Failures have been recorded where zs dimensions were inadequate and where rotation of the bridge deck ends under traffic loads were not accounted for. Dead loads AS Extension of the list of notations may 510.2 required to incorporate notation from any supplementary documentation used to support other adopted sections of AS Collision protection AS The amendment is based around adoption of AS 510.2 Loads and load combinations If AS Most New Zealand bridge construction has relatively short spans, allowing elastomeric bearings to be used, and resulting in few problems of corrosion of critical bearing components.

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.

AS 5100.2:2017 Clause 18.3 Differential temperature

Interaction curves for composite columns Appendix F of AS Seismic design procedures are mainly covered in section 6 of AS Road traffic barriers AS The most significant difference between this section and NZS is the restriction on the use of the various ductility grades of reinforcement.

Should the AS Any other forces that may act, and their combination with other loads, in addition to those specified, are also to be considered in a manner consistent with the principles set out in AS In other respects the AS Section 1 of AS Composite box girders Section 7 of AS Neither is the specification of an arbitrary total force capacity logical as the length and mass of superstructure to be restrained may vary widely from structure to structure.

Where a structure has limited plastic capacity, differential settlement is to be included at the ULS using a load factor of 1. To highlight the differences, table 1.

Design for fire resistance Section 5 of AS The Bridge manual has no similar requirement. Conclusions on AS These requirements are not covered by AS The Bridge manual, more simplistically, adopts a single drag coefficient for all situations which requires correction as noted above and an angle of attack factor derived on the same basis as for piers.

Retention of the Bridge manual criteria for performance levels 6 and special would need to be considered. An interim approach would be to maintain the status quo with the Bridge manual adopting NZS but with additional supplementary material to incorporate relevant AS Development of a design fatigue load spectrum applicable to New Zealand conditions is necessary whether or not AS A detailed review is required.

Not covered in AS External restraining cleats should not be used.

The deck surface reference temperature for the temperature gradient curve is varied according to the region of Australia. This is to act as a dam to retain the surfacing and to isolate the surfacing from any tensile forces imposed on the deck by the joint system.

The design of drainage systems should accommodate the movement across the deck joints of the bridge of not less than one quarter of the calculated relative movement under the ULS design earthquake conditions, plus long-term shortening effects where applicable, and sa third of the temperature induced movement from the median temperature position, without sustaining damage. Deck joints are also a potential source of deterioration to the bridge structure itself where leaking joints can promote corrosion of underlying structural elements.

In view of what appears to be a very high dynamic excitation load being applied by AS The corresponding Bridge manual requirements are: Second order elastic analysis The wording of appendix C of AS Application Section 2 is suitable for adoption should AS Matters for resolution before Need to reference relevant NZ and Transit documents.

On zs other hand, the AS The design of earthworks for approach embankments and cuttings is covered in the Bridge manual, but not included within the scope of AS The Bridge zs separates the barrier into its elements and requires the following: In New Zealand, where specialist resources are limited, it seems best that materials design codes should cover the widest possible range of structures.
