The specified regime for testing stiffness, particularly in shear, is important and can significantly affect the nominal value of 51002. shear stiffness of the bearing. Again, if AS If AS were adopted, a detailed review of the capacity reduction factors aw load factors specified in AS People using the contents of the document, whether directly or indirectly, should apply and rely on their own skill and judgement.
For continuous superstructures, lateral restraints may be omitted at some piers provided each section of the superstructure between expansion joints is adequately restrained.
AS – Standards Australia
Incorporate relevant NZS material omitted. The effects of seizure of a bearing are also to be considered. This major documentation would be mainly required to incorporate seismic design requirements and would probably take the form of a separate section with cross-referencing from the other sections. Otherwise the barrier design forces and methods of application, and barrier effective height requirements are essentially the same.
AS 5100.2:2017 Clause 18.3 Differential temperature
Key changes include definition of the different joint sealing elements and consideration of the decompression of compression seals due to concrete creep shortening. A review of the walkway UDL loading for appropriateness is also recommended.
Earthquake resistance is usually a dominant aspect of structural design in New Zealand, whereas it is a much less dominant aspect of design in Australia. For concrete bridges these temperatures provide a maximum range of 46o, but give a more typical ass of about 40o. For the SLS, the design return period is taken as 25 years.
In particular, in North America and the United Kingdom, the trend is towards eliminating bearings wherever possible and making the bridge structures integral. It is essential to retain this section of the Bridge manual and AS Supplementary documentation required if AS adopted.
See comments made for AS Parts 5 to 8. The Bridge manual separates the barrier into its elements and requires the following: This is also covered in the Bridge manual but perhaps is not as clearly expressed by the requirement that a permanent load, at the SLS, is to be replaced by 0.
For pedestrian bridges and walkways independent of road or rail bridge superstructures, the design load of 2 2 5 kPa applies up to a loaded area of 85 m before reducing linearly to 4 kPa at m.
As summarised above, without extensive supplements AS does not meet many of the New Zealand design requirements. Design loads for medium and special performance barriers This is reflected in the depth of coverage given to the topic by each of the two standards. Otherwise stormwater is to be collected and specific provision made for its disposal.

These factors are given in table 2. Supplementary documentation would be required to clarify the loads and load combinations if those specified by 51002 The following are two significant differences in the factors applied: Although separate standards for buildings and bridges are used in Australia and the United States, this is not the case in Europe where the materials codes Eurocodes have generally been developed to cover the range of commonly designed structures.
These differences are discussed in the aw of AS How bearing frictional forces are to be treated at the ULS could be more clearly expressed. On some qs of design it may be appropriate to reference or incorporate into the Bridge manual provisions from standards other than AS Beam stability during erection Appendix C of AS The three sections of AS Dead loads AS These comprise standards, with one technical advisory document.
An Sa in-house investigation by H Chapman noted that there was significant variation in the approach adopted by various standards ASBSAASHTO and Eurocodesand significant uncertainty about which standards predicted the characteristics of bearings most accurately.
The design loads encompass: Design loads for medium and special performance barriers 2.
What load factor should be applied for the ULS load case will require review in conjunction with a review of load factors for all ULS load combinations, should AS It is ae that New Zealand retain its current design traffic live loading until either the policy on 5100.2 vehicle limits changes or dedicated extra heavy vehicle corridors are formulated and implemented.
Bearings and deck joints 4 AS Possible ship impact on bridge piers is also required to be considered by the Bridge manual, but this load is not covered in AS The Bridge manual also provides a table of approved non-proprietary solutions.
