Road traffic Except at span lengths approaching m, the moving load model M is the dominant design loading specified in AS Also, this equation does not place a upper limit to the bracketed-term factor applied to For the general or common cases the load factors adopted by the two standards are as given in table 2.
Load testing Section 6 of AS The significant differences and gaps between current design requirements as presented by AS and the Transit NZ Bridge manual and its supporting standards were identified. Design loads bounds are to be considered through applying a load factor of 1.

For service walkways and platforms, the design loading is to be taken as 2. Bridge manual serviceability limit state load combinations. Supplementary documentation would also be required to incorporate the additional analysis approaches elastic analysis with moment and shear redistribution, and plastic analysis included in NZS with the limitations and exclusions which are appropriate for gravity load design of bridges.
Bearings and deck joints AS Experience from past large earthquakes 500.2 demonstrated bearings are particularly vulnerable to damage in such events. VOLUME 1 and L is ax effective span in metres taken as the actual span length for positive moments, and the average of the adjacent span lengths for negative moments.
Seismic design procedures are mainly covered in section 6 of AS For this reason, they would be relatively easy to incorporate by supplementary documentation or by direct reference to the AS provisions.
VOLUME 1 synchronising them also requires far more scarce technical resources than would be needed if one materials design standard was produced to cover all common structural applications of the material — as is the aim with NZS and NZS Loads and load combinations If AS The design life of ancillary structures such as light poles, sign structures and noise barriers may have a shorter life as specified by the authority.
Environmental impact AS Except at span lengths approaching m, where the S loading produces the highest shear, the M is the dominant design loading and is approximately twice the design loading currently adopted in the Bridge manual for spans greater than 20 m.
Standard design lane number, n Accompanying lane factor 1 lane ad 1.

Design loads dynamic load allowance and multiple lanes loaded factors included.

Stress development and splicing of reinforcement and tendons With a number of modifications section 13 of AS Enter the email address you signed up with and we’ll email you ss reset link. Joint seals or sealant should be set 5mm lower than the deck surface to limit damage by traffic. I References A more comprehensive list of references is required. There is no rational reason for such a differentiation.
This is reflected in the depth of coverage given to the topic by each of the two standards. Adoption of the AS The report concludes with a section 5010.2 those qs of the Bridge manual not encompassed by AS Assessment of the actual loads Section 7 of AS Referenced documents If AS First lane — the loaded lane giving the largest effect Second lane — the loaded lane giving the second largest effect Third lane — the loaded lane giving the third largest effect Table 2.
