted by the NZBC.

Because of the close relationship of NZS to the ACI concrete design standard and the application of NZS for the design of most concrete structures in New Zealand since it was first introduced in the s, New Zealand engineers have become very familiar with the basis of the provisions, their application in design and the notation and nomenclature.

The required amendments include: Although the provisions are directed mainly towards building frames, they are also relevant to bridge pier frames and joints at the intersections of bridge pier columns with footings.

The Bridge manual has no similar requirement. Whether there are advantages in having separate materials design standards for different types of structures eg buildings and bridges is a debatable point. However, it does not cater adequately for the needs of the Transit NZ Highway Permit System and if adopted supplementary documentation would be required to incorporate provisions that address the information needs of the Highway Permit System and administration of bridge posting under the Heavy Motor Vehicle Regulations.

For this reason it should be included. Parts 5 to 8 Keywords: That project outlined the coverage desirable in an ideal road structures design manual and included a comparison of the Austroads Highway Bridge Design Code the predecessor of AS with the Bridge manual.

Austroads – Review of AS – Design Loads

The Bridge manual considers dynamic loading only as an additive to the static loading by factoring the static loading effects on a structure above ground by a dynamic load factor derived from figure 2. Assessment of geotechnical strength reduction factors for piles As indicated above for section 11, a review would be required of the strength 5010.2 factors at the top end of the specified ranges given in this appendix.

As noted previously in section 3. The Bridge manual requires the investigations to establish the characteristics of the surface and subsurface soils, their behaviour when loaded, the nature and location of any faulting, and the groundwater conditions.

It provides useful design information for box girder superstructures that is not presented elsewhere in New Zealand design standards. Construction forces and effects AS Foundations and soil supporting structures In the evaluation of foundation settlements, AS Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

A range of design load information is specified to be presented on the front sheet of the bridge drawings.
