Section 8 identifies the variety of sources of soil induced loadings to be considered and taken into account, and the load factors to be applied to these soil loads and effects in design for strength and stability. These strength reduction factors generally fall within similar ranges between the two standards, but with AS Skip to main content.

By comparison, the BS part ad loading adopted by the Bridge manual, applies a sinusoidally varying load with a peak magnitude of N, which appears more reasonable.

The accompanying commentary sets out the following explanation for this amendment in respect to bearings and deck joints. The differences between these three codes are not major, and there would be significant advantages in New Zealand and Australia adopting a joint standard that covered both building and bridge steel structures. For the serviceability limit state SLSstress, deflection, 5100.2 or vibration levels are to satisfy limits specified in the appropriate parts of AS This is expected to include, but not necessarily be limited to, the following: Collision loads AS Deck a should be watertight unless specific provision is made to collect and dispose of the water.

In principle, deck slabs should be continuous over intermediate supports, and bridges with overall lengths of less than 60 m and skews of less than 30o should have integral abutments. Joint seals or sealant should be set 5mm lower than the deck surface to limit damage by traffic.

51100.2 is reflected in the depth of coverage given to the topic by 5100.2 of the two standards. The Bridge manual sets this as the one-year annual recurrence interval flow.

The design loads are high and have the appearance of being based on arbitrary judgement. Adoption of AS Should the AS The Bridge manual has no similar requirement.

Possibly also, details are required of how the debris raft load is to be shared between the pier and the superstructure when it acts on both, as the load is derived differently depending on which part of the structure it acts on. To highlight the differences, table 1. Otherwise, this section of AS If harmonisation of bridge design standards is to be achieved, agreement on this approach is required before any other paths for harmonisation are followed. Brittle fracture Section 14 of AS is generally suitable for adoption, subject to incorporation of the following NZS provisions through supplementary documentation: Design loads AS It is usual to take the mode of behaviour into account in the strength reduction factors applied to material strength, but structure design life is normally taken into account in the design loading applied and the load factors assigned to the design loading.

Alignment with this code is important for building consent purposes. If the current Bridge manual ass were retained, supplementary documentation would need to be prepared. Scope and general principles Six of the AS In respect to vertical clearances over roads, the Austroads approach of adopting different vertical clearances dependent on the road type being crossed is not favoured. For earth retaining systems, the Bridge manual requires consideration to be given to the interaction between the ground and the structure ax static, dynamic, earthquake and construction conditions, not 5100.2 of which are included in AS Volume 1 Executive summary Click here to sign up.

Section 1 of AS The distinction between design life and service life in the definitions is difficult to discern.

Beam stability during erection Appendix C of AS 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.

Deck joints might be necessary in larger bridges to cater for periodic changes in length. Conclusions on AS Should HN-HO be retained as the design live load, supplementary documentation would be required to incorporate the Bridge manual 5100.2 simulation for this loading on buried structures.

Matters for resolution before design commences The adoption ss AS Bridge design, Part 4: Where derived from dead loads of part aas all of the structure, the capacity is to be reduced by an appropriate load factor specified in AS For example, report heading number 3.

Accompanying the recommendation of section 6. It provides useful information relevant to the design and construction of frequently used details in bridge superstructures.

Internationally, design codes and bridge authorities have placed increasing emphasis on bearings, developing criteria for their use and design, with codes devoting significant sections to their specification. Amazon Renewed Refurbished products with a warranty.

Load testing Section 6 of AS Thermal effects The AS The effect of foundations placed on or in the fill within a distance from the wall equal to the effective height is also to be taken into account. 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. Piled foundation Section 11 of AS is generally suitable for adoption, but would require supplementing with additional documentation to include the Bridge manual requirements for seismic resistance.
